A plate of lime green prehnite crystals forming sphere that sit on black needles of augite. Obscure Spanish locality that prodices some excellent prehnites.

Bright and golden, striated pyrite crystals sit on a matrix of lustrous jet black sphalerite crystals. The rear also shows some nice (but smaller) pyrites coating the matrix. Very fine old timer from this historical Colorado locality.

A large smoky quartz crystal on a matrix of cookeite, lepidolite and albite. There’s a sharp growth phantom on one side of the crystal and some contact on the rear, but it does not affect the other display sides. An old Eastern classic. Super!

Dirty white crystals of dolomite form a mound next to a water clear quartz crystal that’s included by chlorite. Both of these sit on a matrix of silvery arsenopyrite crystals that are also partly coated by brassy marcasite. You will love the chlorite inclusions under magnification.

A beautiful specimen of lustrous crystals of calcite that have been replaced by light pink rhodochrosite. The Lowe (stating ex JL White coll.), Barstow and Koster labels are included.

Blue green botryoidal rosasite partly coats a matrix of lustrous, dark bluish green willemite crystals.

A bipyramidal crystal of orange scheelite sits on a quartz crystal with muscovite. One minor chip to the right tip of the crystal, but the color and gemminess are unreal! Superb!

A group of highly lustrous, very deep olive green (nearly black) prisms of schorl with a water clear quartz crystal and silvery muscovite crystals. Very aesthetic miniature! You can really see the unique color when light hits it.

A very sculptural specimen of medium purple botryoidal smithsonite. Displays beautifully.

Pastel to medium yellow green scalenohedral prisms of smithsonite coating a three dimensional thin matrix. Pretty!
