Summary

Description
English: Beryl (Var.: Morganite)
Locality: Araçuaí, Jequitinhonha valley, Minas Gerais, Southeast Region, Brazil (Locality at mindat.org)
This stunning, unique gem morganite specimen was released from the personal collection of a Brazil-based collector/dealer who was able to cherry-pick specimens from the prolific production out of Minas Gerais over the years. It was by far the most unique specimen I found at the show, and is just incredibly striking. Two flattened, hexagonal gem morganite crystals have grown side-by-side, and inside each of them is a sharp, hexagonal phantom ROTATED ON ITS AXIS by 30 degrees or so from the crystallography of the enveloping morganite! The faces on the bottom and back right side of the specimen are slightly incomplete due to removal from the pocket, but as you can see, the specimen can be displayed to minimize this and really you don't see the slightly rough rear-right edge anyhow. Just one crystal like this would be fascinating, but this piece consists of TWO matching crystals that formed side by side under the same unique pocket conditions, showing the same phantom growth inside with the same rotational offset! I have never seen anything quite like this, in ANY species. 4.8 x 3.4 x 1.7 cm
