Specimen ID: WKP-DXF

Opal : SiO2·nH2O
As recorded:
San Luis Potosi, Mexico
Mindat locality:
28mm x 26mm x 21mm
A rather gemmy, soft golden orange color, lustrous, globular group of â??Blood Vessel Opalâ? / Hyalite Opal featuring a group of intergrown â??spheresâ? which get their color from tiny inclusions of iron oxide. A little below the surface, the specimen shows the thin â??capillaryâ?-esque lines that give it such a unique appearance. One typically does not see Hyalite Opal of this quality and color on the market. Only a tiy bit of damage on the back, and attractive to be sure.
