A specimen of deep-yellow, transparent, lustrous Fluorite crystals hosting a trio of sharply formed, highly translucent, colorless Calcite crystals with minor white Dolomite crystals. This piece has great contrast, especially with the trio of Calcite crystals sitting on top along with the Dolomite scattered...

A large, beautiful transparent to translucent rhombohedral Calcite crystal, 3.5 cm on edge, with intersecting Stilbite crystals on a matrix of snow-white microcrystalline Quartz, with minor Apophyllite. The Calcite crystal has a satin luster  and because of the transparency, the intersecting Stilbite crystals can...

A large plate of Galena and Chalcopyrite on a matrix hosting two prominent, transparent to translucent, light yellow nail-head Calcite crystals. The Calcite crystals are complete and undamaged and contrast very nicely with the metallic luster of the Galena/Chalcopyrite infused matrix. There are a...

A large, beautiful specimen of transparent, blue-green Fluorite with white Calcite crystals (including a bladed cluster) and a small area of sparkling microcrystalline Pyrite to add even more character to the piece. The luster, color, the contrast - it’s all amazing, but the depth...

An exceptionally large specimen hosting numerous translucent, white flattened rhombohedral Calcite crystals on matrix. The Calcite crystals have a soft, waxy luster, are striated, and are quite large. There is crystal growth in the voids, particularly evident on the bottom of the piece (though...

This is a unique, beautiful large piece that features black, lustrous Sphalerite (with Pyrite) hosting a first layer of miniature translucent, white Calcite rhombohedral crystals, then a second layer of larger, layered, pink Manganoan Calcite crystals. The end result is a piece with amazing...

An exceptionally large, hemispherical specimen of rich-pink Manganoan Calcite, exhibiting an inter-grown, fan-shaped, radiating crystal habit on a massive scale, and I mean massive. I haven’t seen a piece this large or well formed before. There are miniature crystals covering the entire front surface...

A large, fascinating specimen of flattened rhombohedral light-pink Calcite crystals in clusters of vertically and horizontally layered crystals in parallel orientation. Often referred to as “poker chip Calcite” or “bladed Calcite.” The mangano Calcite blades populate the entire matrix, creating a stunning aesthetic visual....

This extra-large specimen features numerous clusters of highly translucent, tangerine-colored, flower-like scalenohedral Calcite crystals on matrix. I especially like the contrast of the smaller vertical flower-like clusters with the larger, horizontal singular crystals on the base. The color, the luster and the aesthetics makes...

A beautiful specimen of intergrown, cream-colored Calcite rhombohedrons with a dusting of vibrant green, microcrystalline Dioptase. It’s as if the Calcite has been sprinkled with green glitter - just amazing! This is a spectacular specimen and in excellent condition. Location: Tsumeb Mine, Tsumeb, Otjikoto Region,...

A beautiful piece featuring translucent Mangano Calcite crystals in plumose aggregates. Plumose: “Featherlike aggregate in which many small crystals protrude out of a long, slender one.” (Minerals.net) These pink Calcite crystal formations are an uncommon occurrence, yet these flower-like crystal aggregates are absolutely amazing...

A huge piece that is entirely covered with miniature Calcite scalenohedra. What’s make this piece even more interesting is that these numerous Calcite crystals are clearly arranged into several flower-like clusters, emanating from a center point and radiating outward. Absolutely beautiful! The soft-white color,...

This specimen hosts a cluster of lavender Calcite scalenohedra on a layer of slightly amethystine crystalline Quartz. It’s unusual to see a specimen with such contrasting halves - the large, lavender Calcite crystals across from the crystalline Quartz - like a line was drawn...

This is a beautiful specimen of numerous light pink Mangano Calcite Rhombohedra. The piece appears to be very lightly dusted with a microcrystalline Calcite, giving it a satin luster. Bear with me on this thought: When I’ve displayed this piece next to countless shiny...

This extra large piece hosts 2 generations of Calcite: the first generation is featured on the front which is a layer of bright white, highly lustrous Calcite crystals, and then on the side and back is a second generation of beige colored microcrystalline Calcite...

Really interesting piece: Several small Calcite crystals dusted with microcrystalline Quartz deposited on a plate of Amethyst Quartz crystals, also dusted with microcrystalline Quartz. This makes for incredible luster, great contrast and an unusual yet intriguing, eye-catching piece - I have yet to see...

This piece has great contrast with translucent to transparent lenticular Calcite crystals on a dark matrix. The Calcite crystals, especially the ones in front, are pristine and gemmy,  while the one in back has several Stibnite inclusions (see pics). This is an attractive and...

An elongated Calcite crystal with multiple terminations. Great luster and color and no damage. Location: Yunnan Province, China Size: 9.8 x 3.2 x 1.8 cm

I’m not sure where to begin with this piece - it’s another one of my favorites and I notice something new every time I study it. Besides being huge, the most obvious feature are the Stibnite clusters - their delicateness, metallic luster and flower-like...

What started out as a large, highly translucent yellow Calcite crystal eventually became overgrown on the sides and back with doubly-terminated transparent colorless Apophyllite crystals. The end result is a gemmy, highly vitreous, contrasting and highly aesthetic specimen of Calcite with Apophyllite. I’ve only...
