- Receive a stone on memo — no planning documentation
- Trust the certificate but can't verify the cutting process
- No visibility into origin, yield, or how angles were decided
- Customer asks "where is this from?" — you don't have the full answer
- Search a live inventory — filter by carat, color, clarity, shape, origin
- Every stone has a Sarine planning report before the first cut
- Crown 34.5° ± 0.2° — locked specifications, verified process
- Full provenance: mine → scanner → cutter → GIA → you
- Customer asks — you show them the entire journey and documentation
Real stones. Real specs. Ready to quote.
Five steps. Full documentation at every one.
Rough Diamond Sourcing
We acquire 3ct+ rough diamonds through our DMCC-licensed supplier network. Every stone is selected for its potential before entering the pipeline.
3D Scanning & Planning
Each rough is 3D-scanned with Sarine. The system maps inclusions, predicts light performance, and calculates the optimal cutting plan before any facet is cut.
Cutting to Locked Specs
The cutting plan is locked — crown angle, pavilion depth, table percentage, all to ±0.2° tolerance. The cutter follows the Sarine plan exactly.
GIA Certification
Every finished stone is submitted to GIA. Color, clarity, cut quality — independently verified. The certificate confirms what the Sarine plan predicted.
Stone + Complete Documentation
You receive the finished diamond with its entire story — Sarine report, GIA certificate, cutting specs, origin chain. When your client asks, you have the answer.
The difference between buying a stone and knowing exactly what you're getting.
Sarine is the industry's leading diamond planning technology. It creates a 3D model of the rough diamond, maps every inclusion, and calculates the optimal cutting plan — before a single facet is touched.
For you, this means: the specifications you see in our inventory are not post-cut measurements. They're the specifications the stone was planned and cut to achieve.
The result: higher consistency, fewer surprises at certification, and documentation you can share with your clients to show exactly how their diamond was made.
Every stone comes with its complete story.
The numbers behind the desk.
