9.8 x 8.0 x 6.1 cm. The yellow fluorite cubes from the Hilton Mine have always been among the favorite specimens from the Midlands of England, and are very rare compared to the green and purple crystals which come out of many other mines while these typically come from just the old Hilton mine. This particular matrix specimen features several penetration-twinned, gemmy, yellow, fluorite cubes to 1.75 cm across, that are perched on smaller cubes of fluorite. The specimen fluoresces a rich lavender color. Ex. Dr. Edward David Collection.
2.5 x 2.4 x 1.7 cm. A totally gemmy 1.7 cm crystal of the quality found long ago, certainly in the early 1800s as this is characteristic of a specimen from the era. Ex. Laura and Stevia Thompson and Eric Asselborn Collections.
5.0 x 4.9 x 3.5 cm. A superb specimen from Cal Graeber's summer mining project. They were about to give it the last season here, when they hit what is now called "The Jewel Box Pocket," with some of the finest green penetration twins ever found in England. These are huge crystals for the locality, to 3 cm on edge, and gemmy. The color saturation is intense. These fluoresce a deep vivid purple even in sunlight...you don't even need a UV light to get the effect. A window, a door even, lets in enough natural UV to make them bicolor green and purple as you twist the specimen in the light rays.
11.5 x 9.5 x 3.4 cm. This large specimen features a 2.4 x 1.5 x 1.2 cm gemmy crystal, twinned into a slightly smaller cubic fluorite; as well as another 2.4-cm twin in the middle of the specimen starkly standing out from the simple cubes around it. From Cal Graeber's "The Jewel Box Pocket," this piece has some of the finest green penetration twins ever found in England. The color saturation is intense. These fluoresce a deep vivid purple even in sunlight...you don't even need a UV light to get the effect. A window, a door even, lets in enough natural UV to make them bicolor green and purple as you twist the specimen in the light rays.
7.8 x 6.7 x 4.8 cm. I am really fond of this old fluorite from the venerated Heights Mine even though the crystals do not appear to be twinned in the "classic" manner you expect. The crystal is also rather large. The combination of drusy, white quartz surrounding the green, gemmy, well formed, 3.5 cm fluorite crystals is outstanding. They fluoresce somewhat, even in just daylight...in fact there is a hint of purplish-blue when viewing the fluorite through the side faces just in normal lighting. There is also a second generation of fluorite which has grown on the drusy quartz. Ex. Lindsay Greenbank Collection.
36 x 29 x 6.4 cm. This beautiful specimen literally glows with vivid deep green color. The crystals are naturally lustrous and glassy, and very gemmy. The average crystals are gemmy as little ice cubes, and in size to 1.7 cm. Some are penetration-twinned in classic style. There must be hundreds of them here. Weighs 20 pounds.
10.7 x 8.7 x 3.8 cm. This is one of the nicer matrix fluorite specimens from the Sweet Home mine. Many of these gemmy, lustrous, crystals are bi-colored, with deep purple cores and white edges. The largest of these measures 1.25 cm across. For color contrast, there is even a cleaved rhodochrosite rhomb and colorless quartz crystals to 1.0 cm across. Quite rich and unusual for the locality. From the Jelly Pocket.
8.4 x 4.3 x 3.8 cm. Since the Rainbow Pocket was found in one of the earliest strikes at the reopened Sweet Home in 1992, there have been gemmier and brighter crystals. Nevertheless, this pocket stands as a historic find and a unique style. From this pocket, many floaters were recovered, coated with minute fluorite crystals. According to Steve, who got to pick early on, this was the most elegant and aesthetic piece for his tastes from the find. It is complete, undamaged, and a floater. While not having surface lustre of a high order, the crystals here (as typical for the pocket) have a fine cherry-red color, just spectacular when backlit. This is, again, one of the earliest fine specimens from the reopening of the Sweet Home in the early 90s, and to my eye remains a uniquely recognizable specimen even amongst all that came out later of different styles. Ex. Dr. Steve Smale Collection.
12.9 x 8.8 x 4.4 cm. A fine cabinet plate richly covered with very glassy, transparent, golden-yellow fluorite cubes to 1.0 cm from recent finds at the Moscona Mine, Spain.
7.4 x 5.4 x 3.8 cm. A beautiful, ice-like, water-clear, 3.0 cm, light green fluorite cube very aesthetically set on matrix and surrounded by smaller fluorites on this fine specimen from recent finds at the Xianghualing Mine of Hunan Province. This cube has fabulous beveled edges and corners and the crystal has a superb water-clear, "aquarium effect", where you straight through to the matrix beneath the crystal.
12.5 x 12.2 x 5.4 cm. Sharp, vivid purple fluorite cubes with outstanding gemminess and lustre form a superb, 3-dimensional cabinet plate from the famous, but less well-known Deardorff Mine of the Illinois Fluorspar District. The two largest cubes are 3.8 and 3.6 cm wide. The fluorites are beautifully accented by scattered quartz crystal clusters and there are even a few ruby-jack sphalerite crystals. This is classic, old-time material from this mine dating from the 1930s to 1950s, as the mine closed in the early 1960s.
9.5 x 8.1 x 5.5 cm. A very fine and aesthetic fluorite on sphalerite specimen from the Elmwood Mine. A large, 5.7 x 5.3 cm cube has gemmy, colorless to white interior and classic, outer purple zones. The cube faces are lustrous and have the typical, stepped-growth faces. The corners are starting to get gemmy, another hallmark of Elmwood fluorites. The fluorite is very nearly pristine. Ex. Consie Prince Collection.
5.8 x 4.5 x 3.9 cm. Clusters of gem, yellow fluorite cubes to 6 mm are scattered on the vuggy, 3-dimensional, amethyst matrix on this fine and uncommon combination specimen from Thunder Bay, Ontario. There is also pink, bladed baryte on this piece. Thunder Bay is world-renowned for amethyst and to see starkly contrasting, yellow gem fluorite cubes on purple amethyst is a very pleasant surprise.
11.1 x 7.5 x 6.0 cm. Lustrous, color-zoned, purple fluorite cubes to 5 mm are aesthetically scattered on the knobby and nubby, 3-dimensional matrix of white albite crystals on this fine, cabinet specimen from the summer, 2008 find in the Monster Pocket at the Dreamtime Mine of Teller County, Colorado.
4.5 x 3.4 x 2.4 cm. Beautiful, water-clear, cuboctahedral fluorite crystals with intense purple, color zoning on a shard of matrix form a superb specimen from recent finds at the Shangbao Pyrite Mine of China. The primary faces of the lustrous crystals look just like glass plates; you look straight through to the matrix and see the beautiful color zoning. The flanking crystal faces have a very interesting stepped-growth and really add character to these amazing fluorites.
