Mamuju area, Sulawesi Barat province
Sulawesi Island, Indonesia
4.1 x 2.3 x 2.2 CM (miniature)

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.

Xikuangshan Sb Deposit, Lengshuijiang Co., Loudi Pref.
Hunan Province, China

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
New Year 22

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
New Year 22

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
New Year 22

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
New Year 22

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!

Sphalerite - triplet macle
stock #21-FC-010
Baia Mare
Maramures, Romania
4.3 x 2.4 1.6 CM (miniature)
price: $390
New Year 22

A sharp, textbook perfect triplet or macle twin of Sphalerite on contrasting Dolomite. From the classic Romanian locale of Baia Mare, this is highly lustrous in person. The main twin is a prominent 1.8 CM triangle nicely centered in the center of this cute miniature specimen. Sphalerite is a mineral that is very often twinned, but this habit of triple joining is quite unusual.

Adularia etc. - vintage Austrian
stock #21.1-201
Pragraten am Grobvenediger, Lienz District
Tyrol, Austria
8.6 x 6.3 x 4.2 CM (cabinet)
price: $290
New Year 22

A fine old Austrian alpine specimen with well-formed Adularia crystals that have color zoning from what seems to be Hematite inclusions. In excellent condition this comes with vintage European labels, one from Freiberg. Close exam with good magnification also finds tiny crystals of Sphene, Clinochlore and Rutile but these are not evident in a normal display. Presents well for display the Adularia are up to 1.8 CM and undamaged.
