Clintonite in Calcite

Commercial Quarry, Sky Blue Hill, Crestmore Quarries, Crestmore, Riverside County, California, USA

3.7 X 2.8 X 1.6cm

Sharp crystals of Clintonite, a mica-group mineral, silvery green with emerald-highlights, in a light blue calcite matrix. The larger crystal on the display front is 1.0cm at its widest point. One incomplete crystal on the backside, visible to the upper right in the photo on the left; I really consider this part of the matrix. From this piece, it's obvious how Sky Blue Hill earned its name!

Stilbite and Huelandite on Calcite

Pune District, Maharashtra, India

9.5 X 8.0 X 6.2cm

Highly aesthetic specimen featuring two aerial Stilbite crystals, the upper one measuring 4.5cm, with light pink Heulandite crystals scattered across a complex cluster of light gray Calcite crystals. The Stilbite is ivory-white with good luster. No damage other than a few small pocket contacts restricted to the bottom and back o fhe piece. I've had this piece for a while, hence the relatively low asking price, relative to prices the Indian dealers are now asking for their dwindling inventories

Cavansite on Stilbite

Wagholi Quarries, Wagholi, Pune District, Maharashtra, India

10.0 X 9.0 X 5.8cm

Rich electric-blue "balls" to 1.5cm and smaller radiating clusters of Cavansite on white Stilbite. There are approximately five (one is multiple intergrown groupings) completely spheroidal Cavansites beginning with a couple near the base that occupy a small recess, and culminating with the two jewels that crown the top. The back has a small sawn area, which is not visible at all from any proper display angle.

Topaz with Bixbyite

Topaz Mountain, Thomas Range, Juab County, Utah, USA

5.2 X 3.2 X 2.0cm

Another older piece (20-30 years?) featuring glassy, gemmy sherry-colored crystals of Topaz with crisply terminated Bixbyite crystals to 5mm growing toward their terminations. The largest Topaz is 5.2cm long and doubly terminated, and contains approximately 40% of included "sand" Topaz, as does crystal standing upright as currently displayed. The pockets these grew in were very tight, and the crystal facing towards the front on the photo to the left is a heavily "sanded" partial cleave where this crystal "bridged" the void.

Worldwide Mix I


Northern Frontier District, Kenya

4.7 X 3.3 X 2.2cm

From the one-time find that was instantly recognized as one of the world's best, this Epidote crystal features everything that makes this defunct occurrence special: 1) glassy luster (there is some "dusting" by microcrystals on the back), 2) sharp, robust, 3-D crystallization with a complete temination, and 3) strong internal reflections ranging from forest green to small areas of bright yellowish green. The internal reflections, hardly visible in the photos, provide a fish scale-like, iridescent appearance that defines the best from this neo-classic occurrence.

Epidote with Quartz

Green Monster Mountain, Prince of Wales Island, Prince of Wales - Outer Ketchikan Borough, Alaska, USA

4.6 X 3.8 X 2.7cm

So much better in person, this is the best of dozens of very good specimens I've handled from the Green Monster, regarded by some as the world's best Epidote locality. This features a 4.6cm-long, doubly terminated, dark blackish green Epidote crystal with NO DAMAGE, save a tiny chip on the backside. The accenting Quartz crystals contain acicular green inclusions, probably an Amphibole-group mineral (Actinolite?).

Amethyst and Quartz on Galena

Naica, Municipio de Saucillo, Chihuahua, Mexico

9.0 X 7.3 X 6.5cm

Classic, hard-to-find combination featuring slightly radiating clusters of Amethyst crystals to more than 4cm, with later less intensely colored quartz, all on a lustrous Galena matrix. The Amethyst ranges from translucent to transparent pale purple, with distinct smokey quartz overtones, and are typically tapered with slightly sceptered terminations. Original label states Siglo XX Mine from Naica. Usual contacting.

#WW-002          $2,500


Kerrouchene, Khénifra Province, Meknès - Tafilalet Region, Morocco

4.6 X 3.3 X 2.3cm

A complete, well-terminated grouping of nearly parallel Azurite crystals to 3.4cm. Several side crystals are doubly terminated, and the grouping would be doubly terminated save a very small contact at the base where the specimen separated from the surrounding matrix. Otherwise, the piece is damage-free. The Azurites are dark blue with elecric blue highlights, especially on the latest growth faces, and glossy luster. The small, worm-like dissolution features are reminiscent of a few Tsumeb pieces I've handled in the past, but the crystal habit and matrix are distinctly Moroccan.

Topaz with Bixbyite and Hematite ps. after Garnet

Topaz Mountain, Thomas Range, Juab County, Utah, USA

4.3 X 4.3 X 3.8cm

Premier example comprising an undamaged, radiating cluster of "sand" Topaz with scattered, mostly spheroidal psuedomorphs of Hematite after Garnet, with a single lustrous Bixbyite visible on the right side of the photo on the left. Thin overgrowths on the sides of the Topaz crystals are highly lustrous, providing nice bit of flash here and there. An older piece that I first saw in 1998, even then from another "older" collection. The "sand" nickname refers to the sandy appearance caused by alternating growth and etching in the pocket, not inclusions of actual sand.

12 Specimens added June 29, 2016


2nd Sovetskii Mine, Dal'Negorsk, Kavalerovo Mining District, Primorskiy Kray, Far-Eastern Region, Russia

5.1 X 4.2 X 3.1cm

An older specimen with a sharply terminated cluster of "red quartz" from Dal'negorsk, with pinkish white to clear terminations. The crystals on the left side of the photo on the left are tipped, and could be removed to leave a perfectly undamaged specimen, but I believe they add to the overall presence of the piece.

Apophyllite on Stilbite

Pune District, Maharashtra, India

7.2 X 5.0 X 3.0cm

Glassy radiating group of moderately bluish green Apophyllite crystals to 2.5cm, with gemmy light-green tips, on a snow-white Stilbite matrix. From the Lawrence Conklin Collection, it is easy to see why he chose this piece: fantastic aethetics comprising lustrous, damage-free Apophyllite on a "well crystallized," (Mr. Conklin's words) contrasting matrix of the whitest Stilbite one could imagine. Comes with an old label from Willis' Earth Treasures - Minerals with an original price of $370.

Rowley Mine, Theba, Painted Rock District, Painted Rock Mountains, Maricopa County, Arizona, USA

2.9 X 2.8 X 1.4cm

Razor-sharp, orangish yellow "windowpanes" of transparent Wulfenite with tangerine-orange edges and bits of brick-red matrix. The color is uniquely "Rowley," and this is one of the best of hundreds of specimens in this size and price class from the finds made a few years ago. I've featured the larger crystal on the upper right of the photo on the left, partly to address the irregularity along its right side; this is essentially a terminated intergrowth with bits of matrix. There are numerous display angles that minimize this feature; otherwise only one tiny nicked crystal on the backside.
