This is a very fascinating form of Lepidolite - the outside perimeter of the crystal is more-or-less lavender while the inside is translucent to transparent. A beautiful and interesting show piece, especially when back-lit. Location: Itinga, Minas Gerais, Brazil Size: 12 x 7 x 1 cm...

This is a beautiful piece featuring pink intersecting crystals (flattened rhombohedrons) of Manganoan Calcite. The Calcite crystals are highly translucent with a glassy luster and great color. In excellent condition.  Location: Inner Mongolia, China Size: 10.5 x 5.2 x 8 cm

A large, superb specimen featuring numerous, dark-gray, sharp octahedral Magnetite crystals in a contrasting matrix. There are a half-dozen large, well-formed and complete magnetite crystals. This piece and this location sets the standard for Magnetite - in excellent condition. Location: Yinnietharra, Western Australia, Australia Size: 15...

A very aesthetic piece of deep-green botryoidal Malachite with microcrystalline Malachite covering the entire surface, creating a beautiful sparkly luster.

A lustrous, deep-green fan-shaped spray of Malachite acicular crystals on a dark-brown matrix from Tsumeb. A very unique piece and habit. Location: Tsumeb, Namibia Size: 3.2 x 1.8 x 3 cm

A large piece featuring green, fibrous, hemispherical aggregates of Malachite displaying a chatoyant, silky luster (Chatoyancy: an optical reflectance effect, as in “cat’s eye,” arising from the fibrous structure of a material . . . ). A little wordy, I know - but it’s...

A large, deep-green specimen of botryoidal Malachite with an amazing chatoyant, silky luster (Chatoyancy: an optical reflectance effect, as in “cat’s eye,” arising from the fibrous structure of a material . . . ). Great piece in excellent condition. Location: Katanga, DR Congo Size: 11 x...

This piece really caught my eye - the contrast of course is amazing. But to see a cavity filled with a spray of Malachite crystals in perfect condition makes for an unusual and rare piece. Location: Kerrouchen, Morocco Size: 11 x 9.5 x 9.5 cm

A very striking specimen featuring fibrous deep-green Malachite pseudomorphs after bladed Azurite crystals on a white clay matrix. The original Azurite retained its crystal form but was molecularly altered to (or replaced by) Malachite, thus the pseudomorph. The Malachite presents a silky and chatoyant...

A rare and stunning specimen featuring numerous rich-green, sparkling microcrystalline Malachite stalactites rising from (or in their natural state, descending from . . . ) a botryoidal mass of banded Malachite. I was amazed when I saw this piece with all of the stalactites...

A very interesting piece: The matrix front is coated with mostly white to peach-colored miniature Barite blades which have in turn become partially coated with Malachite and lesser Azurite. The contrast really caught my eye, but under magnification it’s even more impressive. There is...

A very aesthetic piece of velvety Malachite with sparse deep-blue Azurite, all on a brown matrix. In excellent condition. Location: Aouli, Midelt, Morocco Size: 8 x 6.5 x 8 cm

A very aesthetic piece of velvety Malachite on deep blue Azurite, all on a brown matrix. In excellent condition.

A very aesthetic, eye-catching specimen of vivid turquoise-blue botryoidal Chrysocolla with dark-green microcrystalline and lighter-green botryoidal Malachite. The banding of the Malachite/Chrysocolla throughout the matrix is really quite stunning. Great piece in excellent condition.

A nice combination piece featuring a shallow vug lined with deep-green crystalline Malachite with accents of sky-blue Chrysocolla throughout the piece, especially on the back. Great color and contrast. In excellent condition. Location: Katanga Copper Crescent, Katanga, DR Congo Size: 6.5 x 2.5 x 7 cm...

A large specimen of fibrous Malachite. The rare “leafy”-like crystals, formed from dense intergrowths of tiny, “fibrous” needles, create a stunning visual with a silky luster and dominate the piece both front and back. In excellent condition. Location: Katanga Province, Zaire Size: 14 x 11.5 x...

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 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...

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 very large and beautiful piece featuring translucent miniature Mangano Calcite crystals in plumose aggregates covering the entire surface. Plumose: “Featherlike aggregate" (Minerals.net). These Calcite crystal formations are an uncommon occurrence - they are unique and extremely aesthetic. In excellent condition. Location: Huanzala Mine, Huánuco Department,...

A large plate featuring a layer of lustrous, pink, intergrown Mangano Calcite rhombohedrons on a dark matrix from Tsumeb. Fantastic color, and great contrast with the matrix. In excellent condition. Location: Tsumeb, Namibia Size: 9 x 3.5 x 5.5 cm

A very aesthetic and large piece featuring translucent, compressed rhombohedral crystals of pink Calcite with a soft, silky luster alongside lustrous, colorless needle Quartz on Matrix. I particularly like the contrast of the Calcite next to the Quartz, especially for both mineral’s color and...

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....

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...

This piece is simply stunning! It’s large with a grey matrix hosting a dense cluster of Mango Quartz. The Mango Quartz crystals are pristine, exceptionally lustrous, transparent, and host a deep-yellow termination (thus the "mango" association). The large focal crystal literally grew on the...

Typical Mesolite sprays with their fragile, needle-like crystals are a challenge to transport to say the least. That’s what I love about this piece - all of the Mesolite crystals are within a vug, thus offering protection to the Mesolite crystals from the environment...

This is a really unique piece - just the sheer size of the main Mesolite sphere is impressive. Also, some might expect Mesolite to be a sphere of delicate needles, but in this case it is more globular with spiky protrusions. The contrast between...
