Minimum size: Greater than 0.1 carat

Tray usage:

• Divided tray: Place one diamond per square.

• Undivided tray: Ensure stones are separated and do not touch each other.

Best practice: Place diamonds table-down for optimal results.

Minimum mounted stone size: Greater than 0.25 carat

Supported jewelry types:

• Simple designs only, such as solitaire rings or stud earrings.

• Stones must not touch each other.

Placement: Ensure stones face upward for accurate detection.

Detection misses:

• Occasional misses may occur, especially in jewelry.

• If a stone is not detected ( not painted by the AI model) , slightly adjust the piece and run the test again.

False positives:

• The AI may occasionally mark non-stone areas (metal parts or reflections).

• These markings should be disregarded.

Detector vs. AI accuracy:

• Yehuda detectors will not miss a lab-grown diamond when verified by a human decision.

AI accuracy:

• Currently over 99%, but the model is still learning and improving.

Note:

• The AI model serves as an advisory tool, not a final authority.

• Continuous updates and training will further enhance its performance.
