Gems
Faceted and cabochon stones, single pieces, matched pairs and suites.

Correctly named
Species and variety under their proper names. Paraíba means copper confirmed by chemistry, padparadscha means the defined colour range — not something that resembles them.
Stated, not implied
Weight, origin where we can support it, and treatment in the honest form. Where a laboratory report exists it is shown, including the inconvenient parts.
The working shown
A reference hub for every stone we deal in: chemistry, colour, properties, origins, history. The same knowledge we buy with.

What we doHow we work
Wholesale supply, single commissions, and cutting to order
Wholesale and trade
Coherent parcels, matched pairs and suites, calibrated goods, repeat supply of a single colour — cut stones and rough alike.
One stone for one piece
A private commission sourced to a brief, with the faults named alongside the merits, and an honest answer when the budget and the stone do not meet.
Cutting to order
From our rough or yours. Orientation set for colour rather than for the weight it saves, plus recuts and calibrated sizes.

What “heated” means on a listing
Almost all tourmaline on the market has seen an oven. That is not a scandal — but silence about it is.
Why darker is not better
Buyers trained on sapphire and emerald reach for the deepest stone in the tray. In tourmaline that instinct costs money.
Paraíba, or a very good blue tourmaline?
The price gap between the two is a factor of a hundred, and almost nothing you can do by eye will close it. Here is what the eye can do, and where it has to stop.
