NICKELINE (NICCOLITE)
Hans Seidel Shaft (Graf von Hohenthal shaft), Helbra, Mansfeld Basin, Saxony-Anhalt, Germany
This is an old-time crystallized specimen from one of the German localities where crystallized Nickeline has been identified.  The crystals are very sharp, covering almost the entire front of the specimen, part of the back, and at least one edge of the  specimen.  The FOV in the micro photo is 2 mm.  The attached micro crystal photo was done with a Dino-Lite digital microscope. The front and one edge of the specimen are clean and bright, as shown in the accompanying full view photo, and the back of the specimen is darkened (natural surface darkening). 

Specimen size:  2” X 2” across X up to 7/8” thick (tapered thickness)
Order Item:  2857
Price:  $145.

NICKELINE, SKUTTERUDITE, SAFFLORITE
Locality: Nipissing 404, Coleman Township, Cobalt, Ontario, Canada

Description:   Nearly solid mass of metallic pink-gray Nickeline, without matrix.  An open vuggy area runs diagonally across one side of the specimen, lined with metallic, dark gray-black Skutterudite xls., associated with black crystalline Safflorite.  This association is typical of the locality.  All of the other surfaces of the specimen have scattered, micro vuggy areas with Skutterudite and Safflorite.   The Nickeline on this specimen is as fresh and “pink” as possible, without actually breaking the specimen to exposed an unweathered surface.  Nickeline normally loses its metallic pink color upon exposure to the air.  This specimen is so rich and large “as is” that I do not recommend breaking it.

Specimen size:  2 7/8” X 2 1/2” X 2 ¼”   
Specimen weight:  979 grams

IDRIALITE 
Culver-Baer Mine, Sonoma County, California
The Culver-Baer Mine is an abandoned Cinnabar mine that was worked for approximately 100 years, up until the early 1970’s.  It was an important producer of native mercury, used in the recovery of Gold in the placer mines of central California during the “Gold Rush” era of the late 1800’s to early 1900’s.  Idrialite is found at this locality as bright yellow massive coatings and thin veinlets in the silica carbonate rock, almost always associated with crystalline to massive Cinnabar as well as drusy Quartz.  Chemical composition of Idrialite is C22H14, a naturally occurring hydrocarbon mineral.  Idrialite is fluorescent brilliant yellow-golden to yellow-green under both SW and LW UV.  NOTE:  Specimens   # 2756 and 2757 are a pair, split open down an Idrialite-rich seam from the same larger matrix specimen.  If purchased together, there is a -10% discount for the pair, i.e., $63.00 for the pair.

GOLD, CARPATHITE, CINNABAR, QUARTZ 
Los Picachos Mine, Picacho Peak, New Idria District, San Benito Co., California

From a find made in 2015, and verified by XRD analysis, tiny flakes and masses of bright native Gold are present on matrix associated with yellow Carpathite, massive red Cinnabar, and drusy Quartz.  Magnification of 20-30X is required for best appreciation of the micro Gold. Carpathite is a naturally occurring hydrocarbon mineral with the formula: C24H12.   Fluorescence is bright yellowish to blue-white under both SW and LW UV.

TOPAZ, WOODHOUSEITE, QUARTZ
Champion Sillimanite Mine, White Mountains, Mono County, California

Reported from the Champion Sillimanite Mine in MINDAT, and in “Minerals of California” (Pemberton, 1983), crystallized Topaz is extremely rare at this locality, best known as a world class occurrence for crystallized Woodhouseite.  Each specimen has 50 or more colorless micro crystals of Topaz with small, sharp Woodhouseite and dark red micro Rutile crystals associated.  Micro Quartz crystals are also present on items 2742 and 2744.  Specimens 2742 and 2743 are complete floaters, with crystals on both sides of the specimen, without matrix.  Item 2744 is a matrix specimen.  The matrix is a “floater” (i.e., no point of attachment) possibly composed of massive Quartz, coated all over the back of the specimen with a very thin druse of sparkly, micro crystalline Topaz,

GOLD
Diltz Mine, Mother Lode Belt, Mariposa County, California
The crystallized Gold specimens listed below were mined circa 1980-85 when the Diltz Mine was still producing small amounts of specimen Gold.  The mine actually ceased commercial production about 1954, but small claims were worked after that time and some significant finds of crystallized specimen Gold were made.  All of the specimens shown here are very good for micromount preparation.  For additional background information on the Diltz Mine please refer to the “Mineralogical Record”, Vol. 18, No. 1, Jan-Feb 1987, P. 90-92 (Gold II special issue). 

Copies of the “Mineralogical Record” special issues covering Gold specimens / localities are available, as follows.  Click on each link below to review the write-ups on the two special issues of the magazine covering Gold specimens and worldwide Gold localities:
