There are just a couple of small missing bits and otherwise all of the faces are intact. The terminations are nice three-faced trigonal forms and there appears to be A couple of prismatic forms. Very nice crystal from an unusual locality.

  • $120.00
  • Anahi Mine
  • La Gaiba, Sandoval, Santa Cruz
    Bolivia
  • RTD An etched crystal of "ametrine, showing about one third as citrine and the rest as amethyst. I expect that this is probably a shard of a once larger crystal and reflects just a couple of the zones. Very interesting piece. Could cut several nice ametrine gems or just be enjoyed for the mineralogical curiosity that it is!
QuartzDowns Collection, International Minerals
  • Item #27846
  • Quartz
  • 3.9x3.5x0.4 cm
  • Largest Crystal Size: as above
  • $110.00
  • Anahi Mine
  • La Gaiba, Sandoval, Santa Cruz
    Bolivia
  • RTD This specimen is a slice of a special quartz crystal perpendicular to the c-axis. The slice exposes the very interesting and peculiar sectoral zoning present in the crystal. The zoning consists of amethyst in three sectors and light citrinous quartz in the other three sectors. This type of sectoral zoning reflects a very specific chemical zoning where ferrous iron infused quartz crystallized in the amethyst sectors, causing this stunning zoning. In the gem trade it is called "Ametrine". Mineralogists find it interesting, as well! Amazing, really!
Quartz, var. Chalcedony, opalDowns Collection, Arizona Minerals
  • Item #27845
  • Quartz, var. Chalcedony, opal
  • 6.2x3.1x3.9 cm
  • Largest Crystal Size: n/a
  • $65.00
  • Deer Creek
  • Willcox
    Arizona, USA
  • RTD There is an area north of Willcox, called Deer Creek where an unusual type of silica forms. In fractures between basalt fragments, silica in the form of white chalcedony, brownish chalcedony , white opal and quartz crystals form. The brownish chalcedony can have an odd iridescence, when ground and polished the right way. Then is it referred to as "Fire Agate". This piece may have this play of light. The white opal fluoresces a bright green. The back of the specimen is a sort of geode lined with drusy quartz crystals. Very nice example collected by Dr. Downs in 2009.
Fluorite, QuartzDowns Collection, International Minerals

  • Shanbao Mine
  • Henyang, Hunan
    China
  • RTD This piece looks delicate but is actually quite sturdy! It is composed of two fluorite crystals sitting on a thin pedestal of small, milky quartz crystals. The fluorite crystals are squished together and are the sort of crystals that show just cubic faces but arranged as though trying to be an octahedron. Stepped octahedral faces. The fluorites have a light blue green colour, a little darker than shows in the photos. Looks amazing!

  • $150.00
  • Ojuela Mine
  • Mapimi, Durango
    Mexico
  • RTD This piece is totally composed of "pinwheels" of colourless-white hemimorphite crystals. I call them pinwheels because the hemimorphite crystals are divergent to the extent that they seem to form semi-circles of well terminated crystals. This is an exemplary example of this form of this mineral from the prolific Ojuela Mine.

  • Zomba
    Malawi
  • RTD A stunning cluster of pitch-black aegirine crystals associated with creamy-whitish microcline crystals. The aegirine crystals are amazingly sharp prisms with terminations that are steep pyramids. There are also some pseudomorphs on the speicmen that were parisite crystals that have been replaced by a mixture of Ce-rich rare earth minerals. Beautiful specimen! Displays very well! Way better than in the photographs.

  • Shengus Mine
  • Gilgit-Baltistan
    Pakistan
  • RTD This amazing fluorapatite crystal is a single crystal with some stepped growth. It is a short hexagonal prism, terminated by first and second order pyramid forms. The crystal is largely gemmy, with some cloudiness near the middle portions. Near the bottom, there are small amounts of some very fine inclusions of what is probably fine, fibrous byssolite inclusions and some tiny, green, platy crystals of what is probably chlorite.
