💎 Loose Diamonds

  • 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.

💍 Mounted Jewelry 

  • 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.

⚠️ Important Notes & Limitations 

  • 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.
