Oval Blue Sapphire
global trade
A trade desk built by people
who know the trade.
Most pricing tools stop at Rapaport. We start there — then layer in real Market ex-works data, manufacturer premiums, lab differentials, and negotiation behavior. That's what makes a valuation actually usable.
Valuations that match reality
Six-layer pricing pipeline — Rapaport, quality adjustment, manufacturer premium, market discount, negotiation, export margin.
- Naturals, LGD & colored stones
- Certificate OCR for GIA, IGI, GCAL
- Dual pricing: ex-works + platform
Live market intelligence
See what diamonds and colored stones are actually trading at — aggregated from Market bourses, RapNet, VDB and verified partner feeds.
- 3-minute refresh cycle
- Historical prices back to 2020
- RAPI index tracker built-in
Inventory & trade tools
List, match and move parcels with verified counterparties. Every stone is tied to a live valuation and a certificate of provenance.

- Anonymous partner matching
- Escrow and compliance built-in
A pricing engine
tuned to Market.
New York quotes Rapaport. Antwerp quotes Rapaport. But no diamond actually trades at Rapaport. We anchor to where stones really change hands — and tell you exactly how far from the list price you should be.
Anchored in ex-works data
110-cell base price matrix calibrated against live Market ex-works levels — not theoretical list prices.
Six-layer pricing pipeline
Rapaport baseline → quality adjustment → manufacturer premium → market discount → negotiation → export margin.
Dual pricing layer
Every stone returns both a Market ex-works price and a platform price — so you see exactly where the margin sits.
Built for naturals and LGD
HPHT/CVD growth-method premiums, IGI/GIA/GCAL/SGL lab differentials. 35,000+ validated training rows.
Prices that move
with the trade floor.
Every price you see on Gemfinity is a live composite — drawn from Market bourses, RapNet, VDB, and verified manufacturer feeds. Refreshed every three minutes, archived back to 2020.
