Item #27868 Vanadinite, Calcite 5.2x4.2x1.0 cm Largest Crystal Size: 4.5mm $65.00 Hamburg Mine La Paz County Arizona, USA RTD The Hamburg Mine is renowned for its gemmy, ruby-red vanadinite crystals here is a good example. The crystals re sharp hexagonal prisms with wonderful complex terminations. The crystals grew in a tight crack so the larges ones have the imprints of calcite crystals on their sides from the crystals on the other side of the crack. Nice!	Item #27867 Wulfenite 9.0x7.2x4.0 cm Largest Crystal Size: 9mm $95.00 Red Cloud Mine La Paz County Arizona, USA RTD Two, beautiful, orange-red wulfenite crystals are nicely exposed on this piece.

Item #27860 Lepidolite, Elbaite 4.7x3.9x2.8 cm Largest Crystal Size: l-25mm, e-14mm $75.00 Himalaya Mine Mesa Grande, San Diego Co. California, USA RTD This albite and microcline matrix features a rounded, lavender lepidolite crystal well exposed on the side of the white matrix. The lepidolite is as "gemmy" as a mica can get and transmits night light purple light. While primarily a lepidolite specimen, it is worth noting that it has a 14mm, doubly terminated pink elbaite crystal exposed on the side. Nice example of mineralogy from this famous pegmatite.

Item #27856 Fluorapatite 7.3x4.3x4.0 cm Largest Crystal Size: 57mm $250.00 Sapo Mine Goiabeira, Minas Gerais Brazil RTD The Sapo Mine is famous for the peculiar, stepped and elongated crystals of fluorapatite such as these. A one-time find m10, or so, years ago, yielded a number of fine specimens such as this one. Oddly, some of the crystals are hollow and most are terminated by a pinacoid and one pyramidal form. Very light green. Sits JUST like this for display.

This "crossed swords" arrangement shows an amethyst sceptre on one side and a slightly sceptred, quartz crystal o nthe other. The amethyst sceptre is perfect with no damage. If you look close, you can see the small elongated lepidocrocite crystals embedded in the amethyst. Excellent! Displays just like this.	Item #27852 Mimetite, var. Campylite, Baryte 6.0x5.2x4.2 cm Largest Crystal Size: m-5mm, b-20mm $460.00 Dry Gill Mine Caldbeck Fells, Cumbria England RTD When you read through the old mineralogy textbooks or look at older specimens from museums, one mineral that often stands out is the "campylite" from Dry Gill Mine. It is a British classic! Here is an excellent example of the curved, orangey mimetite crystals, that are campylite. The white mineral is bladed baryte, with nice crystals in the cavity. Looks great!	Item #27851 Lazulite 2.1x1.8x1.1 cm Largest Crystal Size: 12mm $45.00 Area A, Rapid Creek Yukon, Canada RTD Just a very lustrous, small plate of deep-blue, lustrous lazulite crystals from the area that produces some of the best!

Item #27849 Quartz, var. Ametrine 6.5x2.7x1.9 cm Largest Crystal Size: as above $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!	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!	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.	Item #27842 Fluorite, Quartz 4.4x2.6x2.0 cm Largest Crystal Size: f-22mm $210.00 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!
Item #27840 Epidote 5.2x4.3x0.7 cm Largest Crystal Size: 45mm $280.00 Hashupa, Shigar Valley Baltistan Pakistan RTD A superb cluster of parallel growth and twinned epidote crystals from this amazingly well crystallized area of the world!

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.	Item #27838 Babingtonite, Prehnite, Quartz 5.2x4.2x2.8 cm Largest Crystal Size: b-17mm, p-15mm, q27mm $225.00 Qiaojia Yunnan China RTD A really nice miniature specimen showing a sharp, composite babingtonite crystal sitting atop a cluster of sharp, colourless quartz crystals and light green hemispheres of prehnite.

The larger crystal is well formed, dark, gemmy green and, like most of these crystals, twinned. This is an excellent example of this mineral that displays well on its acrylic base!
Item #27836 Orthoclase 4.7x3.7x2.2 cm Largest Crystal Size: 39mm $95.00 Muotta Naira Switzerland RTD A single, sharp orthoclase crystal is the dominant crystal in this cluster, along with a number of smaller, crystals with similar habit. Each is a lopsided prism with diagonal stria. No other obvious minerals present. Great looking crystal!!	Item #27834 Aegirine, Microcline, Parisite ps. 6.6x7.3x3.1 cm Largest Crystal Size: 31mm $230.00 Mount Malosa 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.	Item #27833 Mimetite 6.3x3.6x3.5 cm Largest Crystal Size: 11mm $280.00 Pingtouling Mine Liannan, Guandong China RTD An interesting and unusual mimetite! The crystals on this specimen are capped with a lustrous, sharp pinacoidal termination while the prism faces are stepped, sort of skeletal in form. Orangey crystals on solid, iron oxides matrix. Displays very well, just as shown.	Item #27831 Fluorapatite 3.9x2.6x2.4 cm Largest Crystal Size: as above $975.00 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. Excellent example of this mineral with no colouring impurities!
Item #27830 Mimetite 6.9x4.3x3.7 cm Largest Crystal Size: 13mm $310.00 La Mina Ojuela Mapimi, Durango Mexico RTD The front of this thick plate is covered with sparkling, gemmy crystals of mimetite. The mimetite crystals are colourless and show two crystal forms, the hexagonal prism and pinacoid termination. Excellent crystals from an unusual locality!

At the center-right are several topaz crystals, one being much larger than the others. It is 27mm long and 17mm wide with excellent faces. The topaz crystals are a very light, sherry colour. The other topaz crystals are similar but smaller! Nice example from this famous pegmatite region!
