ALTAITE
Hilltop Mine, Organ District, Organ Mountains, Dońa Ana County, New Mexico, USA

This historic locality for Altaite, PbTe, has been known since before 1930, according to the references listed in “Minerals of New Mexico”, S. Northrop, P. 101-102, 1959.  A recent find, made circa 2012, yielded the specimens listed here.  Altaite is present as bright metallic silvery grey veinlets and masses running through the matrix.  The Altaite was difficult to photograph, to sufficiently illustrate the bright metallic silvery grey color, and all specimens are definitely better than shown in the photos. Most specimens illustrated here also have Altaite showing on one or more additional sides or back of the specimen not visible in the photographs.  Very minor associates of Galena and Sphalerite are present on some of the specimens.  Submicroscopic amounts of metallic blue Rickardite were noted on some specimens, but only visible with 30-40X+ magnification.  Pricing is according to the richness of the Altaite, not relative to the overall size of the specimen.

DIAMOND (native element, C)
Mirny Mine (Mir Mine; Mir Pipe; Myr Pipe), Mirny, Saha Republic (Sakha Republic; Yakutia), Eastern-Siberian Region, Russia

All of the crystals in this group are of the habit known as macle twins, or spinel twins.  The basic outline of a macle twin is a triangular shape, with the twinning on (111).  All of the specimens are clear-colorless, and none have matrix or point of attachment.  The scale on each photo gives the size reference.   The average size of the single macles (triangular crystals) is 2.5 mm.  Item MI-2059, a double macle, is not quite as sharp as the other specimens, but interesting nonetheless.  It is 3.5 X 2.0 mm in cross section.  Three of the Diamond crystals are fluorescent.  Items MI-2055 and MI-2058 exhibit a strong blue-white fluorescence under both SW and LW UV.  Item MI-2056 is fluorescent transparent, light yellow under both SW and LW UV.  Quantity discount:  -10% on a purchase of 3 or more.  OK to combine specimens from different localities to get the quantity discount.

DIAMOND (native element, C)
Akwatia Mine, Birim Diamond Field, Eastern Region, Ghana

All of the crystals in this group are colorless, untwinned octahedrons.  The scale on each photo gives the size reference.  The average size is ~ 1.5 mm to 2 mm.  None are fluorescent.  Quantity discount:  -10% on a purchase of 3 or more.  OK to combine specimens from different localities to get the quantity discount.

DIAMOND (native element, C)
Quebrada Grande River, Guaniamo, Bolivar, Venezuela

All of the crystals in this group are colorless, untwinned octahedrons.  The scale on each photo gives the size reference.  The average size is ~ 1.5 mm to 2 mm.  The first 4 crystals, MI-2071 through MI-2074, have very minor inclusions.   Item MI-2077 is very weakly fluorescent transparent yellow under both SW and LW UV.  Because of the very small size of the crystal, it is difficult to observe the fluorescence under the microscope.  Quantity discount:

 -10% on a purchase of 3 or more.  OK to combine specimens from different localities to get the quantity discount.

GOLD – Rosia Montana (Verespatak), Romania

Rosia Montana is probably the most famous of the European Gold localities.  Several fine color photographs of Gold specimens from this locality are featured in the “Mineralogical Record” magazine, Vol. 13, No. 6 (Gold I issue), Nov-Dec 1982, P. 360, 36l, 364, 369, 372, and 373.  The text on P. 374 briefly describes the Rosia Montana locality and Gold specimen habits found there.  The Gold is always very bright, and was found as crystals, leaves, wires, and dendritic aggregates.  The specimens pictured at the left are from the F. Marshall collection, and each consists of a very bright intergrowth of leaf / wire Gold.  The dimensions of the specimens are recorded on the photographs.  The three larger specimens are associated with a small amount of crystalline / micro xls. of white Calcite.  No rock matrix.

NOTE:  The following special Gold issues of the “Mineralogical Record” are also available for purchase:

Gold I                          Vol. 13, No. 6,             Nov-Dec 1982             Price:  $55.
Gold II                        Vol. 18, No. 2,             Jan-Feb 1987              Price:  $18.
