20.80 ct Blue Topaz-Blue - Pear

At 20.8 carats, this topaz from Brazil carries its blue color through a pear cut, measuring 21.6 x 15.8 x 10 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.

No two of these line up the same way on color, cut, and origin at once, which is what makes choosing this one feel deliberate. Hand-selected and photographed by Caveman Gems in good light, shown as honestly as a screen allows.
