A double terminated Aquamarine crystal perched atop Albite and Muscovite. There is a thin layer, just below the surface, in the middle of this crystal, which is an orangish color. The rest of the crystal is a rich blue color which is most noticeable when viewed from either end of the crystal. The Aquamarine crystal is well formed and composed of smaller, merged, parallel crystals The crystal is for the most part opaque but becomes translucent on the ends with a thin layer at one termination which is transparent and colorless. The Albite has a complex surface and is off white in color. The Muscovite crystals are gray in color and well formed. There is a thin layer of micro crystals of an undetermined material covering the sides of the Muscovite crystals which gives then a matte surface. The ends of the Muscovite crystals do not have this coting and have a high luster.

Condition: Very Good

Flaws: Nothing Appreciable
