Hyalite Opal Crystal Specimen - Zacatecas, Mexico - Intensely UV Reactive - 19.7 ct.

Gem:  Hyalite Opal Weight:  19.7 ct. Dimensions:  20 x 16 x 14 mm Clarity:  N/A, but very clean - Surely some facet rough inside, but better as a specimen Origin:  Zacatecas, Mexico Treatments:  none Comments: This opal is just right!  The interesting part of the specimen is a large chain or cluster of blobs, that has just a very small amount of iron staining, which actually helps add depth, and define the botryoidal surface texture.  This large bit of crystallized opal sits nicely on a chuk of matrix.  This one displays 360 degrees, and shows a vivid green glow under UV light.  Whats not to love??
