J762 - Dioptase Mindouli District, Brazzaville, Congo small cabinet - 8.5 x 7.5 x 2.5 cm
Slightly cup-shaped formation of solid Diptase. One side shows nothing but bright, lustrous Dioptase crystals with occasional tiny yellow Wulfenites. The other side shows cup-shaped formations of Dioptase, Dioptase crytals, and about 30% coverage of a lighter green mineral with a form of small apple-green translucent globules. This one has both a flashy, showy display side and another side that's interesting under the loupe.
J768 - Dioptase with Wulfenite $ 600 (=~ CAN$ 823) Mindouli District, Brazzaville, Congo small cabinet - 7 x 6 x 4 cm
Bright and lustrous Dioptase crystals on a tan rock matrix. This specimen has interesting crystallization with somewhat wheat-sheaf formations of Dioptase intermixed with small yellow Wulfenite crystals. Saw cut on base.
J894 - Quartz with inclusions $ 250 (=~ CAN$ 343) Madan, Bulgaria miniature - 4 x 3.5 x 2 cm
This is an interesting Quartz specimen I found in a parcel of Galena, Pyrite, Sphalerite and other Bulgarian minerals. It's a complete and undamaged cluster of parallel grown, double-terminated Quartz crystals with a variety of different included and attached minerals including Galena, Chalcopyrite, and Realgar. Pristine and perfect, a gem of a specimen.
J895 - Quartz scepter with Hematite $ 380 (=~ CAN$ 521) Orange River, Karas Region, Namibia miniature - 4.5 x 2 x 2.0 cm
Quartz scepter from a 2017 find, and one of the best I saw. The scepter head has both smokey and amethyst coloration and the stalk is pink due to Hematite inclusions. Complete all around. Withthe exception of two tiny crystals sticking into the side, the specimen is entirely undamaged. The combination of the colors and form make for a great specimen.
J892 - Stilbite on Quartz over Calcite $ 1200 (=~ CAN$ 1647) Jalgaon, Maharashtra State, India cabinet - 10 x 4.5 x 2.5 cm
Laterally compressed translucent white Calcite crystal completely covered by a layer of sugary Quartz crystals, with attached double-terminated pink Stilbite crystals to 3.5cm. Unusual specimen that is reminiscent of Steve Smale's specimen known as 'The Cricket Bat' (see page 117 of the Smale Collection book). One tiny Stilbite crystal is incomplete, otherwise undamaged, with the Stilbite only on one side. Only the second one like it I've seen.
J773 - Hutchinsonite with Pyrite $ 275 (=~ CAN$ 377) Quiruvilca, La Libertad Dept., Peru small cabinet - 5.5 x 2.5 x 1.5 cm
Pyrite and red crystals of Hutchinsonite on matrix. Hutchinsonite is a rare thallium sulfosalt species and these recently found red crystals are some of the best ever found. Crystals reach 5mm long and contrast nicely with the Pyrite.
J810 - Feldspar var. Moonstone $ 800 (=~ CAN$ 1098) Namalulu, Tanzania small cabinet - 8 x 6.5 x 5.5 cm
Blocky, grey/white Felspar crystals from a recent (and seemingly one time) find of crystallized moonstone from Tanzania. This is the single best specimen I've seen with both quality, well formed crystals and good color. The main crystal is 4.1cm wide and displays a satiny blue color across the end surfaces. This 'Schiller effect' is seen when you turn the crystal under lighting. Good color can be seen on a number of the other smaller crystals too. Moonstone crystals are rare!
J920 - Copper $ 750 (=~ CAN$ 1029) Ajo, Arizona, USA large cabinet - 32 x 13.5 x 1.2 cm
Large Ajo Copper with a row of tall crystals to 13cm!!! The crystals formed in a seam and the specimen has a uniform thickness for it's entire length. This was in an old collection I bought and based on the other minerals in the collection, I estimate it's from the 1970s or 1980s. Reminds me of one of those old two-person saw blades used to cut down giant trees.
J774 - Clinoatacamite $ 290 (=~ CAN$ 398) Lily Mine, Ica Department, Peru miniature - 4 x 3.5 x 2.5 cm
Selenite and Chrysocolla lined vug with large, robust crystals of dark green Clinoatacamite to 9mm. The Clinoatacamite is especially good on this one. These are regarded as the world's best Clinoatacamite specimens. The Lily Mine is now closed.
J775 - Clinoatacamite $ 200 (=~ CAN$ 274) Lily Mine, Ica Department, Peru miniature - 3.8 x 3.5 x 3 cm
Selenite and Chrysocolla lined vug with large, robust crystals of dark green Clinoatacamite. These are regarded as the world's best Clinoatacamite specimens. The Lily Mine is now closed.
J971 - Hutchinsonite with Pyrite $ 1250 (=~ CAN$ 1715) Quiruvilca, La Libertad Dept., Peru cabinet - 12 x 8 x 2.5 cm
Pyrite and red crystals of Hutchinsonite on matrix. Hutchinsonite is a rare thallium sulfosalt species and these recently found red crystals are some of the best ever found. Crystals reach 8mm long and contrast nicely with the Pyrite. Undamaged with an even distribution of both species across the front face. About as nice a Hutchinsonite specimen as you could expect and the best one I've ever had.
J974 - Hutchinsonite with Pyrite $ 500 (=~ CAN$ 686) Quiruvilca, La Libertad Dept., Peru small cabinet - 8.5 x 6 x 2.5 cm
Pyrite and red crystals of Hutchinsonite on matrix. Hutchinsonite is a rare thallium sulfosalt species and these recently found red crystals are some of the best ever found. Crystals reach 6mm long and contrast nicely with the Pyrite. Undamaged with an even distribution of both species across the front face. Top quality.
K133 - Clinoatacamite $ 225 (=~ CAN$ 309) Lily Mine, Ica Department, Peru miniature - 5 x 3.5 x 2 cm
High quality specimen of Clinoatacamite with an isolated crystal group 1.1cm wide atop sparkling drusy Quartz crystals. Good crystals of this rare species. The Lily Mine is now closed.
K136 - Clinoatacamite $ 425 (=~ CAN$ 583) Lily Mine, Ica Department, Peru small cabinet - 7 x 6 x 3.5 cm
High quality specimen of Clinoatacamite with an isolated crystals atop sparkling drusy Quartz crystals. Good crystals of this rare species. The Lily Mine is now closed.
D152 - Prehnite $ 1800 (=~ CAN$ 2470) Merelani Hills, Arusha, Tanzania cabinet - 12.5 x 7.5 x 6 cm
Large, catepillar-like formation of Prehnite crystals. A very interesting specimen for it's unique form, distinct crystals, and coloration (way better than photos - the camera didn't pick up the blue green color well). New finds at Merelani have produced Prehnites with a color I've not seen before, sort of a mixture of both green and blue. This specimen features both typical lemon yellow and the new blue/green colored crystals. While most Prehnites from other parts of the world occur as botryoidal masses or spheres, Merelani produces well formed, distinct crystals, and this specimen is loaded wtih them. It has double-terminated clusters to 5cm and individual crystals to 3cm. There is one small smooth area where it contacted a Calcite crystal, otherwise it's a floater covered by crystals on all sides, with little if any damage. One of the best, if not the best, Merelani Prehnite I've had. Minor Pyrite and Graphite in association.
