Beryl Var. Aquamarine (Cesium included)

ID: 6289
Add to OrderNot checked

During the summer of 2012, a small lot of the deep blue aquas appeared on the market and were thought to be Vorobyevite. After analysis by Dr. Federico Pezzotta in Milan, they were confirmed to be a cesium included beryl, but not rich enough to be vorobyevite. Most of the crystals found were under 2.5 cm wide, so this one would be in the top percent for quality color and crystal size (3.4 cm!). No more have been found.

Beryl Var. Aquamarine (ex Nelson Coll.)

ID: 3450
Add to OrderNot checked

A group of approximately 12 medium blue crystals that run from milky to gemmy, of the aquamarine variety of beryl, in parallel growth forming a divergent spray with textbook, complete terminations. There is one small broken crystal which prevents it from being a 360 degree rock, but as you can see from the photos, this miniature displays beautifully and is actually a good companion to the indicolite (no. 3449). Choice!

Beryl Var. Aquamarine on Quartz (ex Nelson Coll.)

ID: 3170
Add to OrderNot checked

A very unusually zoned aquamarine crystal with an exceptional termination and a cloudy core that forms a hexagonal outline within the crystal. As you can see, the beryl is cloudy up until the termination, drawing a very distinct line and then becomes of faceting grade. This wonderful crystal sits on a matrix of quartz, feldspar and a smaller beryl on one side. Super!
