    Instrument Capabilities

    Automated Feed: Yes

    The user loads up to 500 carats of loose polished stones into the AMS2 in a specific size range. The instrument then automatically processes the stones and dispenses them into their respective category.

    AMS2 dispenses the stones into four categories:

    1. Pass (i.e. diamond)
    2. Synthetic
    3. Non-diamond
    4. Refer

    ‘Refer’ could indicate potential synthetic diamonds and diamonds. The referrals should be tested further for full verification.

    AMS2 needs to be calibrated periodically.
