Trillion Swiss Blue Topaz Stud Earrings with 1/8 ct tw Diamond Halo

A trillion — a triangular brilliant cut — of Swiss blue topaz, ringed by a single row of natural diamond, 15 stones to each earring (1/8 ct tw for the pair). The triangle is the point of this piece: it is a shape almost nobody carries, and it reads instantly different from a room full of round studs.

The halo earns its place structurally as well as visually. A trillion has three sharp corners, which are the most vulnerable points on any faceted stone; the diamond row sits proud of them and takes the knocks first.

A gift that means something. A December birthday or a fourth anniversary, for someone who already owns the round pair.

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.
