Bolivia

One deposit.
Two colors in every stone.

Natural ametrine, cut to order and supplied wholesale to lapidaries, designers and gem houses worldwide.

Most colored stones in the trade pass through dozens of possible sources. Ametrine does not: every stone comes from a single deposit in Bolivia, the only place on earth where this bicolor material is mined commercially.

That is not a marketing frame, it is a supply fact. One origin means one story, one chain of custody and the same gemological footprint in every lot we ship, year after year.

Where it comes from

Santa Cruz, Bolivia.

The deposit sits in the lowland forest of Santa Cruz, near the Brazilian border. It is remote, it is worked by hand, and it is the only commercial source of this material in the world.

Category A Only

One grade. No mixed parcels.

Everything we supply is Category A. We do not blend lower grades into a lot to fill an order. Rough is hand-selected before it reaches the cutter, and each stone is faceted by hand to hold the color division exactly where the design calls for it.
