HEMATITE
Monte Calvario, Biancavilla, Etna Volcanic Complex, Catania Province, Sicily, Italy
These exceptionally brilliant black, submetallic luster, tabular Hematite crystal groups are available from a find made in 1982.  All specimens have extra sharp, striated and/or stepped growth faces with mirror-like surfaces, without matrix.  Specimens from this occurrence were pictured in the “Mineralogical Record” magazine, Vol. 14, No. 1, P. 55 (1983), labeled only as having been found in Sicily. Another mention of this find appeared in Vol. 14 on P. 176, with the corrected locality information given.  Items 2002 through 2005 below are individual specimens, not mounted, and will be shipped in white cotton filled specimen boxes.  Items 2006 through 2011 are “thumbnail” size specimens, mounted in plastic “Perky Boxes”.   Recent information published on MINDAT indicates:  “Today collecting is forbidden and the quarry is closed.”  Specimen sizes are given: length X width X thickness.

GALENA
Mandan Orefield, near Mandan, Southern Rhodope Mountains, Bulgaria
The Mandan Orefield is situated near the Bulgaria-Greece border, and the sulfide ores of the district have been mined since the 5th-6th centuries, B.C. ! A very good article covering the mines and minerals of the Mandan Orefield appears in the "Mineralogical Record" magazine, Vol. 22, No. 6 (Nov-Dec 1991), P. 439-445 -- data on the various crystal habits of Galena is given on P. 443-444. The two specimens listed below are both aesthetically appealing crystal groups of sharp, metallic luster, lead-gray crystals on matrix. The largest Galena crystal on item A. is a cube with octahedral faces, measuring 1/2" X 1/2". Micro crystals of Quartz are associated on item A. The largest Galena crystal on item B. is a 1/2" X 3/8" cube, and the associated minerals are micro crystals of Quartz, Sphalerite, and Chlorite. Order items MI-003, A. or B.

RHODONITE ! ! !
San Martín Mine, Chiurucu (Chiuruco), Huallanca, Bolognesi Province, Ancash Department, Peru

Yes, this is crystallized Rhodonite, not Rhodochrosite! This occurrence was reported in the "Mineralogical Record" magazine, special issue on Peruvian localities, July-Aug 1997, page 56 (28:4:56). The occurrence is also mentioned briefly in the "Mineral News", June 1998, page 5, paragraph 1.  As shown in the accompanying photographs, the Rhodonite from this locality has formed attractive groups composed of individual, often prismatic, terminated crystals without matrix.  The specimens offered here were mined circa 1997-1998.  Associates noted include minor amounts of micro crystalline Sphalerite, as well as Pyrite and Galena on specimens 2313, 2794, and 2795.

CAVANSITE with STILBITE, HEULANDITE
Wagholi Quarry, near Poona, Maharashtra State, India

The Wagholi Quarry has been worked for many years as a quarry for basalt, which is used for construction purposes.  It is without a doubt the finest locality known, worldwide, for crystallized Cavansite.  For an account of the discovery of the crystallized Cavansite found at this remarkable locality, see the “Mineralogical Record” magazine, Vol. 22, No. 6, Nov-Dec 1991, P. 415-420.   Each specimen has an individual, bright turquoise blue color spheroidal crystal cluster, composed of many intergrown Cavansite crystals resembling a three-dimensional asterisk (*).  The Cavansite crystal clusters were deposited upon small shards of basalt breccia, associated with one or more individual terminated white Stilbite crystals.  Drusy micro crystals of Heulandite are also present on both specimens, coating the dark colored basalt matrix.

ARSENOPYRITE
Panasqueira Mine, Panasqueira, Covilhã, Castelo Branco District, Portugal

The Panasqueira Mine has produced some of the most aesthetic Arsenopyrite crystal specimens found at any of the European localities.  The two specimens listed below are from the collection of Lorraine Sofia of Daly City, CA.  They were both collected circa the mid-1990’s.  Specimen # 2316 has some contact damage around the base and back of the specimen, and no rock matrix.  Micro Pyrite crystals and dark brown-black Sphalerite cleavages are present on the back of the specimen.  Specimen # 2317 has exceptionally well crystallized, bright metallic silver color, slightly curved Arsenopyrite crystals associated with several small, light tan colored Muscovite rosettes, and no rock matrix.

DRAVITE  TOURMALINE
Blue Sky Prospect, Santa Cruz, Sonora, Mexico
This locality has been known and worked for many years for beautifully crystallized, satin luster, fan-like crystal groups of black Tourmaline.  The Blue Sky Prospect is a pegmatite in the Santa Cruz District, and this district has been worked since at least the 1950’s for Tourmaline, Scheelite, Powellite, Apatite, and other minerals.  Originally thought to be Schorl, primarily because of the color, the Tourmaline from this locality has more recently been identified as Dravite.  The crystals are actually a dark brown-black in color, and have a wonderful satin luster.  The basic habit of crystallization on these specimens is fan-like intergrowths composed of multiple crystals on Quartz matrix.  Item E. only has an very attractive, upright, fan-like intergrowth composed of many satin luster Dravite Tourmaline crystals perched on top of a healed section of a large smoky Quartz crystal.  These specimens were collected circa 15 years ago.  All are exceptionally attractive!
