Rough Diamond Evaluation in Sandton
Selling a rough diamond parcel without an independent evaluation means negotiating on the buyer's terms. We assess weight, colour and yield potential before you talk price with anyone.
An honest number for rough stones
Rough diamond value depends on weight, colour, shape and estimated cutting yield, and most sellers only have an estimate rather than a proper assessment. That gap is exactly where buyers negotiate a lower price.
We evaluate rough diamond parcels at our Sandton offices, giving you a documented valuation and Kimberley Process status check before you agree to sell to anyone.

Common questions
Do I need Kimberley Process certification before the evaluation?
No, but we'll confirm certification status as part of the process, since it affects what you can legally do with the parcel afterwards.
How is cutting yield estimated?
Based on the rough stone's shape, inclusions and size, assessed against typical yield patterns for similar rough.
Do I have to sell to New Age Global afterwards?
No. You're free to take the valuation and negotiate with any buyer.
