elm40 - Calcite on Sphalerite - SOLD

Calcite on Sphalerite from Elmwood Mine, Smith County, Carthage, Tennessee, USA [db_pics/pics/elm40a.jpg]

A gemmy, twinned, doubly terminated, ivory colored calcite crystal, measuring 8 cm across is perched on a limestone matrix covered in a druse of calcite and black sphalerite. The underside of the upper termination (pointing back and away from the viewing face) has a very minor cleave but it is otherwise pristine. Dramatic display on a matrix that is unusually sparkly as it is coated by minute calcites and sphalerite druse.

This gemmy, extremely lustrous, twinned, calcite crystal has intense cognac coloring and multi-forked terminations. IT IS RAZOR SHARP and has much mor eintense lustre and color in person. It is also very fat and 3-dimensional. Only very minor cleaving at the bottom-most tip keeps this fine specimen from being pristine and doubly-terminated. VERY much better in person.

Calcite from Elmwood Mine, Carthage, Smith County, Tennessee, USA [db_pics/pics/elm43b.jpg]

Perched aesthetically on a shard of limestone is a GEMMY, twinned, doubly-terminated calcite crystal, measuring 12.6 cm across. The terminations exhibit a fine cognac coloration. There is one tiny ding at the top side of the twinning plane and one termination has a minor (backwards-facing) cleave, but overall the specimen is still lovely and very dramatic for the prrice and size range. The crystal perched in midair , mounted for display by smaller crystals beneath it, and is as elegant as you could ask fgor. It is also MUCH BETTER IN PERSON (more translucent and colorful).

This is a cluster of gemmy, cognac colored calcite crystals, to 14 cm across, on a matrix of gray limestone. The vertical crystal is twinned and doubly-terminated although there is very minor bruising at the upper termination culminating in a backwards-leaning cleave at the tip. There is a slight cleave on the leftmost termination of the left crystal, as well...thee cleaves are really out of sight as you display it, but as a calcite collector I have to note them and downgrade the price...making this a very fie large display piece at a cost that would not have seemed inappropriate even 20 years ago.

This one reminds me of a sailing ship! This very aesthetic cluster of gemmy, cognac-colored calcite crystals are perched on a sliver of limestone matrix. The twinned and doubly-terminated crystal on the left measures 12 cm across while the crystal on the right exhibits 5 multi-forked crystal tips. Only very minor bruising on two crystal tips keeps this specimen from being totally pristine but these are so trivial in context it does not detract. Unusual shape and superb crystal architecture, combined with a very high glassy lustre and the sharp twinning, make this a fine cabinet piece (especially for the price range!)!

Intensely colored, multi-forked crystal tips of gemmy, cognac colored calcite highlight this twinned and doubly-terminated crystal which is pristine save for a bruise at the very tip of the bottom end. It also sits up nicely , and is 3-dimensionally fatter and brighter than the pics convey, so that the deep amber highlights atop show BETTER IN PERSON than you might think.

Two, large, gemmy, cognac colored calcite crystals, to 16 cm in length, oppose each other in a "V" formation. The crystals are doubly terminated. Only very minor bruising is evident at the tips, but in this case the slight damage is pointing down or up and not to the display face so its hard to se eunless you look. However, I have discounted the price anyhow by 75%, from what it would be otherwise if totally pristine to my eye. All in all, thus a LOT of impact for the $$$.

A large plate of gray limestone is encrusted with approximately 25 calcite crystals up to 10 cm across. Most are doubly-terminated and a few are twinned. They are VERY LUSTROUS and many show great relief from the underlaying rock matrix. The largest crystal has gemmy, cognac colored terminations with one end exhibiting multi-forked tips.

Calcite from Elmwood Mine, Carthage, Smith County, Tennessee, USA [db_pics/pics/elm50b.jpg]

This very gemmy crystal is superbly perched on a matrix of gray limestone and is just plain BIG, FAT, and JUICY , with intense color. In person, it is actually quite gemmy with any kind of backlihgting...we did not go overboard at all in the pics and in fact it is MUCH gemmier and more translucent in person than it appears here. The doubly-terminated crystal has an almost beer-colored hue, and it measures 14.0 cm in length x 7 depth x 6 cm width. This specimen is truly majestic in its perch and I value it highly as a special Elmwood.

This is another superb example of Elmwood calcite: Rarely do you see such a large and gemmy doubly-terminated crystal WITH matrix , and in such condition. This hosts a doubly-terminated , twinned, gemmy crystal with a great cognac color, measuring 19 cm across. This crystal is beautifully perched on gray limestone matrix. Only the teeny-tiniest of edge wear or perhaps contacting is detectable on a few small edges near the tip. Just wonderful 3-dimensional display quality! This piece is remarkable for the size and basically undamaged quality of the crystal - if you think about it, and how freestanding it is, its a miracle this thing survived so unscathed.

On a sliver of limestone matrix is a gemmy, lustrous, doubly-terminated and twinned calcite crystal. The transparency and rich glassy lustre is outstanding ! It is complete all around except for one TINY ding on the left edge of the crystal that is rotated aeway from display anyhow. The gemminess on this crystal, for the size, is astonishing; and it is brilliant in a case. My favorite single crystal of the lot here!

This is an aesthetic FLOATER cluster of stacked, modified cubes of galena, up to 2.0 cm across. The battleship gray color and very good luster are supplemented by several, gemmy, golden, calcite crystals, to .7 cm across, on the back side of the specimen. Complete all around!

Manganoan Calcite from Gibraltar Mine, Naica, Chihuahua, Mexico [db_pics/pics/es11b.jpg]

These large, beautiful, frosted pink rhombs of manganoan calcite are from the venerable old deposit at Naica, Mexico. The frosting appears to be a thin coat of silica which adds to the quality of the specimen by giving it a sparkle. The lovely pink translucence, crystals up to 6 cm across, and the sheer perfection of the rhombs, makes this specimen a welcome addition to any collection. Additionally, it fluoresces. OLD MATERIAL, very rare in such good condition for crystals of this size

This is a GORGEOUS and unusually gemmy/lustrous Penn Calcite! It is also big and showy as heck! It features a large, equant, gemmy, lustrous, golden-colored calcite aesthetically arranged on a matrix of smaller calcite crystals. This is an extremely aesthetic matrix specimen because of this form, and the way the main crystal is basically set on a natural pedestal.

Copper included in Calcite with Copper from Quincy Mine, Hancock, Houghton County,Michigan, USA [db_pics/pics/es140b.jpg]

This is a most unique copper-in-calcite specimen. It is a 7 cm rhomb of copper included calcite, well terminated and colored bright pink by the rich inclusions. RHombohedral crystals are rare for the region, and large pseudocubic ones even more so. The crystal is complete on the display faces, though contacted naturally on the upper face. It is hard to tell how much of the backside is contact or cleaved, but there is some roughness in the back regardless (luckily, it doesn't show from front views). In addition, there are five calcite crystal scalenohedra to 1.5 cm, along with native copper, girdling the base . Because they are of more normal habit, and less included than the earlier generation of rhombohedral calcite, they provide a really nice accent to highlight the big crystal and emphasize its weirdness. Lastly, the large, pseudo cubic calcite also appears to be doubly terminated so it is complete on all sides but the back face.
