Crisper than most of the 10x8mm ovals, this 3.10ct stone has sharply drawn facet junctions and real contrast between the bright planes and the darker blue between them, so the pattern reads clearly rather than blurring. A fine white feather sits low on the left side, catching light as a pale flash at certain angles and consistent with the VS grade. The color is a clear medium sky blue. The oval is well proportioned and brightly polished.
Contrast is what separates a lively oval from a flat one, and it comes down to how accurately the pavilion facets meet. This one was cut with care. Brazilian rough irradiated and then heated is the source of all sky blue topaz. At just over 3ct the stone carries a ring or a pendant equally well. Blue topaz is one of the stones December claims.
Natural sky blue topaz, 3.10ct 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.
