Here we have one of the great "classics" from the United States. Some of the most colorful and stunning Fluorite specimens ever found in the United States are those from Hardin County, Illinois. This district produced literally tons upon tons of some of the finest quality, multi-colored Fluorite the world has ever seen. This specimen is a nice sharp, rich gemmy purple and blue color, phantom crystal. Like all specimens from this area, the color always looks better in sunlight, and this crystal is exceptionally rich and vibrant when viewed outdoors. This area is completely closed down and there will never be any more Fluorite mined there. 5.5 x 5.5 x 5.3cm
This plate of fine purple fluorite crystals on sphalerite measures over a FOOT across! The piece is covered with silky purple fluorites to about 2 cm, with fine transparency. You just do not see many pieces of this magnitude from the Elmwood, especially now that the mine is closed and the supply of specimens has dried up from the market. There are a few little dings but I counted only 4 in the main central part of the specimen; and the remaining edge damage is peripheral. The specimen is so large that they are not really noticeable amidst the 100 or so crystals. (mostly, it is just trivial damage around the periphery). So, for a piece of its size, it is in great shape. A real showpiece! Extra shipping due to large size and weight. 31.5 x 26 x 4.5 cm
A superb thumbnail of the famous "water-clear" fluorite from Dalnegorsk, represented here in a 1.5-cm cube perched perfectly on matrix. The crystal has pretty, natural bevels on the edges and corners. 3.9 x 3.9 x 1.8cm
The pic does a pretty good job of showing how amazingly unique this crystal is, even with the good quantities of fluorites coming from this mine. It is stepped like some sort of Central American temple, all the way to the termination, and is complete all the way around! Plus, it has really nice deep purple color and gemminess. I do not recall having seen another like this, even with all the material from there! 4.1 x 3.9 x 3.9cm
This material gobbled up as soon as it appeared, and the mining of it was very short-lived. What you have are large, glowing, translucent green crystals of fluorite on an earlier generation of grayish-purple fluorite crystals that you can see through the interiors of the green ones. This specimen has a whopper 6.5-cm crystal amongst the others (it does have a small, shallow cleave, but there is very little damage at all on this specimen overall). 11.3 x 9.7 x 6.3cm
I apologize for the vagueness of this description - a friend picked this set up from a dealer who was selling this amazingly pretty fluorite without being given the locality. At any rate, what you have here is an emerald-cut stone of very unusual beauty and gemminess (for fluorite) measuring 1.5 cm, along with a euhedral specimen of the raw fluorite from which is was cut. In person, the stone is actually slightly more to the green side of blue - it is really much prettier than the pic shows, and you would never believe it is a fluorite - looks like some exotic apatite or tourmaline. Fluorite is soft, so if you plan to set the stone in a piece of jewelry rather than keeping it in a gem collection, a pendant is suggested rather than a ring. 3.4 x 2.7 x 2.4cm, 1.8 x 1.6 x 0.9cm
A gorgeous plate of fluorite crystals from the Okarusu Mine, exceptional in that they have gemmy green interiors with purple corners! You get some variety in thr fluorites from this mine, but this has to be one of the more unusual and pretty ones! 10 x 9.5 x 2.2cm
The matrix here is completely covered with gemmy golden barite crystals, and on one side, calcite crystals have grown during a later phase in the pocket. This is a classic combination from Asturias. 5.2 x 3.8 x 2.6cm
A very aesthetic Madoc fluorite, with the crystals arranged beautifully at the top of a rising matrix of bladed barite. This is a classic old mine, I think now closed to specimen production. The crystals have a pretty light green color, and show fine transparency. They measure to 2.4-cm across. 7.5 x 7 x 6 cm
A pretty English thumber of calcite crystals on purple fluorites. 2.7 x 2.6 x 2.1cm
Another pretty thumbnail specimen from England, this one a cluster of cubes of golden fluorite. Ding on the back corner of the large crystal, but it IS on the back. 2.7 x 2.4 x 2.1cm
This teal-blue crystal is of a very unusual modified form for the Yaogangxian, with two sides showing tiny stepped growth with purple coloration, and the other two clear, so they have a very pretty contrast. The large crystal is quite transparent inside. 8.5 x 7.2 x 5.1cm
A large plate of wonderfully transparent fluorite crystals, to 2 cm on edge. Most of the crystals have interesting stepped corner modifications (that is NOT dings you see!). 15 x 10 x 4.5 cm
An AESTHETIC and SUPERB, old-time Heights Mine plate of two, water-clear, interpenetrating, green fluorite crystal clusters to 1.4 cm jauntily flanking a euhedral, 2.5 cm galena crystal. The gossan matrix is festooned with a multitude of smaller fluorite crystals. The right fluorite cluster has a nearly invisible corner bruise. OUTSTANDING purple fluorescence. 9.7 x 7.6 x 4.0 cm
A phenomenal Aussie specimen...This just has to be one of the best Tasmanian fluorite specimens around, considering that none of the mines have ever been really noted for fine fluorite and here is a CABINET piece with an in-your-face huge crystal atop a mound of smaller crystals. The single largest face is more than 5 cm across! It has a stunning seafoam-green-blue color to it, excellent lustre, and very good transparency right down to the matrix underneath. The crystal is complete on the display face and sides, slightly contacted on the rear edges and the back only. The matrix piece features stepped growth, light pastel green, lustrous and gemmy, fluorite crystals. 12.2 x 9 x 8.5 cm
