Checkerboard Cushion Swiss Blue Topaz Stud Earrings

A 6 mm cushion of Swiss blue topaz, cut with a checkerboard crown — a grid of small facets across the top face instead of one broad table. The effect is a stone that flickers rather than flashes, catching light from more angles as you move.

Swiss blue is the middle of the three blue topaz colours: brighter and more saturated than Sky, clearer and livelier than London. Each stone sits in a double claw-prong head, which spreads the bearing load across two contact points per corner instead of one.

A gift that means something. A December birthday, or a fourth anniversary, in the size people actually notice.

About this gemstone. The blue colour of topaz is created by treatment. Each stone here is genuine, mined topaz that has been irradiated and then heat-treated to develop its blue colour — this is how virtually all blue topaz on the market is produced. The colour is permanent and stable in normal wear, and will not fade with ordinary use. “Sky Blue”, “Swiss Blue” and “London Blue” are trade colour descriptions, not separate gem species or geographic origins.

Caring for topaz. Topaz has perfect cleavage in one direction and can chip or split from a sharp knock. Do not clean it in an ultrasonic or steam cleaner — warm soapy water and a soft brush only.
