Shop by stone

Start with the colour. Most of our designs are made in more than one stone, so each stone below opens everything we make in it, and the stone itself is chosen on the product page.

The stones shown here are colour references, not photographs of individual pieces — every listing shows the piece you would actually receive. Where a stone is treated to bring up or steady its colour, we say so. Treated is not the same as lab-grown, and neither is the same as simulated glass.

A note on treatment

Treated does not mean fake. A treated stone is a natural stone that has been heated, irradiated, dyed or stabilised to bring out or steady its colour. It is normal, it is extremely common across the whole trade, and the result is permanent in ordinary wear. What it is not is lab-grown, and it is certainly not simulated glass.

Some specifics, so you know what to expect. Almost all blue topaz on the market, ours included, is irradiated and heated to produce the blue; the result is stable, though topaz has a basal cleavage that makes it worth protecting from a hard knock. Most citrine is heat-treated quartz. Black onyx is commonly dyed. Garnet and peridot are generally untreated. Opal is porous and wants gentler cleaning than the rest.

Amethyst holds its colour well in ordinary wear, though prolonged exposure to strong light can fade some material over time — worth keeping in mind for a piece you leave on a sunny windowsill rather than in a box.

We say what we know, because you should know what you own. If you want to ask about one specific piece, write to us.
