Description

A superb azurite specimen from a unique find that was made in 2017. These were by far, the best azurites that we have ever seen from Greece. This is an excellent example with gemmy, well-formed, highly lustrous crystals of blue azurite, associated with white to colorless calcite, green sprays of malachite and darker green brochantite. The main crystal is doubly-terminated and on a little bit of gossan matrix!
