About
The price-discovery layer for lab-grown diamonds.
Natural diamonds have a trusted benchmark the whole trade prices against. Lab-grown doesn't. Its pricing is volatile, fragmented across dozens of supplier feeds, and has no index — so every buyer is quoting blind.
StoneOS is the aggregation layer that fixes that. We pull every supplier's live lab-grown inventory, normalize it into one canonical schema, and expose it as a clean, keyed API plus a terminal — with true cross-supplier price discovery and transparent sourcing on top. Wholesalers, retailers, and developers build their storefronts, pricing tools, and procurement on it.
We're not a marketplace bolted onto a natural-diamond benchmark. We're lab-grown-native infrastructure, built API-first.

What we stand for
Aggregation over fragmentation
The lab-grown market is dozens of suppliers, each with its own feed and prices. We normalize them into one canonical, comparable source.
Price discovery, not a listings board
For an exact 4C spec we show the best price, the spread, and the median $/ct across suppliers — the number the market is actually trading at.
API-first and transparent
We're infrastructure others build on, with an explicit shown platform fee — not an opaque trading network you have to phone.
