Opal (var: Opal-AN) / (var: Hyalite Opal) (“Blood Vessel Opal”) metamorphic The base of the Goethite

The base of the Goethite “stem” can be seen protruding from the underside of the specimen

I love the triangular shape of the upper portion of the piece

Vauxite is still only found in one locality in the world

the piece is essentially damage free and is an aesthetic representative specimen from this classic discovery

Opal (var: Opal-AN) / (var: Hyalite Opal) (“Blood Vessel Opal”) metamorphic The base of the GoethiteOne of the most lustrous pieces in the update. Highly glassy beads of gemmy, orange to nearly colorless Hyalite Blood Vessel Opal from this new find in San Luis Potosi, Mexico. The inclusions are created by iron oxide and give the piece wonderfully strong red orange coloration and thin capillary like lines where the nickname Blood Vessel Opal comes from. A tiny bit of attached matrix makes for a great overall piece, and a worthwhile pickup for anybody
