IODARGYRITE
Broken Hill Proprietary Mine, Broken Hill, Yancowinna County, NSW, Australia

All are miniature size specimens, that is ~ 1 ˝” to 2”size.  They are priced according to richness, and amount of crystallization.  All of the specimens have rich, to very rich, somewhat waxy luster, colorless to pale yellow crystalline and crystallized Iodargyrite in / on dark colored Goethite / Quartz / Spessartine matrix.  Pricing is dependent upon the richness of the Iodargyrite, rather than on the size of the matrix.  Iodargyrite is a silver-bearing halide with the chemical composition:  AgI.  The field of view (FOV) is 8 mm X 6 mm on each of the accompanying photos.  Brief individual descriptions follow:

Item 2554   Rich micro crystalline and micro crystals of Iodargyrite are on Quartz / Goethite matrix, along with scattered micro crystals of light beer bottle brown color Spessartine Garnet crystals.  The Spessartine crystals are usually coated with a micro thin film of Goethite.

Item 2555   Same as 2554.

Item 2556   This example exhibits very rich deposition of Iodargyrite micro crystals, richly scattered in open vuggy areas covering much of the surface of the matrix.

Item 2557   A very rich aggregate of translucent, lamellar white Iodargyrite is on one end of the specimen, accompanied by rich amounts of crystalline and micro crystals of white to very pale yellow Iodargyrite. 

Item 2558   The matrix for this specimen is a solid mass of dark red-brown Goethite, sawed on the base, with a mini-veinlet of Quartz cutting through the Goethite.  Fairly sharp for the mineral, micro crystalline and crystals of Iodargyrite were deposited in several small open vuggy areas in the matrix.

HENMILITE
Fuka Mine, Bitchu-Cho, Okayama Prefecture, Chugoku Region, Honshu Island, Japan   (type locality) 

Dark royal blue color Henmilite xls. are scattered on light colored / white matrix, often semi-botryoidal in habit.  Note that in addition to Calcite, there are several rare white minerals found at the Fuka Mine.  In some cases, more than one of these white minerals can be found associated on the same specimen.  For this reason, it is not appropriate to name the associated white minerals on the specimens listed below, as each specimen would have to be individually analyzed to correctly identify the associates.  There are several areas on most of the specimens where a pale aqua color massive mineral is present, as seen in the accompanying photographs. The name of this associated mineral is unknown.  Chemical composition of Henmilite is:  Ca2Cu[B(OH)4]2(OH)4
