Chrysoberyl (sixling twin circa 1940s)
Thumbnail, 2.4 x 1.9 x 1.9 cm
Itaguacu, Espirito Santo, Brazil

Some of the most classic Chyrsoberyl specimens in the world are those from Espirito Santo in the southeastern end of Brazil. This thumbnail, with fine, yellow-green color, excellent luster, and good gemminess, has the most recognized and celebrated habit for Chrysoberyl - the "sixling" twin. This deposit only produced from 1939-1941, so this crystal is a rare, and highly sought-after, specimen. It is a "Classic," with excellent aesthetics and style right out of the old books. Rare on the market, this is from two major thumbnail collections in the last few decades. 15 grams mass.
