Scorodite with Pyrite
stock #AX-5-066
Baishiding Mine, Zhongshan Co, Hezhou Prefecture
Guangxi Province, China
4.6 x 3.6 x 3.1 CM (miniature)
price: $950

Bright gemmy blue and purple Scorodite mixed with Pyrite on a Scorodite matrix. The matrix looks brown in some lighting but the color is from inclusions inside many small Scorodite which are both massive and crystalized. The main crystals are very defined, lustrous and have a very intense color. Overall in fine condition exam with 10-20X magnification finds some tiny rough areas but no serious damage is seen by naked eye. From the find at Henzoh almost 10 years ago, we have not seen any Scorodite from China since, it seems this was a one time find. Scorodite is known from many localities but only a few have good, sizable, bright crystals like these and those are never common.

Frankeite - well-crystallized
stock #21.1-284
San Jose Mine, Oruro
Potosi, Bolivia
4.6 3.8 x 3.7 CM (miniature)
price: $880

A complete floater, crystallized on all sides with slender blade-like crystals of Frankeite radiating in clusters and ball-like aggregates. An incredibly rare mineral, all the best specimens known came from just a few small finds in Bolivia, this is a superb example from what may be the best of those discoveries about 35 years ago. Not long ago Frankeite was often called the rarest Sulfosalt in the world. That may have been true then but today that statement is not true though it is still very super rare. The well-formed balls and clusters are distinctive for this special find at the San Jose Mine. In excellent condition, this displays well from any angle. Ex Dr. Eugene Sensei Collection. As far as we know there have been no more found since about 2005.

Amethyst/Chalcedony 'grape' habit
stock #21.1-410
Mamuju area, Sulawesi Barat province
Sulawesi Island, Indonesia
4.1 x 2.3 x 2.2 CM (miniature)
price: $60

The "grape agate" or ball formed Amethyst from this region is incredible, pretty and affordable. One of the mineral kingdom's best bargains, the color and forms are a great value. This piece is undamaged, has many complete chains of the balls and has the wet sparkling luster that makes these so attractive.

stock #21.1-303
Xikuangshan Sb Deposit, Lengshuijiang Co., Loudi Pref.
Hunan Province, China
6.1 x 4.7 x 1.4 CM (cabinet)
price: $420

A sharp pair of interlocking sprays of Stibnite crystals. Bright metallic luster and patina, there is no matrix, just Stibnite crystals with several types of termination. In excellent condition from a find in 2012 at Xikhuangshan. In person the "gunmetal" bluing effect is pronounced.

stock #21.1-192
Sanda Hills, Mindouli, Mindouli District
Pool Department, Republic of Congo (Brazzaville)
2.4 x 1.4 x .9 CM (thumbnail)
price: $490

A very bright "treelike" Dioptase thumbnail in fine condition. From the recent finds in former Brazzaville (Republic of Congo) which had produced some excellent specimens, some of which, like this one, have unusual yet eye-catching esthetics. In excellent condition, the tiny spray of Dioptase crystals on the display side are all well-terminated and undamaged. The backside has some contacts but still no damage.

HOLD Bournonite - huge crystal, antique, classic German
stock #HOLD 20-FC-047-(9148)
Georg Mine, Willroth, Altenkirchen
Rhineland-Palatinate, Germany
6.4 x 5.7 x 1.8 CM (cabinet)
price: $1550

A major, important antique German Bournonite in a large single crystal. Certainly not pretty but reputed to be the the biggest known single crystal from this famed locale and possibly the largest single crystal from all of Germany. This is also quite sharp for the size at the locale. Over 6 CM across, this is a flat tabular habit as is typical from the Georg Mine. Rather crude in some areas but very sharp in others, it has a few contacts but overall is quite distinct as seen. The vintage Boubée label dates this to late 1800's to early 1900 era, so collected at least over 100 years ago, likely much older. Some faces show an interesting metallic patina and in person there is a fine "gunmetal" luster in spots.

SOLD Brochantite - stout crystal form
stock #SOLD 15.1-562
Milpillas Mine, Cuitaca, Municipio de Santa Cruz
Sonora, Mexico
4.1 x 2.8 x 2.4 CM (miniature)
price: $0

An emerald green mass of Brochantite crystals standing like grass on a miniature sized lawn. These are translucent to transparent crystals with thicker and less fragile form. Most of the Brochantite from here was the very slender and fragile needle habit and often was laying flat on the matrix. The standing "jackstraw" specimens are especially desirable. Already a classic from Milpillas which is one of the world's greatest Copper mines and source of amazing Azurite, the Brochantites from this locale are also world class. A very nice miniature with great luster and color best appreciated in person. In excellent condition, the mine is now closed forever so there will be no more of these.

Pyrite on/replacing Pyrrhotite
stock #21.1-409-(ZSZ)
Contessa Mine, Santa Eulalia District
Chihuahua, Mexico
7.2 x 6.5 x 4.4 CM (cabinet)
price: $1250

Fantastically esthetic and perfectly formed curving Pyrrhotite crystals are covered with bright golden Pyrite. In perfect undamaged condition, ex Arizona Desert Museum. The main Pyrrhotites are slender sparkling gold crystals. With tapering habit some also have twists or curves. The Pyrite on the crystals faithfully follows the crystal striations. A rare and impressive Mexican specimen, the matrix is a mix of sulphides (Sphalerite, Galena) with Calcite, Quartz and Dolomite. The largest, slender crystal is over 6CM long and crowned with a rosette of small Calcite crystals. Way more impressive in person, this is not a typical Mexican Pyrrhotite!
