About

A quieter way to buy colour.

Natural sapphire, ruby, spinel, tourmaline and emerald. Treatment and origin are written as they are. Prices include UK VAT. The twelve stones here are sample figures, not stock.

The studio

A small London cabinet. Fewer stones, and the facts that change a price kept in one place: gem, colour, origin, treatment, weight and measurements.

There is no published street address. Viewing is by appointment, once a stone is real stock rather than a sample on this page.

What we sell

Treatment is unheated or heated. Emerald may carry minor colourless oil. Oil is traditional, and it can dry out. That is written on the stone, not added after a sale.

Origin is a country when the stone supports it. A mine is not invented. A Mozambican tourmaline is not called Paraíba. Colour is described in ordinary words, not a trade grade.

What we do not sell

No beryllium diffusion. No glass filling. No resin or polymer in an emerald. No badly cracked stones, no chips on the girdle, and no flat cuts that window the colour out of the centre.

A laboratory report is either absent or, in this catalogue, marked “Sample — not a real report”. Report numbers are not invented.

Price

One price, in pounds, including UK VAT. Checkout charges that amount. Tax is not added on top, and delivery is not added in the cart.

Weights, measurements and prices on these twelve stones are sample figures, so the shop can be used. The drawings are illustrations, not photographs.
