Cassiterite variety Needle Tin
stock #18.1-104
Minera Monserrat, Challapampa, Poopo Province
Oruro Department, Bolivia
5.6 x 5.5 x 3.4 CM (cabinet)
price: $160
Spring update

A very unusual specimen from Boliva that looks like an old Cornish "needle tin". A three dimensional matrix densely covered with delicate accicular crystals of brown Cassiterite. In fine condition as seen, ex. Hitchings collection. Especially impressive under magnification, this is an uncommon habit and a well crystallized example.
Sphalerite- Dark red crystals on druzy Quartz
stock #6.2-456
Shuikoushan Lead Zinc Mine, Changning, Hengyang Pref.
Hunan, China
7.6 x 7.1 x 3.8 CM (cabinet)
price: $440
Spring update

Dark red gemmy Sphalerite crystals with typical complex twinning are well exposed on contrasting matrix. Excellent luster, the Sphalerites with backlighting glow a bright red, they can seem very dark without it. From vintage 2003 finds at Shuikoushan in excellent condition with no visible damage. The matrix is druzy quartz that has a reddish hue. Very esthetic, these were once found in large quantities but few were this choice, they are no longer available.
HOLD Autunite (Meta Autunite) -very well crystallized
stock #HOLD 16.1-245
Daybreak Mine, Spokane County
Washington, United States
6.3 x 4.4 x 3.2 CM (cabinet)
price: $1200
Spring update

An impressive, well formed and brilliant colored Autunite. From the classic finds of the sixties at the Daybreak mine, this has excellent esthetics and is in exceptional undamaged condition. This specimen has been stabilized so it has not crumbled or lost color, it is very fine condition as seen. The crystals are freestanding from the matrix in clusters and bundles up to 1.4 CM. Color zoning is very evident and distinct. Vivid Fluorescence as is typical of all the best specimens. For such a delicate mineral it is quite remarkable that this has been kept in fine condition.
Quartz var Amethyst with movable bubble
stock #17.1-529
Goboboseb Mts., Brandberg area,
Erongo region, Namibia
7.7 x 2.7 x 2.5 CM (cabinet)
price: $300
Spring update

A sharp, gem clear Goboboseb Amethyst that has a good sized movable bubble and excellent zoning. Unlike most of these so called Brandburgs, this one has no chips or dings, and is far better in person. The Goboboseb area is a very harsh place for digging Quartz, and the small miners camped there do not often find crystals this clean. These Quartz are one of the mineral kingdoms best values.
Beryl Var Emerald, Rare Locale (Norway)
stock #16.1-250
Byrud Emerald Mine, Minnesund
Eidsvoll, Norway
5.6 x 3.8 x 2.5 CM (cabinet)
price: $220
Spring update

Good quality gem clear emeralds on matrix from this seldom seen locale. This mine closed in 1909 after just 10 years, and produced a few good Gem crystals but was not productive enough to compete. It is possible today to visit the dumps and a few Emeralds have been found but usually much smaller than this one. Norwegian Emeralds of quality are very rare in the market. The largest crystal here is 1.4 CM long with very good color and clarity, but not terminated, with chipping and broken areas as seen. Despite the damage it is far better than typical from this locale and this is a choice piece for the area. The color here is due to Vanadium, not Chrome as seen in Colombia. The quality is better than typical Vanadium Beryls at other localities.
Danalite/ Genthelvite/ Helvite- Rosette cluster
stock #17.1-192
Huanggang Mine, Chifeng Prefecture
Inner Mongolia Region, China
3.7 x 3.6 x 2.6 CM (miniature)
price: $2400
Spring update

Simply a killer with perfect form, zoned crystals are arranged in a radiating cluster. These three species are found together as zoned sections of individual crystals at this site. This find at Huanggang (Inner Mongolia) have redefined these species and are widely regarded as the worlds best. The tips of these crystals are translucent and show some internal zoning but the overall display quality of this piece is why this is so exceptional. Helvite and Genthelvite are fairly rare but known from several locales. However good Danalite is ultra rare worldwide these rank as world class crystals.
Rhodochrosite -rare Colorado locale
stock #17.1-868
Idaho Springs, Clear Creek County
Colorado, United States
3 x 2.8 x 1.5 CM (small miniature/ large thumbnail (toenail))
price: $390
Spring update

A single rhomb crystal with fine deep red color from a 1960 find in Idaho Springs. Similar to the better know localities of Sweet Home (Alma) and American tunnel (Silverton this came from an unidentified mine (likely the Moose mine or any of several Central city sites). The collectors were the Hitchings (father and son team) on a family trip from Massachusetts to Colorado. They collected 7 specimens from a boulder in a dump, this being the largest rhomb. They were not sure of the mine name and recorded these only as Idaho Springs.
Quartz- bright red included by Hematite
stock #18.AX-11-403
Orange River, Namakwa
Northern Cape Province, South Africa
5.3 x 1.5 x 1.5 CM (cabinet)
price: $240
Spring update

An extra bright red Quartz from the Orange River. The top half is transparent and the included Hematite makes a slightly zoned look. A tiny tip chatter is just visible and so the price is a lot lower than if it was not there. Good Orange River Quartz has not been found for a few years now and can be very expensive when they turn up. A colorful specimen with eye appeal.
