A superb, complex gemmy and lustrous twinned crystal of calcite sits on a tan limestone matrix. These are some of my favorite calcites. Almosta 360 degree specimen.

A pair of compact rosettes of azurite crystals with a medium deep blue color resembling a pair of bushes (for lack of a better description). A superb floater.

An umber colored scheelite crystal sits alongside a trio of intergrown purple fluorite cubes on a dolomite and tiny scheelites matrix and topped by a group of brassy chalcopyrites. Choice miniature.

Sharp and lustrous lime green crystals of cuprian smithsonite coating a white calcite matrix. Pretty rock!

Wonderful euhedral crystals of the rare and ordered (CaMn) intermediate member of the Pectolite-Serandite. Brought to light in 2013, they were first thought to be bustamite, then erroneously labeled a new mineral (Marshallsussmanite), it was all corrected in 2018. Exceptional example of the mineral.

Three groups of bright blue cavansite crystals on a white matrix of tiny stilbites. Highly aesthetic miniature. Locality is now defunct.

A wonderful group of straw yellow calcite crystals with a great degree of luster and transparency. Mined in 1986.

Hot pink, luatrous prismatic crystals of rhodochrosite are associated with scattered crystals of the rare mineral shigaite. Ex Desmond Sacco Coll.

Sharp prismatic crystals of purple creedite on a contrasting matrix of botryoidal smithsonite.

A stalactititc (very rare habit here) group of pink crystals on white calcite with an unidentified olive mineral on a manganese matrix. Probably from N’Chwaning 1.
