Diamond Screening Process

All screened diamonds identified as natural are sealed in tamper-proof packets. If any diamonds are found to be other than natural mined diamonds (e.g., lab-grown or synthetic stones), they are separated and placed in a red color labeled packet alongside the natural diamond packet. This ensures proper screening and segregation.

In certain cases, a few diamonds may be placed in a "Refer for Further Testing (RFT)" packet. These require additional analysis using a separate machine to determine possible treatments or to verify if they are natural Type IIa diamonds.

Screening Steps:

1. Weighment (Initial):
   Customers are requested to weigh their packet in the presence of the gemologist before submission.
2. Cleaning:
   All diamonds are cleaned prior to the screening process.
3. Screening:
   Diamonds are screened using advanced technology machines.
4. Segregation: If any lab-grown or synthetic stones (e.g., Moissanite or Cubic Zirconia/A.D.) are detected, they are separated and placed in a clearly labeled packet.
5. Refer to further Test (R.F.T.) Diamonds that cannot be detected using screening machines and require further analysis are placed in the RFT packet for advanced testing.
6. Weighment (Final):
   After screening and segregation, diamonds are re-weighed by the customer to confirm the receipt and accuracy of the process.
7. Non-Tearable Packaging: Natural diamonds are returned in the original packet provided by the customer. Any non-natural diamonds are returned in a separate packet labeled in red color. All packets are sealed together in a single non-tearable recycled plastic bag to ensure accuracy, security and transparency.
