Details
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.

Answers, before you ask
Your Questions
Q: What is a trillion cut?
A: A triangular brilliant — three sides, faceted for sparkle rather than step-cut. It is an uncommon shape and reads very differently from a round or oval stud.
Q: Are the halo stones real diamonds?
A: Yes. Natural diamonds, G-H colour, 15 per earring in a single continuous row. One eighth carat total weight (1/8 ct tw) is the weight for the PAIR, which is how the trade quotes earrings.
Q: How big are they?
A: The trillion measures 5 mm on each side, and the finished halo stud is about 7 x 7 mm.
Q: Does the halo do anything besides look good?
A: It does. A trillion's three corners are its most fragile points, and the diamond row sits proud of them, so the halo takes a knock before the corner does.
Q: Is the blue colour natural?
A: The topaz is genuine mined topaz, and its blue colour is created by irradiation followed by heat treatment. That is how essentially all blue topaz is produced, and the colour is permanent and stable in normal wear.
Q: How should I clean these?
A: Warm soapy water and a soft brush. Never use an ultrasonic or steam cleaner — topaz has perfect cleavage in one direction and can chip from a sharp knock.
