Strong horizontal banding defines this 1.90ct octagon, with alternating light and dark steps running the full length of the stone and a bright open center held between them. The blue is a clear, even sky tone that holds the same value from end to end. A single small rounded inclusion sits toward the right side, visible on close inspection and in line with the VS grade. Cutting is tidy, with clean junctions and matched corners.
There are several 8x6mm octagons here cut from the same parcel, so a matched pair or a graduated row can be put together from stock rather than ordered specially. Brazilian topaz is irradiated and then heated to reach and hold this blue. The calibrated size means no setting work beyond the ordinary. December birthdays are covered by blue topaz.
Natural sky blue topaz, 1.90ct octagon, 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.
