Diamonds Eligibility

Diamonds submitted to grading labs to be graded through GIS need to be:

  • Loose natural diamonds.

  • D-to-Z colour.

  • A polished diamond with a valid Tracr ID. A diamond marked as deleted in the inventory is not eligible for GIS.

  • A polished diamond with an attached, valid polish diamond measurements report. Please refer HERE.

Validating Tracr IDs

All Tracr IDs are CUID2 ids.

Match pattern:

^[a-z\d]{20,98}$

GIS does not support fancy colour diamonds.
