Meet the Designers Committed to Making Socially & Environmentally Conscious Jewelry
There’s more to diamond jewelry than its sparkle. More designers are committed to creating creating socially conscious and sustainable jewelry through practices which include responsibly sourced stones, ethically mined gold, and crafted in workshops that adhere to a code of conduct that protects its workers and minimizes its carbon footprint. That might not sound sexy, but it gives jewelry a feel-good factor that is priceless.
“It’s heartwarming when a bride can tell you where her diamond is from and get a clear idea of the people that have benefited from it,” says designer Thelma West, who sources her diamonds from Botswana, where she sees firsthand how the industry benefits the local communities. “I’d also just like to leave a better world for my daughters.”
Meet the Author
- Jill Newman is a jewelry authority, editor, and storyteller with over 25 years of experience, having reported from diamond mines in Africa, cutting workshops in India and Belgium, and ateliers around the world.
- She serves as Editor-at-Large for the Natural Diamond Council, with additional bylines in The New York Times, Town & Country, Elle Décor, and Robb Report.
That sentiment is permeating the diamond jewelry industry. At a time when there’s so much greenwashing, it’s inspiring to meet socially and ethically conscious designers who are going to great lengths to create businesses that are gentler on the planet. That includes knowing a stone’s origin and the craftspeople who make the pieces, buying Fairmined gold, and donating a percentage of profits to philanthropic causes, and more.
Did I mention that the diamond jewelry is fabulous? These more socially conscious, sustainable jewelry designs are stylish, contemporary pieces that speak to the way we live and dress today.
This is a new series that highlights designers and brands that are committed to creating responsibly sourced, sustainable jewelry and employing ethical practices.
Catherine Sarr, Almasika
When Catherine Sarr visited diamond mines in Botswana a few years ago, she was profoundly moved seeing firsthand how the industry has helped advance the country and its people. “It adds another layer to the diamond story,” said the Chicago-based designer. When she sources diamonds from Botswana, she shares those stories with her clients, who increasingly want to know the journey of their jewels.
When Sarr established her business in 2014, social responsibility was integrated into the mission. The name Almasika is derived from two Swahili words that mean diamonds and gold. “They are my most important materials, and I source them according to my principles and values,” she said. After working in communications for De Beers for 11 years, she knew where to start, and she continues to learn and refine her process.
OND: Do clients ask where the diamonds are from?
CS: Absolutely. Our clients come to us because our jewelry is meaningful in the design, the storytelling, and the materials. It is important for them to know that the materials were responsibly sourced.
OND: Where do you source diamonds?
CS: We buy from sightholders, who get their diamonds from De Beers and other known sources. When we have specific projects or requests, I source diamonds with a traceable country of origin, such as the set of flower brooches I created for Edward Enninful, featuring 17 carats of diamonds from Botswana. (Enninful wore them to the Met Gala in May.)
OND: How did you convert to only recycled gold?
CS: At first, I wasn’t sure how to source recycled gold, it took time to secure a supply chain. Five years ago, I found workshops using recycled gold, and now I have my jewelry made at these workshops in Chicago, New York, and India. It’s slightly more expensive than regular gold but it’s part of my story.
OND: Why is supporting the contemporary arts part of your mission?
CS: My husband and I collect contemporary art and believe the beauty and impact of the arts are a path for societal transformation. We support the contemporary arts in America and France. We established the SARR Prize, funded by our SARR Collection, which gives three annual awards to Les Beaux-Arts Paris students for excellence in a body of artistic work.
<She was awarded the Knight of the Order of Arts and Letters by the French government in 2022 for her commitment to supporting the arts.>
OND: Advice for other designers?
CS: Take the time to find the right sources, expand your network, and make sure they are true to your business principles.
Satta Matturi, Matturi Fine Jewelry
Everyone talks about social responsibility, but Satta Matturi lives it. “I walk the talk,” she often says. A native of Sierra Leone’s Kono region, an area rich in diamonds, Matturi uses her decades-long experience as a rough diamond expert (she worked for De Beers for 17 years) and personal connection to the African continent to inform her jewelry practices.
She puts ethics before profits, and her commitment to sourcing and craft has resonated with clients in her London home base where she has a by-appointment salon in Mayfair.
OND: Where do you source diamonds?
SM: I buy my diamonds from known sources as I have been lucky enough to have worked with some of the world’s best diamantaires, who source from miners such as De Beers, Lucara, and more, and they are fully compliant with traceable systems and other blockchain tools, so I’m assured there is provenance and best practices adopted.
OND: Why is Single Mined Origin (SMO) Gold important?
SM: My designs are mainly inspired by Africa, its culture, heritage and all its natural beauty, so I was really happy to learn of a mining initiative that ethically mined gold from African producing countries such as Senegal, Cote d’Ivoire, Mali. In 2024, I converted entirely to SMO. This really resonated with my brand values and offering. A customer that buys a piece of jewelry from us is presented with a block-chained bar code that shares the history of the where the metal was sourced.
We are also the first distributor of raw gold nuggets from Ethical Minerals, a small alluvial mining company in Sierra Leone that promotes non-toxic methods of gold extraction. They also work with local goldsmiths and artisans who craft the gold using traditional methods.
OND: Where do your colored stones come from?
SM: Colored stone sourcing is a work in progress for me, as I do not understand them as I do diamonds. While I take careful effort in sourcing from trusted partners, I have made some headway in working with suppliers such as Moyo Gems and others who collaborate and source their rough from women community mining projects in East Africa. We offer a selection of cut stones from the Moyo Gems initiative for bespoke designs created at our Mayfair showroom.
OND: Are more people asking about the source of jewelry?
SM: In this age of technology, people have instant access to information, and as a result more people are asking the right questions on where the jewelry is made, cartage, origin of stones and the like. This triggers a conversation between myself and the customer and it is an opportunity to educate and tell the story. At the end of the day, the beauty of the design grabs the consumer’s attention, but this is made much stronger when you have a compelling package and story that includes its origin and journey.
OND: What are you doing outside of jewelry?
SM: I’m passionate about youth development, so in 2020 I decided to have an outreach in Sierra Leone, my country of birth. The Matturi Sierra United Football Club was started to support young boys in disadvantaged communities through sports. I hope to establish this as a formalized Matturi foundation, which my sister and I are working on that will extend its reach into the diamond producing districts of Kono, in memory of my mother and father who worked to help local communities through the provision of basic healthcare, accessible water and artisanal skills development.
Baylee Zwart, Azlee
As an avid surfer and diver, Baylee Zwart has been acutely sensitive to man’s impact on the ecosystem, and it drives her business decisions. “As a designer, social responsibility must be part of your journey,” she said from her Santa Monica office. She sources diamonds from a vendor who buys directly from the mines and cuts the stones, and she also uses reclaimed diamonds.
“It’s an endless learning process, knowing the right questions to ask, and working to find the most trustworthy vendors,” she said. It also opens a dialogue with clients, who she says are increasingly more engaged in where their diamonds are sourced.
OND: Where do you source diamonds?
BZ: We work with an Indian vendor who can tell us the country where the rough was mined and sometimes the exact mine, and where it was cut, and we can share this with our clients. This cuts out a lot of the middle men.
Since early on in my business we have used reclaimed diamonds. It took a lot of research to find the right sources, people I could trust and know they are really vintage stones. I met a vendor who specializes in rare gemstones and unusual diamonds, and he buys deco pieces and takes them apart for the stones. Initially I was drawn to the stones for their aesthetic, the unique cuts, like the carre diamonds. Now the idea of using reclaimed diamonds is very appealing as the ultimate sustainable stone and it becomes part of a design’s story.
OND: How do vintage diamonds contribute to your pieces?
BZ: There’s a romance to the stones because they are hand-cut, unique, and have their own history and personality. Working with clients on custom pieces allows me to celebrate their unique characteristics. Using these diamonds, it is a truly one-of-a-kind piece because we know we won’t find that exact stone again.
OND: How do you engage clients on socially responsible jewelry?
BZ: We have chosen to only work with natural diamonds, so if people inquire about lab grown, it is an opportunity to speak about how natural diamonds can be responsibly sourced and educate them about natural diamonds.
OND: How do you support causes that matter to you through your jewelry business?
BZ: Since I established my company, we have donated a portion of our sales to ocean related causes because my husband and I are longtime surfers and divers, and over the past 20 years we have seen firsthand humankind’s impact on marine life. More recently we pivoted to supporting the Pasadena Humane Society and Red Cross after the L.A. fires. We lost our house in Malibu, and we are planning to rebuild, it is a process and a long journey.
Alice Herald
What makes one diamond different from the next? Designer Alice Herald says it’s the stone’s origin that determines its unique character. That’s why she makes a diamond’s birth place part of her design’s narrative and uses largely traceable stones.
“Whether it’s been tumbled out of a river mouth on the coast of Africa or formed from the deep, cold, high pressure of the Arctic crust, these aspects affect the crystal structure, quality, and resulting performance of your diamond,” says Herald, who established her namesake business in Wanaka, New Zealand.
The British native, who earned a degree in jewelry design from Central St. Martins, moved to Wanaka in 2005, a place that attracts outdoor adventurers for its majestic mountains and lakes. Since she established her business in 2016, the focus has been on enhancing the idiosyncrasies of each natural diamond.
“Natural diamonds each have their own story, their own birthplace,” she said. “The youngest natural diamonds are 1 billion years old, where else can you get access to and work with something with such history and provenance?”
OND: Where do you source your diamonds?
AH: My stones come from De Beers’ sightholders. Stones over 0.5 carats have a ‘Footprints’ certificate, which verifies its country of origin and traces it through the cutting process.
I can tell my clients where their diamond came from. It’s not only fantastic to have this traceability and transparency to add to their story but also knowing that it supports artisans miners and their communities. So much goes back into the local education, healthcare, and their growing infrastructure.
OND: What else are doing to make your jewelry responsibly?
AH: Everything is designed and crafted in New Zealand, and we use Australasian gold, where the majority comes from New Zealand.
OND: How do you personalize the diamond process?
AH: Getting to know my client and understanding the purpose of the piece helps me discover the significance of the diamond and the feel for the finished piece. One example is a ring with the two princess-cut diamonds tilted towards each other representing the couple looking in the same direction through life, and they are encircled with leaves celebrating the woman’s love of gardening.
Jessie Thomas
Jewelry was Jessie Thomas’ destiny. Growing up the daughter of British master goldsmith David Thomas, she learned the craft by his side. A highly skilled goldsmith in her own right, she creates made-to-order and bespoke pieces, and has a following for her restrained, sculptural and highly personal diamond jewelry.
From the start, the notion of conscious jewelry production was already baked into the process, something that her father had practiced for decades. That includes shaping every design at the bench and sticking with longtime vetted suppliers.
In her latest collection of diamond rings, Thomas sets the stones, so they appear seamlessly integrated into a sculptural design. The result is fluid, feminine pieces with a sense of movement.
OND: Where do you source diamonds?
JT: I am lucky to have inherited specific suppliers from my father, who has known them for a long time. I work with reputable dealers and cutters, who source from a sightholder, some stones come from Botswana and South Africa. Canadamark diamonds are from a separate source, they have specific certificates that identify the supply chain. I also have clients asking for antique diamonds.
What a client is looking for determines where I source the stones. Ideally all diamonds will eventually be blockchained from mine to retailer so we can be 100 percent transparent in the materials used.
OND: Where do you source gold?
JT: Sometimes I’ll recycle and reuse a client’s metal in the workshop, or I work with a small caster who recycles in house. I also use Fairtrade gold.
OND: How does the diamond’s story enhance your design?
JT: Every diamond is so unique and has its own characteristics. There is much more to a diamond than the 4Cs and I always want to respect this through design. I love working with clients who want to choose their stone, it’s a nice part of the process for them to see loose stones, how they differ, and find one that is special to them.
Lola Fenhirst
Standing above an immense open diamond mine in Botswana last year, designer Lola Oladunjoye envisioned her next jewelry collection. “The vast openness pulls you in and you realize how connected we are to the Earth and that we have responsibility towards it,” said the Paris-based designer whose collection is Lola Fenhirst.
Oladunjoye’s visit to Botswana’s diamond mines inspired the new PIT Series, a collection of striking gold circular concaved pieces designs with a mélange of white and grey diamonds.
“Africa doesn’t get enough credit for its treasures, mineral or otherwise,” said Oladunjoye, “and so I wanted to shine a light on the profoundly rich and diverse mineral table that lies deep within the red earth of Africa.”
The former corporate attorney turned jewelry designer draws on her Anglo-Nigerian background and West African heritage for her distinctive Lola Fenhirst designs and has made responsible sourcing integral to her designs.
OND: Where do you source diamonds?
LO: I prefer to go to the source. Finding out where everything is sourced is part of the journey; it is not as interesting to me when you buy diamonds sight unseen in a transactional manner.
For the PIT series, I’m using melee from a third-generation Indian diamond cutter who buys rough from sources that I have vetted.
OND: How are you supporting the communities where the diamonds are mined?
LO: I photographed the PIT series in Botswana to put a spotlight on the captivating beauty of the landscape and show the pieces in their natural environment, as all the diamonds used in the series were sourced from Southern Africa. I also thought it was important to support the ecosystem that has grown up around the diamond industry in Botswana by hiring models, photographers, and crew members who were all born and raised in the country.
OND: What are you doing to minimize your carbon footprint?
LO: A key tenant of sustainability is not overproducing, keeping everything small batch, so I mainly make to order. This gives clients the ability to choose the stones and make it custom. All my jewelry is handmade in our London workshop using recycled gold and diamonds that I personally select or antique stones.
OND: What’s next?
LO: In Botswana, I was amazed by the beauty of grey diamonds. I consider them to be a metaphor for the continent of Africa; they are lower in value than white diamonds and yet they are more unique, each different because they are included. I would like to find way for people look at inclusions not as blemishes but rather as a diamond’s uniqueness.
Thelma West
Thelma West, a Nigerian-born jeweler based in London who sources all her diamonds in Botswana, where she has seen the industry transform the country. “I know how diamonds and gemstones can really change lives, feeding millions of people, empowering communities,” she says.
West’s business is rooted in creating pieces that have deeper meaning and impact: She uses responsibly sourced diamonds, gemstones, and gold, and each piece is handmade by artisans whom she personally vets to ensure that the workshops who make her pieces align with her values. Rather than churning out collections, West creates contemporary one-of-a-kind pieces, each is a personal expression of the designer and wearer.
Only Natural Diamonds: Why diamonds from Botswana?
TW: Buying a piece of jewelry with a Botswana diamond is a symbol of ethical, heartfelt luxury. It supports the wonderful work done in Botswana, where diamonds are uplifting a whole country, widely benefiting those communities with increasingly sustainable extraction practices. I only work with natural diamonds, which have a much smaller carbon footprint than fake lab-grown diamonds.
OND: How do you know your gems are responsibly sourced?
TW: We have a simple and transparent supply chain, allowing us to trace the journey of every stone from its source to the final piece of jewelry.
OND: Where do you source gold?
TW: My gold suppliers have certifications, such as the Responsible Jewelry Council (RJC) or Fairmined, reflecting their commitment to sustainability and ethical practices. A significant portion of my creations features recycled gold. This is a meaningful step toward reducing the demand for new mining and minimizing the environmental footprint associated with gold production.
OND: How do you minimize your carbon footprint?
TW: I have also just started a side project which is very much around regenerative agriculture and, as part of that, we are reforesting land to unproductive woodland. That is my way to make an honest, albeit small, effort at offsetting some of my carbon footprint.
Nigora Tokhtabayeva, Tabayer
When Tokhtabayeva unveiled the Tabayer collection in Paris in 2019, she made sustainability an integral part of her vision. She’s seen the shift in the minds of consumers, saying, “They want brands with values, especially the younger generation, who are increasingly looking for brands safeguarding equitable working conditions and minimizing the impact on the environment.”
OND: Where do you source diamonds?
NT: We procure all our diamonds from recognized global sightholders who are members of the Responsible Jewelry Council (RJC). Our suppliers undergo rigorous audits and are certified by the RJC. This certification attests to their strict compliance with the RJC’s internationally recognized Code of Practices. This comprehensive code encompasses a wide spectrum of the certified member’s operations, including aspects related to human rights, community development, anti-corruption measures throughout the entire supply chain, labor rights, working conditions, health and safety standards, environmental responsibility, and the accurate and transparent disclosure of all the products they sell.
I’m working with GIA’s new ‘source verification service’ which can verify the mine the diamond rough came from. This verification will allow Tabayer to have full traceability on the diamonds we use over 0.15 carats.
OND: Where do you source gold?
NT: The gold is proudly certified as Fairmined, sourced from artisanal mining organizations with strict labor and safety guidelines that are committed to promoting social development as well as environmental protection.
OND: Where’s the jewelry made?
NT: Our jewelry is meticulously crafted in small factories (family-run businesses) that have a rich history of operating in Italy for many decades.
OND: What other groups do you support?
NT: As a woman and a mother of five, I made the deliberate choice to lend my support to two causes that hold special significance for me: Every Mother Counts is an organization that deeply inspires me with its mission to ensure safe pregnancy and childbirth for every mother, around the world, and the Period Abundance Foundation is a charitable organization dedicated to providing safe and sustainable period undergarments to those in need.
OND: How do your personal values influence your jewelry design?
NT: Growing up in Uzbekistan, I was deeply immersed in a culture where jewelry held significant spiritual significance, functioning as protective amulets, and this had a profound impact on me. To me, jewelry transcends its role as mere embellishments or ornaments. I wanted to create pieces that can grant their wearer the spirit of autonomy and self-determination. Tabayer pieces are modern amulets to make anyone who wears them feel empowered to achieve what they set their mind on.
Emily P. Wheeler
To ensure she’s doing everything possible to create sustainably sourced jewelry made in ways that benefit all the hands that touch the piece, Wheeler hired a sustainability coach to help her develop a Supplier Code of Conduct for all her partners. That ensures she’s creating jewelry that is beautiful and that you can feel good about.
OND: Where do you source diamonds?
EW: I source as much repurposed melee and large diamond cuts as I can, including antique and vintage stones.
OND: How do you ensure your diamonds and gemstones are responsibly sourced?
EW: I’ve been working for years with trusted suppliers that I vet myself or that are RJC members. With larger stones, it’s also easy to tell if something is authentically antique based on the cut.
OND: Where do you source gold?
EW: I have used recycled and Fairmined gold and am moving towards Single Mine Origin gold for 100% of the collection.
OND: What philanthropic groups do you support?
EW: We donate approximately $20,000 or more of product towards fundraising initiatives each year. In the past, that has been towards animal rights groups, Boys and Girls Club of America, NAACC, and the Marfan Foundation.
OND: How does your philosophy impact your jewelry?
EW: I don’t design with materials that I believe to be irresponsibly sourced; I look for alternatives to gold and I use antique stones.
Erin Sachse, founder of Eriness
“The morals and values I uphold for my personal life are the same as the ones I have for my business,” says Erin Sachse, the Los Angeles-based designer. She lives and breathes that mantra, even when it means spending more time and money to find the partners that align with her values.
OND: How do you ensure your jewelry is responsibly sourced and produced?
ES: When I began the process of finding a production team, it was important to me that I worked with a team that cared about sustainability, safe practices, conflict-free materials, and of course, impeccable workmanship. The team we work with is a member of the RJC, which ensures supply chain integrity from start to finish.
OND: Where do you source diamonds?
ES: All of our stones are certified as conflict-free and verified with the Kimberley Process and the System of Warranties (SoW) Guidelines. I am proud to create beautiful products that morally align with my beliefs and are ethically sourced.
OND: Where do you source gold?
ES: We’ve been sourcing conflict-free gold with the same company out of New York for over eight years.
OND: What other groups does your jewelry support?
ES: Channeling my belief that Eriness can do more than just sell jewelry, we donate proceeds of the Resist collection to the ACLU, Color of Change and Planned Parenthood. It’s easy to feel helpless in today’s political and social climate and I think however small this is, it feels like you can do your part.
OND: How does your philosophy impact your jewelry design?
ES: For me, jewelry is not a one-time wear. It’s something you have forever. Something you pass down to loved ones and something that tells a story. The jewelry I design reflects my love of nature, simplicity, and spirituality.
