The mining of Rapid Creek lazulites ended recently, so if you do not have one, it is time to think about getting your hands on one. This is a large, very rich plate covered with not only super-lustrous lazulites to over half a centimeter, but also contrasting golden siderite crystals. 11 x 6.5 x 3.2 cm
Lustrous, saddle-shaped, gray to light brown siderite crystals richly cover this showy, OLD-TIME plate from the famous Traversella Mine, Piedmont, Italy. The specimen comes with an OLD Harvard label. Ex Richard Hauck Collection 7.4 x 5.8 x 2.0 cm
A STRIKING and pristine specimen of large, lustrous and striated, bladed ferberite crystals on brown siderite crystals from the famous Panasqueira Mine of Portugal. This is outstanding material from this well-known locality, which is now closed. Ex Marty Lewadny Collection 7.0 x 5.2 x 3.2 cm
For the last 200 years, these colorless and lustrous, pseudo cubes, of cryolite, from Greenland, a rare sodium, aluminum, fluoride, have been the standard for the species. The locality is not only now long gone, its underwater. THey mined it below sea level, to get cryolite as an important flux agent for the refining of alumninum. Associated with rust colored siderite, some of the cryolite crystals reach .7 cm across. This is a very showy, excellent, affordable, and good-sized example of this now-vanished species 7.4 x 3.6 x 2.1 cm
It is sad to hear that the supply of these gorgeous calcite flowers from Eastern Europe is drying up. Our contact who buys over there told us that these great Romanian calcites are just about finished. These have to be amongst the prettiest calcites around. This one has two intergrown rosettes, stunning with lustre and sparkle, on a carefully trimmed matrix accented with siderite crystals. Perfect size and form, gorgeous aesthetics, just a really beautiful mineral specimen. 6.5 x 5 x 3.75 cm
This is a huge, fine crystal of fluorapatite from the world famous Panasqueira deposit which has arguably produced the finest specimens of this species. This crystal is literally monstrous for the locality! It consists of a deeper-colored green core covered by a layer of secondary apatite. The gray-green crystal is glassy, translucent and is studded with tan rhombs of siderite, to 2.0 cm across. There is minor edge wear but this is one super fluorapatite where , in the context of the remarkable size, a bit of edge wear is certianly forgiveable I think. It is very nearly complete all around, impaled upon a ferberite crystal that partially sticks out the backside 9.2 x 7.4 x 6.9 cm
Three, gem, water-clear at the terminations to faintly green and purple at the centers, apatite crystals to 1.2 cm rest on a matrix of lustrous zoned, hexagonal siderite crystals to 0.9 cm. The 1.7 cm, lustrous and transparent quartz crystal at the top. Smale Collection. 5.2 x 4.5 x 2.3 cm
This locality is best known for its amazing Galena specimens, but there are some excellent Siderite specimens from this locality as well. This "old timer" is at least 100 years old and features several brownish-green rhombohedra of Siderite measuring up to 1.5 cm on Quartz matrix. An attractive historic display specimen from this classic locality. 6.3 x 3.6 x 2.6 cm
An elegant, delicate double-stalactite of small, lustrous, platy olive-green siderite crystals - quite unusual and VERY beautiful! From the collection of Marty Zinn. 9.4 x 2.3 x 1.9 cm
An old Colorado siderite, with sharp blades of olive-brown and minor accenting quartz. 3.7 x 2.2 x 1.9 cm
One of the most aesthetic Canadian siderites with two large, razor-sharp brown rhombohedral siderite crystals growing against one another. 4.0 x 2.7 x 4.3 cm.
Nestled aesthetically in a basalt vug are several, very lustrous, discrete, black, botryoids/spheres, to .7 cm across. Sphaerosiderite is now considered a discredited species name for a rare habit of siderite. But that doesnt change the fact its rare as hell and extremely odd and unusual, even as a varietal. It is old material. Visually pleasing! 6.4 x 5.4 x 3.2 cm
Originally in the collection of noted German mineral enthusiast, Werner Lieber, this siderite specimen features three stalactitic growths. The crystals have a dark, greenish-yellow, highly lustrous, bladed, appearance. I must say that this is one of the nicest siderite specimens I have seen from Germany. BETTER in person! 7.9 x 5.9 x 5.8 cm
This aesthetic specimen features lustrous, bladed, translucent, greenish-yellow crystals of siderite, to 2.5 cm across perched on colorless, lustrous, translucent, crystals of dolomite, to .7 cm across. In addition, there are are brown, metallic, Pyrrhotitecrystals, to .7 cm across and tiny crystals of Cubanite. CLASSIC old Brazil material in very elegant form here! 10.2 x 7.8 x 3.3 cm
this very deep gold mine has produced some of the best siderite specimens in the world. Lustrous, translucent, greenish-yellow, siderite crystals, to 3.0 cm across are perched on colorless, dolomite, to 1.0 cm across. Both species are on matrix. Beautiful , elegant crystals! 6.8 x 5.1 x 4.8 cm
