RapNet

Rapaport’s Green Star Source Program highlights diamonds that meet high ethical and environmental sourcing standards. It provides transparency and builds trust between buyers and sellers, while promoting responsible practices across the diamond supply chain.

The Green Star designation currently applies to polished diamonds that meet both of the following criteria:

Rough Source: Diamonds must be sourced from:

- Okavango (Botswana)
- DTC (Botswana, Namibia, Canada, South Africa)

Certification: Must have a GIA Diamond Origin Report (DOR)

1. Rough Source: Diamonds must be sourced from:

How Green Star Diamonds Display on RapNet

Green Star diamonds are marked with a green star icon in both the search results and the diamond item page.

You can also filter specifically for Green Star diamonds on the search engine.

Note for Sellers If your diamond meets the criteria, RapNet automatically applies the Green Star symbol—no extra steps needed!

Due to global sanctions, particularly on Russian-origin diamonds, RapNet has added rough source transparency tools.

Sellers can now indicate the country or mine of origin when uploading diamonds.
