Pale and icy at 10x8mm, this 3.14ct oval returns a good deal of light for so light a color, with bright white flashes running across the upper crown. A fine dark line sits just right of center, and there is a small nick on the girdle at the lower right with a lightly frosted patch beside it, both sitting where a claw or bezel rim covers them. The blue is even from end to end. Clarity is VS.
Ten by eight millimetres is the size most often specified for a statement oval, standard enough that settings are easy to source. Brazilian topaz is irradiated and then heated to reach its blue permanently. A pale stone benefits from an open-back mount, which lets light in from behind and lifts the color. Blue topaz is a December birthstone.
Natural sky blue topaz, 3.14ct oval, sold loose.

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.
