A fine piece from an American classic locality, the Tristate Joplin area. This was once a great producer of good minerals, it is now long gone and high quality pieces have become very scarce. This esthetic and unusually colorful piece has a 6 CM twinned butterscotch Calcite contrasting with ruby-red Sphalerites. In great condition, 1940s vintage specimen this is piece would have been far better than average back when these were plentiful. Today this quality is almost never seen.
Calcite on Flourite
Minerva #1 Mine, Cave-in-Rock, Hardin County
6.8 x 5 x 4.3 CM (cabinet)
Delicate and esthetic slender crystals of calcite are perched in a jackstraw jumble on purple Fluorite. Despite a few cleaved tips this still displays super well. Classic old time specimen, this sort of material is now quite uncommon.
HOLD Calcite enclosing Chalcopyrite
stock #HOLD AC-385
Faraday Mine, Farady Township, Bancroft District, Hastings County
5.5 x 5.4 CM (cabinet)
Ex Joe Stachura. From the one time find about 30 years ago, this is a killer example of this esthetic discovery. A glass clear Calcite (optical grade) encloses a garden like array of bright Chalcopyrite in many forms. The impact and condition are great, some minor rough spots exist as seen on the photos but this is still far better than most. Rare to find on the market, these are treasured pieces unlike anything else!
Campomorto Quarry, Montalto di Castro
Viterbo Province, Latium,
8.8 x 6.8 CM (cabinet)
Exquisite spherical calcite on basalt from a classic old location. No damage, this displays well and has a beautiful soft luster.
From a small find in the 1970's this calcite is very esthetic and colorful. The matrix is a sparkling white to light yellow druse of Calcite covered with hills of deep red to black drusy crystals. A single later generation clear crystal is perched on one side and all is well-arranged and eye-catching. A very pretty display quality specimen that is uncommon, unusual, undamaged and still affordably priced.
Classic calcite on sulfide and dolomite matrix from the great discoveries at Shullsburg. Esthetic and well presented, the calcites reach 3.2 CM. The backside isalso displayable. The front display face appears damage free (magnification finds micro nicks)there is contacting on the reverse but all in all it looks pristine. These are well respected as great and distinctive specimens, this is a good affordable example.
Fengjiashan Mine (Daye Mine), Daye County, Huangshi Pref.
6.8 x 5.5 CM (cabinet)
A wonderfully displayed gemmy calcite (4.2 CM across)sits on a small shard of matrix that is dusted with smaller gemmy Calcites as well. Great form and condition, the calcite has some glass clear faces and interior and others with a very light frosting. This looks great from any angle, from one side looking like an old English Calcite and from others like a modern Dalnegorsk piece. This is from the Daye Mine in Hubei, China which has produced a lot of great Calcites, but this one is distinctly different than others we have seen.
Calcite (frosted) on Quartz
Rossie Lead Mine, St. Lawrence Co.
4.8 x 4 CM (miniature)
From the classic old locality of Rossie that was active from 1830 to 1860. A nicely frosted main crystal with a few smaller on the sides sits on a Quartz matrix. No damage, good clarity and some internal rainbows . This seems to be an untwinned crystal that was less common at Rossie. Calcites from here were used in many crystallographic illustrations and studies in the classic literature. These are rarely available now.
