LA13 - Opal - 580€

This specimen of "tridymite crystobalite opal" is out of a unique pocket of crystallized opal that was opened in spring 2014. While most of this mineral is for cutting only, this pocket provided the market with a limited amount of crystallized botryoidal opal. This specimen shows most intensive turquoise blue color in contrast to some white zones and orange limonite cumulated betweent the opal "grapes". There is some damage present but as this specimen is one of only a few pieces, this has to be acceptable. This is a extremely rare collectors specimen of Opal-CT!

SR747 - Azurite - 3500€
Milpillas Mine, Cuitaca, Mun. de Santa Cruz, Sonora, Mexico

A killer azurite from the Milpillas Mine! This dark and mysterious crystal is 4.4 cm long and 2.2 cm in diameter, sitting on a small white piece of matrix. The azurite is sharply defined, a doubly terminated crystal of excellent luster and surface structure. The inside is very dark but with some gemmy patches near the surface that are sparkling indigo blue in direct illumination! The specimen is in very good condition. It has only one very small chip worth mentioning on the upper termination but is apart from that perfect and really a mesmerizing specimen!
