7.5 x 7.3 x 6 cm. An aesthetic and classic specimen from one the US’s great localities. These beautiful and gemmy penetration-twin Fluorite cubes have good color, fine luster, and the exact mineral combination that you would look for from Elmwood. The main cube is an amazing 4.5 cm across! Contacted in the back, naturally. The front center corner is chipped, but visually it makes almost no difference to the quality of the specimen - your eyes are drawn to the outer corners, where the Fluorites have the clear corners that many Elmwood Fluorites are famous for. Overall, a visually stunning specimen.
5.4 x 4.4 x 3.1 cm. You can see that this fluorite from the Elmwood Mine shows a unique distinction that a few of the crystals from here have - gemmy golden corners that are actually a bit raised above the surrounding faces. When crystals of this type are large and perhaps damaged, these corners are sometimes cut into gemstones, because they are so pure. There is a bit of sphalerite attached here - the zinc ore that was the reason for the Elmwood Mine. This cluster is complete on the display side, with the back being the flat contact face where the specimen was removed from the matrix - it is not a cleave, but is actually re-healed and has formed micro-faces, so the crystal is technically complete all around!
7.0 x 5.9 x 2.9 cm. These Chinese sphalerites have carved out a place as some of the best for the species, for their size, and deep wine-colored gemminess. The large compound crystal here measures over 3 cm across! The sphalerites are on a bed of intermixed micro sphalerites and quartz crystals.
6.2 x 3.1 x 2.7 cm. A sharp galena crystal of 1.5 cm is perched on a matrix of cemented rock shards covered with dark wine-red crystals of sphalerite - a classic combo from here. The corners of the galenas show fascinating modifications, from flat bevels to these weird projections in various modifications of the cubic form. Ex. George Feist Collection.
4.5 x 3.2 x 2.9 cm. Another old Tri-State specimen, this one really striking and impressive: two huge sphalerite crystals, side-by-side - each about 3 cm across! They have textbook form, and sit on just a bit of accenting dolomite. If you are a collector of Tri-State material, you will know that this is an outstanding mini for what it is. Ex. George Feist Collection.
15.9 x 11.9 x 5.9 cm. A BIG, RICH specimen of whopper tetrahedrites from Peru! These crystals, some with a thin coating of brassy chalcopyrite, measure to 2.5 cm along the edge. There is a bit of damage to a few corners, but very modest. In the crook of the specimen is a cluster of quartz crystals that have grown on a patch of sphalerite, which is intergrown with the tetrahedrites.
8.1 x 5.9 x 3.1 cm. This is an incredibly impressive old Tri-State sphalerite with HUGE crystals, probably mined circa 1930s-1960s. The largest here is over 4 cm! A prize for a Tri-State collector! From the important Midwest collection of George Feist.
5.5 x 3.3 x 1.7 cm. A SUPERB and AESTHETIC combination plate from the famous Commodore Mine at Creede, Colorado. Three, sharp, lustrous and brassy chalcopyrite crystals rest clustered on a matrix of VERY GEMMY and LUSTROUS, olive-green sphalerite crystals. A small lot of these was offered at Tucson a few years ago and they quickly disappeared.
9.7 x 5.9 x 5.7 cm. A DRAMATIC old Naica specimen featuring two large, frosty intergrown crystals of calcite (to 5.5 cm tip-to-tip) beautifully accented by the flashy, dark sphalerites on the natural matrix base. The calcites are in pristine condition.
3.4 x 2.4 x 2.3 cm. A gemmy, deep amber crystal of sphalerite, tightly intergrown with a couple of sharp crystals of galena - wonderful old Colorado association specimen from a classic mine in Creede. Ex. John Ydren Collection.
17.2 x 9.4 x 6.9 cm. A large, rich old tri-state combo piece, with a balance of large sphalerite crystals (to 2.5 cm, brassy little chalcopyrites, and dolomites with a slight peach color. Both sides of this thin ridge of matrix are covered with crystals, and you can display it from either side.
7.9 x 6.9 x 6.4 cm. With the mines now closed, Elmwood specimens are getting harder and harder to find. Here you have a monster compound crystal of sphalerite, with individual distinct crystal forms measuring over 4 cm across and ornate, sparkly microfaces - with a cluster of purple fluorites to 1.4 cm. This is a classic Elmwood combo; sphalerite is an ore of zinc, and was the reason for the mining there.
9.5 x 8.2 x 5.9 cm. A big, rich specimen from the now-closed Elmwood, featuring over a dozen limpid purple crystals of fluorite on a mound of crystalline, deep red sphalerite. The fluorites have this superb silky luster you sometimes see in these, that is so desirable. The largest crystal measures 2.8 cm, and has a distinct phantom in it, which is uncommon for Elmwood!
11.1 x 8.6 x 5.4 cm. This is the side of a pocket completely full of sparkly crystals of sphalerite (an old accompanying label says "Zincblende auf Quarz", so it apparently spent time in a German collection). From the 1800s. The crystals are actually wine-red, just very dark. There are accenting quartz crystals here and there.
6.4 x 5.7 x 4.2 cm. A nest of gemmy quartz crystals intergrown with lustrous, dark sphalerites, from Dalnegorsk. This pretty combo specimen is from a pocket encountered in 2002, at the 135 Meter Level of the mine.
