9.2 x 7.9 x 6.3 cm. A sharp specimen with a leaning tower of intergrown crystals perched one atop another and leaning out over the sphalerite matrix to present out to you that 3-cm cuboctahedron floating at the right. The rest of the cluster shows more classic Naica "stair-stepping" and complexly beveled crystals closer to the cubic habit, but with lots of outgrowths. Like many from this pocket, even the back is minutely crystallized or re-healed after an old break, making this complete-all-around and entirely translucent.
11.0 x 9.4 x 5.3 cm. This large specimen features a 4.5 cm (almost 2 inch) gem-clear crystal perched atop a stack of smaller fluorites, all showing the cuboctahedral form but without the usual stair-stepping we see from Naica. These are therefore much cleaner and have sharper edges, with simpler geometry, that make the crystals really stand out a bit more from the matrix. The color grades from clear at the edges to a pale green in towards the core. There is no damage and the crystals are complete-all-around, even around the sides, to the back.
5.9 x 4.8 x 3.7 cm. A beautiful, pristine cluster of large cuboctahedral crystals perched on a galena matrix. They are gemmy and transparent, and complete-all-around except for a small contact in back where you can see some very pretty pyrite inclusions. Classic Naica crystallization.
15.8 x 9.8 x 6.9 cm. A stunning, very rare, multiple crystal, large cabinet specimen of unique and unusual quartz from a one-time, 2005 find in Madagascar. Specimens are very hard to get today. Purple fluorite octahedrons to 4 mm are richly and attractively included in large, dramatic, intergrown, lightly frosted, transparent quartz crystals. The beautiful, sharply terminated spires are complete-all-around and have only a trivial bit of contacting on the back. A striking, visual specimen, enhanced by the long crystal (14.0 cm) and the robust crystal on the right.
13.5 x 11.4 x 6.1 cm. Until these lustrous, translucent, pink fluorites were discovered in Mexico, Peru and the Alps were the only sources for pink fluorite. These translucent octahedrons measure up to 3.1 cm (large for the find), and have vivid, deep pink color against the beautifully contrasting white matrix. A striking, sculptural, curved large cabinet plate. Vivid purple fluorescence.
8.2 x 7.0 x 4.4 cm. Water-clear, very glassy, colorless fluorite cubes cover the sculptural, mounded matrix of mainly bladed baryte on this fine piece from the less well-known Emilio Mine of Spain. Sparkly microcrystals of sphalerite are richly and attractively sprinkled on or included in the fluorite cubes. Heavy for its size, due to the highly percentage of barite in the matrix. Weighs 289 grams.
7.8 x 6.8 x 3.7 cm. Classic, color-zoned, purple fluorite octahedrons to 1.1 cm richly litter the undulating layered matrix of spongy quartz and green fluorite on this fine specimen from the Pine Canyon deposit of New Mexico. The octahedrons are lustrous and very lightly etched/frosted. No damage. Ex. Robert Whitmore Collection # 316 and purchased in 1970 as being from "Catron County". Years ago these were sold as from Catron County to deceive potential claim jumpers. Probably collected by famous field collector, Dick Jones, who worked the Judith Lynn Claim.
8.5 x 4.9 x 3.9 cm. A striking, translucent, cherry-red rhodochrosite crystal cluster from recent Chinese finds. The large crystal in the front with the fluorite crystal at one end and prominent, stepped-growth faces is 5.0 cm. A sparkly field of small pyrite crystals on the back is a nice accent. Many faces are crystallized and some faces are contacted. This remains an impressive, larger example from this locale.
9.2 x 5.9 x 4.8 cm. Very pretty, color-zoned, purple fluorite cubes are richly and aesthetically scattered on the sculptural matrix on this very showy and excellent specimen from a brand new find (2009) at the famous Mina Ojuela. The fluorite cubes, to 1.0 cm, are transparent, highly lustrous and the crystal faces are lightly etched, giving the cubes a waxy lustre. The vivid purple color-zoning makes these highly attractive Mina Ojuela fluorites that compare very favorably with those recovered from any era.
1.8 x 1.5 x 1.3 cm. A rare and fine specimen of sharp, water-clear to translucent, spinel-twinned fluorite crystals with striking, intensely purple color zoning from recent finds at the Shangbao Mine of China. This specimen competes with the best from Naica, Mexico. Very few of these were recovered and they are highly desirable.
8.6 x 6.2 x 5.5 cm. A showy cluster of totally gemmy, bi-colored, light sea-green and colorless, cuboctahedral fluorite crystals is perched atop galena and fluorite matrix. The crowning crystal is 1.7 cm and is beautifully included with a few pyrite crystals. The cuboctahedral crystal corners and edges are lightly frosted. From the older finds at Naica. The two primary capping crystals are pristine. Highly representative of the species and find.
9.4 x 6.5 x 5.1 cm. A showy and excellent fluorite specimen from the recent, very highly touted finds at Riemvasmaak, South Africa. Gemmy and lustrous, unique grass-green fluorite octahedrons to 4.5 cm are beautifully clustered on this specimen of solid fluorite. Some of the crystal faces have a preferential, sparkly, secondary overgrowth of either fluorite or drusy quartz. This is a highly representative example of the species and find. These are contemporary classics. The color is intense, deep green.
6.5 x 4.5 x 3.3 cm. A single gemmy, very sharp crystal to 2.7 cm on edge surmounts a crystallized quartz matrix, here. This is an exquisite specimen and it features unusual isolation of the crystal - most from this find are in aggregate clusters. The irregularity that you seem to see atop is, in fact, simply secondary crystallization adding a few small, gemmy, bright crystals as an accenting fan behind the larger one.
5.4 x 5.3 x 3.3 cm. A fine miniature with exceptionally gemmy crystals, in a cluster, to 2 cm. The two large crystals crowning the piece add elegance and showcase their gemminess well. In person, the slight bits of included brown quartz shard matrix are not as distracting as the photo somehow makes them out to be. The crystals are just so gemmy, you see right through them to the matrix underneath (or in this case, enclosed rather). The top crystals are complete-all-around so that the piece is very 3-dimensional.
6.0 x 3.9 x 3.1 cm. Sharp, glassy octahedra to 3 cm dominate the top of this specimen. They are extremely glassy, lustrous, and translucent in the outer layers, but the interiors are unusual in that they either enclose brown quartz matrix or are themselves colored differently than the outer 6-8 mm or so. This results in unusual dark cores to these octahedra. As a whole, though, the piece is very dramatic and still shows mostly green, in person.
