12.5 x 7.5 x 5 cm. Truly superb specimen of the well-known green Chinese Fluorites. Across the specimen, the Fluorites are lustrous and perfectly gem-clear, as good as I have ever seen on one of these pieces. The largest crystals range up to about 2.5 cm, and they have beveled edges as good as the famous classics from Berbes.
18.5 x 9.3 x 5 cm. Large plate of the now classic red hematite-included Fluorite balls from Mahodari, India. These balls are about 1.5 cm across, and have a dusting of tiny doubly-terminated Calcites. Also, the Fluorites encase a pair of large Calcite rhombs.
12.7 x 11.7 x 7.8 cm. A big fluorite, over 6 cm along the edge, intergrown with a smaller crystal, on a bed of spiky, frosty calcite. The fluorites have the classic golden center, surrounded by transparent light teal blue. This specimen was mined at the Denton Mine in 1981, and came out of the collection of Tom Wiesner.
13.8 x 7.8 x 5.6 cm. This is a stunning specimen that was very hard to photograph, so it is far prettier in person. The fluorites are greener in person than the photos show. The crystal forms are greatly modified, so much so that the surfaces seem rounded - they actually have thousands of tiny stepped microfaces. The fluorites are translucent-to-transparent. But what makes this specimen really special is that the fluorites are in a beautiful balance with translucent, delicate poker-chip calcites. The balance of these crystal and a bit of matrix that shows to provide an accent makes this really a wonderful piece.
25.4 x 17.2 x 8.6 cm. The Blanchard is best-known for teal-blue fluorites, but there are several mines at the locality in fact, and each produces slightly different crystals. One of the adits turned out these deep purple crystals! They measure to 1.5 cm, and are nicely transparent. What makes them particularly pretty are their contrast with the field of orange quartz on which they sit.
Stannite is a rare sulfide of copper, iron and tin. It is collected mainly in not very pretty specimens, as simply a rare and desirable mineral - but on uncommon occasions, you find a specimen that is actually aesthetic as well, like this one. There is a LOT of stannite here, as well as sparing light purple fluorite. But what makes this specimen so good is that the stannite has grown towards the bottom of an elegant, translucent, complete and terminated quartz crystal.
7.7 x 6.5 x 5.3 cm. An OLD-TIME, showy combination specimen of lustrous, tan smithsonite crystals coating lustrous and translucent, lavender fluorite cubes to 1.7 cm on massive galena matrix from the Kentucky portion of the famous and now extinct Illinois-Kentucky Fluorspar District. SELDOM are Kentucky combo pieces of this quality and size available on the market. Very good 3-dimensionality. Essentially pristine, with only trivial periphery bruising. Ex. George Elling Collection.
2.2 x 2.1 x 1.7 cm. An AESTHETIC and CLASSIC Chamonix, France thumbnail of a gemmy, rose-red fluorite octahedron jauntily perched on a glassy, serrated-edge, smoky quartz crystal. A pristine and beautiful specimen.
2.4 x 2.0 x 1.9 cm. A nifty, showy and UNUSUAL combination specimen from the Yaogangxian Mine of China of lustrous, metallic bournonite blades attractively attached to transparent, lustrous, interpenetrating, dark purple fluorite cubes, which are included with bismuthinite needles.
3.6 x 3.1 x 2.2 cm. Botryoidal fluorite is very unusual, of course, and these "fried-egg" specimens from Nasik are particularly prized. This is a fine golden translucent globe, nestled in a bed of quartz. The fluorite measures 2.2 cm.
8.1 x 6.2 x 6.2 cm. This Fluorite is rather an amazing specimen for the variety it contains. The crystals range from cubes to cubes modified by octahedrons, are zoned to uniform, clear to translucent, but always a nice minty green. The edges also vary - straight to stepped bevels. The largest crystal is 4 cm. The luster on all the crystals is very good. Ex. Steve Smale Collection.
11.3 x 7.0 x 6.5 cm. A DRAMATIC and SUPERB purple fluorite CABINET specimen from Berbes, Spain. Very glassy, transparent fluorite cubes to 2.0 cm with excellent edge phantoms cover all sides of the mounded, silicified limestone matrix, with the LARGEST crystals beautifully set at the top of the piece. The 4.7 cm blaze of white, bladed barite is an OUTSTANDING accent to this fine piece.
10.4 x 8.4 x 5.5 cm. This is an OLD-TIMER from Naica - a cluster of transparent fluorite cubes and modified cubes on a base of pink calcite! The fluorites measure up to 2.8 cm across their faces. It is interesting to see that one of the fluorites, for whatever reason, grew in a pseudo-triangular form with beveled corners, right amongst all the cubes! Ex. Gary Hansen collection.
3.0 x 3.3 x 2.9 cm. Here we have a classic association of light sherry colored Topaz with beautiful contrasting green Fluorite. Pakistan has long produced some of the finest Topaz specimens in recent memory, and to find them with any kind of associations is remarkable. The Topaz crystals on this specimen are very sharp, gemmy and glassy with a medium sherry color, but the accenting gemmy green Fluorite cuboctahedron really compliments them well. To top it all off, they are sitting a beautiful snow white bed of Feldspar crystals.
8.8 x 7.7 x 2.6 cm. A beautiful Fluorite specimen from this already classic Chinese locality! It features many intense green, rather lustrous, sharp, water clear cubic Fluorite crystals with deep purple "phantom" contained in the center of the crystals. To top it off the piece is associated with little white contrasting Quartz crystals.
