7.8 x 5.9 x 4.4 cm. This Elmwood combo specimen has it all: a fine, glowing purple cube of fluorite (1.5 cm), blooms of snowy white baryte, and a matrix of crystallized sphalerite.
7.4 x 6.3 x 2.5 cm. What you have are these small, very pale lavender fluorites that have formed over a cluster of stibnite crystals, on matrix.
4.4 x 3.4 x 1.9 cm. A pretty miniature of Blanchard fluorite, with the classic teal "Blanchard Blue" color; the crystals measure to 1.7 cm.
12.1 x 8.9 x 3.3 cm. These large, razor-sharp octahedrons have a superb green color with beautiful highlights of purple. This plate is almost all crystal, with just a hint of the quartz matrix. The crystals have the translucency typical for these. The largest crystal measures around 3.4 cm across.
17.9 x 16.8 x 10.9 cm. Topping a large matrix is an 18-cm expanse of fine, sharp crystals of fluorite intergrown with slender, transparent, blade-like crystals of celestine. The fluorites have the typical brown Clay Center color, and measure to 1.5 cm along the edge.
8.2 x 1.8 x 1.4 cm. What you have is crystals of purple fluorite clearly visible inside transparent quartz crystals. This one has 4 crystals inside it, and unlike the great majority of these, is doubly-terminated and undamaged, with a little sidecar crystal that is also in perfect condition.
7.9 x 6.2 x 5.7 cm. Two large, intergrown fluorite crystals showing dramatic zoning, with a golden-yellow core outlined in purple, enclosed in a light teal layer. The larger crystal is 5 cm along the edge.
11.3 x 7.4 x 6.1 cm. Thickly piled up are glowing, golden crystals of fluorite, in knobs up to 2 cm thick in places. This specimen is from relatively recent mining at the Orange River.
17.3 x 13.4 x 5.5 cm. A large plate of unusual colorless fluorite (usually purple from here) from a classic older find at Asturias. These are big crystals, to over 3.5 cm along the edge, with ornate stepped faces. They are decorated with snowy, bladed barytes.
15.2 x 14.5 x 7.4 cm. A superb specimen of amazingly sharp and dramatic octahedrons of fluorite on stark white quartz. This one has just the balance you want of green with purple edge highlights. The crystals here measure to 2 cm.
12.7 x 7.6 x 4.6 cm. A fluorite crystal from Illinois that stretches over 12 cm along the edge. It shows very dramatic zoning - a "cube inside a cube", with the inner one outlined in dark purple - and another purple outline right near the exterior. Those are natural crenellations along the front edge, not damage. The bottom edge has a natural stepped pattern to it.
7.2 x 5.4 x 2.5 cm. From the Okarusu Mine, an amazing specimen of bi-colored fluorite, with glowing purple center and golden-yellow exterior. Crystals measure to 2 cm.
6.1 x 3.8 x 3.4 cm. This combination specimen is unique in that it has crystals on both sides - both on the green fluorite, which characterized this find, and on the other side, which is a layer of crystallized quartz.
8.9 x 6.5 x 3.4 cm. From the Sweet Home Mine, this combination specimen has elegant little blue fluorite decorating a quartz plate, with a sharp and isolated rhodochrosite perched right in the middle. It is a fine crystal of good color, sharp form, and is one inch or 2.4 cm across.
A large knob covered with fine, transparent crystals to 1.5 cm of the characteristic purple and green tones that make this mine famous. The knob is rounded and covered on all sides with crystals - and VERY few dings to be found for a specimen this size! 10.9 x 9.9 x 6.8 cm
