Blood red, lustrous, hexagonal crystals of Vanadinite on Barite.
Twinned crystals of the popular collection mineral - Cerussite (also known as lead carbonate or white lead ore), and an important ore of lead. The name is from the Latin cerussa, white lead.
Cerussite Crystal Cluster

Prehnite Crystal Cluster

Calcite Crystal on Matrix
Elmwood Mine, Carthage, Smith County, Tennessee, USA

Nice, light yellow, double terminated Calcite crystal, measuring 6.5x3x2 cm, on matrix from the renowed Elmwood Mine.
Chatoyant Malachite and Azurite
Liufengshan Mine, Guichi District, Chizhou Prefecture, Anhui Province, China
9 x 7 x 4.5 cm
Very aesthetic specimen of chatoyant Malachite with Azurite crystals. Chatoyancy is when light is reflected within the mineral. It is an effect usually caused by a fibrous growth.
Drusy Quartz on Chrysocolla
Manto Tres Gracias Mine, Diego de Almagro, El Salado, Chañaral Province, Atacama Region, Chile
7.5 x 5.5 x 3.5 cm
Astrophyllite Crystals on Matrix
Eveslogchorr Mountain, Khibiny Massif, Khibiny Mountains, Kola Penisula, Russia
8 x 7.5 x 2 cm
Very nice specimen of Astrophyllite, which is a very rare, brown to golden-yellow hydrous potassium iron titanium silicate mineral. It typically forms as  bladed, radiating stellate aggregates. It is this crystal habit that gives Astrophyllite its name, from the Greek words astron meaning "star" and phyllon meaning "leaf"
Calcite Crystal Cluster with Iridescent Marcasite
Brushy Creek Mine, Greeley, Viburnum Trend District, Reynolds County, Missouri, USA
10.5 x 6 x 4 cm
Excellent example of the unique Calcite from the Brushy Creek Mine. This mine is famous for its large gray scalenohedral Calcite crystals, many showing phantom crystals, sprinkled with a combination mix of chalcopyrite/marcasite.

Neon Green Fluorite Crystal Cluster with Quartz & Calcite
Riemvasmaak, Oranje River, South Africa
12 x 8 x 1 cm
Stunning neon green, octahedral Fluorite crystals with adornment of Quartz and Calcite in fine condition. The exact cause of the green color in Riemvasmaak fluorite is still under study. It is probably related to various radioactive or rare-earth species, including lanthanum, ytterbium, cerium, neodymium, samarium, europium, gadolinium and holmium. This is similar to other green fluorites, such as the classic William Wise Mine material from Westmoreland, New Hampshire, U.S.A., where the coloring agent is also rare-earth species.
Celestite Crystal Cluster
Machow Mine, Tarnobrzeg, Podkarpackie, Poland
11 x 9 x 8 cm
Wulfenite Crystals on Calcite
Aurora Mine, Cuchillo Parado, Chihuahua, Mexico
9.8 x 6.5 x 5.7 cm
A rare, old-time specimen from the well-known but small Aurora mine. Striking, lustrous, rust-red, bi-pyramidal Wulfenite crystals to 1.3 cm aesthetically populate a matrix of white Calcite crystals. To me, the most striking feature is the almost metallic luster of the Wulfies, unusual and eye-catching. This is older material, and is seldom available now.

10.6 x 9.9 x 2.8 cm

Gorgeous cubic crystals of pastel violet and olive green Fluorite sprinkled with lustrous crystals of Quartz. This is a rare color from the mine. No damage.
Calcite "Star" on Phantom Quartz
9th September Mine, Madan District, Rhodope Mountains, Bulgaria
9.1 x 8.7 x 4.7 cm
Ex- Rick Hottel Quartz Collection
Disc shaped rhombs of lustrous, ivory colored Calcite (to 4.5 cm) aesthetically perched like a "star" atop a pincushion matrix of translucent, nearly colorless Quartz crystals to 2.5 cm in length. A very unique specimen. In fine condition and even better in person.
Sphalerite var. Cleophane Crystals with Calcite
9th Septemvri Mine, Madan Ore Field, Rhodope Mountains, Smolyan Oblast, Bulgaria
7 x 3.5 x 2.5 cm
Fine specimen of twinned Sphalerite crystals with very well defined faces and edges. Partially coated with very bright Pyrite crystals that have the dominant forms of a pyritohedron. Presentable from both sides.
Opposite Side
Light blue, sparkling spheres of drusy Quartz on Chrysocolla. Rare and very pretty.
Attractive distribution of Amethyst on contrasting matrix.
Beautiful spray of dark golden brown Celestite crystals from the Machow Mine. A few damaged crystals but a minor distraction for this relatively rare specimen.
A fine example of the relatively new Azurite & Malachite finds in Laos. In fine condition.
Excellent specimen of super lustrous Pyrite crystals with well defined, jet black Sphalerite crystals from a recent find in the Huanzala Mine. In fine condition.
Rare on the market specimen of  Hausmannite crystals with Calcite. Hausmannite is usually not a beautiful mineral; however some specimens are truly wonderful. It can have a bright metallic luster and form well-shaped crystals. The crystals are tetragonal dipyramids, an eight faced form that looks psuedo-octahedral.
Aesthetic specimen of a new find of sparkling balls of  purple Chalcedony from Indonesia. Interesting trim of white Chalcedony along the top and left edges. Even better in person.
Back side
Gemmy, green cluster of Fluorite crystals with Calcite from a new find in the Xianghualing Mine. In fine condition.
Another, but far more exceptional Laos specimen of fine electric purple Azurite crystals with Malachite. Very hard to photograph and is more beautiful in person.
Most of the Cleophanes were mined from the 9th September Mine back in the '90s and they have been conspicuously absent from the market for a long time except for specimens held back in some dealer's stock. The Cleophane variety of Sphalerite has always been held in high regard by collectors because of the translucent olive green color and rarity of the crystals.
