JC10555.  Ferberite.  Cerro Tazna, Nor Chichas province, Potosi, Bolivia.   5 x 5.5 x 5 cm  351 g.  $95.00    Nice group from this location which hasn't produced more of these for several years.    Black, bladed crystals.   Broken crystal on the lower front.  
JC10555.   Closer view.   The greenish tint on the crystal face on the left is a reflection, as it is dead black in color.  
JC9785.  Ferberite.  Tazna mine, Cerro Tazna, Atocha-Quechisla mining district,Nor Chichas province, Potosi, Bolivia.   5.5 x 8.5 cm   597g.  $250.00.   Nice group of black, sharp crystals with good, bright luster.   The top crystal (edge on in this view) is 3 cm across, and is shown in better view on the bottom photo.   There is a broken crystal on the extreme right side of the piece, visible in the photo.  The main crystals are fairly clean, although there is a tiny ding on the right edge of the main 3 cm crystal, visible on close examination.  Considering how brittle these specimens are this one is in good shape and displays well. 
JC9785.  I rotated the specimen a bit for this photo.  
JC9785.  View of the 3 cm crystal.   The specimen has to be rotated a bit to show the face of this crystal, which I did for this photo.   The broken crystal I mentioned on the main description is visible on the lower right.   When displayed as shown in the topmost (first) photo, it is not obvious.  
JC11625.  Ferro-actinolite, microcline?  Minera I Quarry, Lebrija, Seville, Andalusia, Spain.    6 x 8 cm  96g.  $25.00.    José Luis Otero’s collection (serial number 921).  One of those odd locality pieces.  Black/very dark green ferro-actinolite crystals in a matrix of what appears to be microcline.

JC11527.  Ferro-hornblende. Serpentine dome, New Idria district, San Benito county, California, somewhat near the Benitoite gem mine location.   7 x 10 cm  333g.  $25.00.   A rarely seen specimen of ferro-hornblende from San Benito County, California. A richly, intergrown group of sharp, lustrous, black, prismatic crystals with minor matrix. There is some controversy as to what to call these odd rocks.   Originally they were called barkevikite, since discredited, and called ferropargasite.  I could not find a reference for ferropargasite from San Benito on Mindat, but did find a reference calling these ferro-hornblende.  Sort of take your pick.  I found these two pieces back in the 1970's wandering around the Benitoite gem mine area, looking for outcrops of melanite garnet.

JC11895.   Fluorite.  Xianghualing Mine (Hsianghualing Mine), Xianghualing Sn-polymetallic ore field, Linwu Co., Chenzhou, Hunan, China.  8 x 11 cm   552g.  $75.00.    A large, very pale ice green crystal group.    A few dings here and there.

Tombstone, Cochise county, Arizona.  3.7 x 5.7 x 7.5 cm   113g.  $175.00.   A commercially worked little "mine" where these fluorites are collected.   Crystals are octahedrons for the most part.   Specimen is not back lit, it just tends to be a bit translucent.

JC11031.  Fluorite.  Heights mine, Weardale, County Durham, England.   6.5 x 7 cm  197g.  $ 190.00      Sawn back.  Bluish green crystals that do not change color from tungsten lighting to daylight lighting.  The white material around the crystals is probably calcite.  An older piece, originally purchased from Wards Natural Science, then to the J. P. Osborn and sons collection # 179 then to the Bill Warren collection.  I acquired the piece in August 1983 from Bill.   Crowley collection #: 734.

JC10853.  Fluorite, quartz.  Yongchun county, Fujian, China.   5.5 x 7 cm  204g.  $30.00   Blue crystals on drusy smoky quartz.  Crystals have a dull satin luster.  There has been some discussion that these blue fluorites have been irradiated to get this blue color, so this is a possibility. 
JC10853.  Closer view.  
JC10857.  Fluorite.  Xianghuapu mine, Hunan province, China    7 x 11 cm    534g.  $30.00   Bright luster, glassy crystals with an odd, sort of green/gray color with hints of blue and purple.  
JC10857.   Close up view. 
JC11885.  Frankeite.   Oruro city, Cercado Province, Oruro, Bolivia.  2.5 x 4 cm 72g.  $100.00.  A flattish specimen of frankeite, with poorly developed terminations on the top side.   Quite rare mineral.  
JC11885.   Terminations.  Rather crude looking.  
JC11512.  Galena.  Neudorf, Harzgerode, Harz, Saxony-Anhalt, Germany.   5 x 8 cm  349g  $155.00  Nice grouping of crystals from this long closed mine.   Has an old German label with it that says Nr.27 (collection number on the back of the piece).  "Fundort: Meisenberg Neudorf Harz".  Has a collection or acquisition date of 1962.   Crystals have a slightly melted look.  Although the label is as described as above, a collector in Germany looked this one over and said it is not from Neudorf...he suspects Bulgaria.   So the location is not certain.  Therefore I have discounted the price to $75.
JC11549.  Goethite.  Pikes Peak, El Paso county, Colorado.   3 x 3.2 x 4 cm.  62g.  $35.00.  Nice brilliant spray from the somewhat lesser known Pikes Peak.

JC11840.  Gold.  Mount Gaines Mine (Frenchman Mine) Quartzburg, Hornitos Mining District, West Belt, Mariposa Co., California.  1 cm tall crystalline gold on quartz.  Part of the gold is embedded in the quartz, so it is not glued on.    $325.00   
JC11762.  Grossular.  Jeffrey mine, Val-des-Sources, Les Sources RCM, Estrie, Quebec, Canada.   2 cm thumbnail.   $65.00.
