Three pale blue squares at 3mm, cut as step squares rather than brilliants, so each one shows a clean pyramid of light rising to a small central point instead of a scatter of flashes. The tone is a soft even sky blue and all three match closely. Clarity is VS with clear interiors. Corners are sharply formed and the steps are cut parallel on every side.
Square step cuts at this size are used in geometric and Deco-styled work, set in rows or blocks where the straight edges line up against the metal. Brazilian topaz reaches its blue by irradiation followed by heating. Three matched stones give a maker a short run without buying a full parcel. Blue topaz is one of December's birthstones.
Natural sky blue topaz, set of three 3mm squares, sold together.

About topaz
Topaz is 8 on the Mohs scale, so it resists scratches well, but it has perfect cleavage along one plane, and a sharp knock can split it even when the surface shows no scratches. It suits pendants and earrings, and rings too if worn with care.
Cleaning
Warm water, a drop of mild dish soap and a soft toothbrush are all you need. Brush behind the stone too, where dust and skin oils collect, then rinse and dry with a soft cloth. Skip ultrasonic and steam cleaners: vibration and sudden temperature changes can start a crack along its cleavage.
Wear and storage
Take it off for sport, gardening or heavy work: a sharp knock can split it. Harder stones such as sapphire, ruby and diamond can scratch it, so store it on its own in a gem jar or a soft pouch.
For your jeweler
These stones are irradiated, the usual treatment for this color. Topaz should be kept away from the torch flame, acid pickle and the ultrasonic bath. Ask for gentle pressure when setting, since a hard push can split it.
