Pink crystals of Smithsonite on a dark sulfide matrix. Exceptionally well colored vivid crystals.

Azurite crystal cluster composed of a major 2.1cm crystal with smaller crystals, some of which are altering to Malachite. The Azurite has bright 'electric' blue color.

Lovely rosettes of Azurite from the famous Chessy mines of France. These mines are long closed and I understand these specimens were found in the 1800s. This specimen is composed of two attached clusters of gorgeous blue color. There are no points of contact, a complete floater and undamaged.

Interesting bi-color Tourmaline from  Mwajanga, Tanzania.  The crystal is a transparent, deep rootbeer color in the lower half with a sharp change to silvery grey, cat's-eye at the top. These half normal/half cats-eye crystals were found once at this mine and are very distinctive. This is a good sized crystal from this find. Weighs 16.3 grams.

Hackly Copper protruding out of a Quartz matrix with areas overgrown by clear Calcite crystals. Well balanced specimen with lots of Copper and good coverage of Calcite crystals heavily included by bright, non-tarnished Copper. There is some damage to the Calcite, but it is in overall good condition.

Thick, deep forest green Brochantite crystals with high luster on matrix. Two very fine, well isolated clusters stand out against the lighter colored matrix. Largest cluster is 2.7cm wide. Individual crystals reach 7mm in width. These are thick, robust crystals from a 2014 find and are much different in style than earlier finds from the mine which were usually more fragile, hair-like crystals.

Thick, deep forest green Brochantite crystals with high luster on matrix. Loads of fine terminated crystals. These are thick, robust crystals from a 2014 find and are much different in style than earlier finds from the mine which were usually more fragile, hair-like crystals.

Thick, deep forest green Brochantite crystals with high luster on a thin wafer of matrix. Main crystal is 6mm wide. Good crystals on the bottom side too. These are thick, robust crystals from a 2014 find and are much different in style than earlier finds from the mine which were usually more fragile, hair-like crystals.

Large single Azurite crystal with Malachite and smaller attached Azurite crystals. Superb electric blue coloration and wet luster. The frontside has a couple rows of tiny Azurites attached, and the backside has a single larger Azurite coming out the face. This grew straight out from the pocket wall giving such beautiful 360 degree viewing. There is a natural notch along the top edge and there appears to be a little damage right in the notch. Otherwise this is perfect and even stands up on it's own.

Single, terminated Azurite crystal on velvety, botryoidal Malachite. The Azurite is 1.5cm long. Specimens such as this are uncommon from Milpillas and are highly attractive.

Choice minature of 3 Azurite crystals to 1cm on Malachite. The Azurite crystals have superb color and luster and are undamaged.
