23.3 x 17.6 x 9.7 cm. These purple fluorites came out of De’an at the same time as the better-known purple and green octahedrons; this was the rarer type of the two to come out during these finds. There are dozens of tightly intergrown crystals here; the individual crystals measure to 2.5 cm.
6.4 x 5.2 x 4.8 cm. A fine Colorado fluorite specimen coming from the Crystal Peak area! Crystal Peak is renowned for amazonite and smoky quartz, but this is really good and it is from the Marty Zinn Collection. Lustrous, translucent, lightly frosted, light purple fluorite cubes to 2.1 cm are nicely set on a blocky, microcline matrix.
9.2 x 7 x 6.6 cm. This giant 7 cm crystal has intense mint-green color, is very gemmy, and has a dodecahedral crystal habit. Associated with it are Tourmalines and Cleavelandite blades.
12.9 x 8.4 x 3.9 cm. These are not stalactites of massive fluorite with little cubes that have grown on them - the cubes actually make up the stalactitic fingers.
9.1 x 6.9 x 2.9 cm. Botryoidal fluorites are rare. This specimen has a gentle curve to it, and fine translucent purple color.
7.0 x 6.2 x 5.3 cm. A rare combination specimen from the Yaogangxian Mine of metallic-bright boulangerite needles to 2.8 cm included in transparent, very glassy, colorless fluorite cubes. The large fluorite cube is 5.1 cm. The boulangerite needles are so dense within the fluorite cubes, that they appear to be gray.
2.6 x 1.5 x 1.3 cm. This piece features a gorgeous, lustrous, sharp, gemmy golden-yellow Fluorite cube measuring 1.0 cm perfectly perched atop a white, translucent Celestine crystal.
2.1 x 2.1 x 1.4 cm. A very attractive Fluorite thumbnail from Yaogangxian featuring a 1.2 cm sharp, gemmy cube with a mystic smoky purple blue color inside and some distorted internal “phantoms”.
3.0 x 2.1 x 2.1 cm. This piece features a sharp, lustrous, GEM, blue and purple “phantom” Fluorite cube measuring 1.4 cm which is perched atop a Muscovite and Quartz matrix.
3.1 x 2.9 x 2.1 cm. This piece features a group of elegant, lustrous, GEM/gemmy, multi-“phantom” Fluorite cubes (the largest measuring 1.2 cm) sitting atop gem quality Quartz matrix.
10.6 x 9.1 x 8.4 cm. A very dramatic specimen that is more 3-dimensional and more covered in fluorite than most such pieces, from finds in 2004-2005. It features robust stibnite crystals as well as thinner ones, in cluster aggregate, all covered by a drapery of translucent fluorite. Ex. Dr. Edward David Collection.
2.6 x 2.4 x 2.4 cm. A fine toenail specimen of fluorite from the exciting Orange River find – showing super-sharp octahedral form and pretty mint-green color.
6.4 x 5.6 x 5.4 cm. The Ojuela Mine is much better known for its adamites and mimetites than for fluorites. This is an older specimen, of sharp, deep purple fluorite cubes (to 1.7 cm) on a matrix of limonite and hemimorphite.
4.4 x 2.2 x 1.8 cm. This is a stack of water-clear crystals of fluorite, with faint purple phantoms inside. The crystals measure to 1.5 cm along the edge.
4.7 x 3.9 x 3.7 cm. This piece features pink rhodochrosite rhombs to 1.5 cm tip-to-tip, on a field of gemmy, light purple fluorites. Some of the rhombs have distorted forms in having grown around cubes of the fluorite.
