Minerals Beginning with "C"

JC12363.  Calcite, hemimorphite.   Viola mine, Nicholia district, Lemhi county, Idaho.   5 x 9 cm  152g.  $10.00.    Back in the late 1880's and early 1900's, the Viola mine was one of the largest producers of lead, zinc, and silver in Idaho.  It had a thriving town, now gone.  The low grade ore consisted almost entirely of hemimorphite and some smithsonite.  This is an example of the low grade zinc ore, with micro crystalline hemimorphite crystals partially covered by somewhat blebby calcite crystals.  Good example for a locality piece.   
JC11948.  Calcite.  Elmwood mine, Carthage, Smith county, Tennessee.  9 x 12 cm 946g  $250.00.   A single, terminated crystal with a bit of matrix.  Very minor ding on two places visible in the photos.

JC11853.     Calcite? Speleothem.  Wenshan Mine, Wenshan City, Wenshan, Yunnan, China.  13.5 cm long.  Not sure whether to call this a helictite or speleothem.   Long skinny thing.     Has a neat bulbous end on it.  Rare   $250.00
JC11831.   Manganocalcite, quartz.  Pachapaqui mining district, Bolognesi Province, Áncash, Peru.   2 x 3 cm 8g   $15.00.   Bladed crystals, not lustrous.  Fluorescent sort of reddish pink.  
JC11722.  Calcite.  Santa Eulalia Mining District, Aquiles Serdán Municipality, Chihuahua, Mexico.   8 x 12 cm 664g.    $175.00.  Dominating this piece is a slightly hematite colored dog tooth crystal on the right side, it really sets off the piece, there is just enough of the hematite color to give the crystal a pinkish look.   Smaller crystals are obvious on the rest of the piece.   The dog tooth crystal is modified on the back.

JC11531.  Another view. 
JC11524.  Calcite.  Mid-Continent mine, Treece, Picher field, Cherokee county, Kansas.   2.5 cm thick x 13 x 14 cm    455g.  $150.00.  Colorless mostly gemmy scalenohedral crystals of calcite to 3.0 cm in size forming this matrix cluster.  Very good condition with minimal cleaving present.  Nice old time specimen.

JC11801.  Cassiterite.    Conselheiro Lafaiete?, Minas Gerais, Brazil Or :  Galaleia.   4.8 x 6.5 cm 114g    $250.00  Although the label said Conselheiro Lafaiete, this location has never produced good cassiterite as near as I can tell.  May be mislabeled and be from Galaleia.    A single, somewhat complex crystal.  The base, where it was detached from the matrix, is a sort of fine grained pinkish material, with what appears to be cleavelandite.

JC11849.  Cerussite.  Flux Mine, Flux Gulch, Alum Gulch, Harshaw Mining District, Patagonia Mountains, Santa Cruz County, Arizona.   Box of acicular crystal groups.   $25.00  This is a specimen that didn't make it through the mail so well.    Largest group is 3 cm long.    Dozen or so in there.

JC11476.  Cerussite, malachite.  Mindouli district, Pool department, Republic of the Congo.  6 x 7.8 x 9.3 cm   565g.  $350.00   Here is  a good quality and rarely seen example of Cerussite from the renowned copper district of Mindouli in the Republic of the Congo.   The important aspect of this piece is that it's loaded with dozens of crystals. The crystals meaure up to 2.8 cm with an off-white color and thin prismatic form, and have grown together into what it is commonly referred to a "jackstraw"-shaped group. Most of the crystals are in good shape, however you can see some roughness in places. The reverse side of the piece features a few tiny acicular crystals of green malachite for a nice contrast. This piece came direct in a lot of dioptase specimens from Kimbedi, and stands as one of the finest examples from the locality that I have had to offer.

JC11692.   Cinnabar.  Nikitovka Hg Deposit, Donetsk Oblast, Ukraine.   7 x 12 cm >1000g.  $500.00.   Almost never seen for sale these days, are these solid masses of cinnabar, with the display face composed of a solid layer of cinnabar crystals.   There are several rub spots easily seen in the photo.  A rare specimen. This is a wonderfully rich, classic example of the famous penetration "star" twinned crystals of richly red colored Cinnabar from the Sofiya Mine in Ukraine. Most of the time, these specimens are fairly small, so to have a small cabinet sized piece loaded with crystals like this is a big deal. These beautiful twins are some of the finest examples of the species outside of Tongren, China. This piece features dozens upon dozens of sharp, lustrous, metallic, red penetration twins of Cinnabar . Most of the crystals are in good shape, though some of them have slightly rounded edges when you view them up close. Excellent quality all around, and gorgeous when backlit and viewed up close

JC12364.  Cuprite.  Onganja mine, Helen Farm 235, Seeis, Windhoek Rural, Khomas region, Namibia.   81.9 carats.  About 2.5 cm across.  $2,000.    I acquired a large hunk of massive cuprite some time ago, and when I held it to the light, it appeared to be nearly flawless, so I had it cut into this nice stone.  Quite rare in this size.  Several photos in both transmitted light and normal daylight.

JC11667.  Cyanotrichite, azurite.  Peacock mine, Lemhi county, Idaho.  3.3 x 4.1 x 9.7 cm   92g.  $275.00.  Ex Geary Murdock coll.   Although there has never been a Peacock mine found in Lemhi county, the locality persists as to the location of these.  Mr. Peacock was a mining engineer/geologist with properties he was partially or completely invested in scattered throughout central Idaho.  This may or may not have come from one of his enterprises, or it may have been named Peacock mine just for the colorful azurite etc. found there, wherever there is.   These tend to be rather rare and hard to come by.  The cyanotrichite is in fuzzy light blue crystals scattered thru the center and upper parts of the piece in this view.   Close ups below.
