Carbonera Mine, La Trinidad, Tequisquiapan Municipality, Queretaro, Mexico
51mm x 30mm x 15mm
Unusual locality for this sort of opal that looks very Australian. The Carbonara mine in Mexico has produced mostly a reddish "Fire Opal" but small amounts of precious Opal with a milky white base have been found over the years. This piece has quite good fire with red, green, blue and some orange color flashes.
No-one has added this to their favourites.
