13.08 ct Blue Topaz-Blue - Heart

At 13.08 carats, this topaz from Brazil carries its blue color through a heart cut, measuring 15.5 x 15.5 x 9.1 mm.

Topaz is a hard, brilliant gem species; its blues are the best known, but it runs from colorless through the coveted imperial oranges. Brazil has been one of the most prolific colored-gemstone sources in the world for a century, and still turns up new material on a regular basis. Its color was brought up by irradiation, a standard and fully disclosed treatment for this material.

This is a center-stone-grade gemstone with a character of its own, chosen rather than settled for. Hand-selected and photographed by Caveman Gems in good light, shown as honestly as a screen allows.
