Cut & Polish
Turning mine rough into polished diamonds — matched to buyers who know what they need.
Cut for yield and fire
Rough is only the beginning. Our sorting and analysis decide how each diamond should be cut — maximising yield, brilliance and market fit. Tradition guides the hand; modern tools sharpen the outcome. The result is a polished stone ready for trade or setting, matched to the buyer who needs it.
Triple 7 treats cutting as mining's next step: protect the stone, unlock the light, and deliver a polished diamond ready for the Trade Desk or a jewellery setting.
Our process

Sorting
Rough is graded by size, quality and potential before any cutting plan is locked in.

Stone analysis
Structure, inclusions and yield drive the cut — so beauty and carat are balanced for the market.
03
Precision cutting
Experienced cutters use modern tools to open the stone — facets designed for brilliance and lasting value.

Polishing & finish
The diamond leaves the wheel ready for trade or jewellery — clean, consistent and buyer-ready.
