The pavilion of this sky blue topaz throws a clear star of light back up through the table, which is what makes the 9mm trillion outline read so lively. The blue is a medium, faintly cyan-leaning tone, even from corner to corner, with no zoning and full transparency. A few tiny dark pinpoints sit near the center, consistent with the VS grade, and a small nick on the girdle at one corner is fully covered by a claw. The triangular shape gives the stone more spread than a round of the same weight.
Brazil is the source of nearly all sky blue topaz on the market: colorless rough is irradiated and then heated, which locks the blue in permanently. Trillions of this size are a favorite for pendant drops and for ring designs where the three corners can be echoed in the setting. Blue topaz is one of the modern birthstones for December, so it makes an easy gift for winter birthdays.

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
This topaz is 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.
