Fluorapatite on Microcline
stock #7-13-414
Imilchil
Anti-Atlas Mts., Morocco
9 x 7 x7 CM (cabinet)
price: $250


A pinkish matrix of crystalized Microcline is host to many yellow- green crystals of Fluorapatite many of which are doubly terminated. These crystals are a little greener than the classic Mexican Mercado examples and with a very different matrix. This is not a common locality. There are some broken crystals evident.
Franckeite (var Potosiite)
stock #7-R-13-193
San Jose Mine, Oruro
Oruro Department, Bolivia
7.5x4.6 CM (small cabinet/ large miniature)
price: $1800


Potosiite is the rare Tin poor variety of the rare mineral Franckeite, and was a separate species until it was discredited in 1997. It is still a very rare Sulfide with crystals larger than micros considered huge. From a small find of the worlds largest and best crystals at the San Jose mine, this is a top example with individual crystals to 1.3 cm. For this rare and ugly mineral this is a true killer and even esthetic! This was rated as one of the best 7 pieces found.
Native Sulpher w. Gypsum
stock #8.2- 110 X
Girgenti
Sicily, Italy
4.7x4.2 CM (miniature)
price: $110


From another classic locale this older miniature has well formed orthohombic crystals in an esthetic and oriented arrangement. These mines are long closed and have produced some of the best Sulpher ever found. This is a good example of the crystal form that made this location famous and is affordable compared to most.
Bournonite
stock #6.2-893
Yaogangxian Tungsten Mine, Yizhang County
Hunan, China
3.5x3 CM (small miniature)
price: $160


Very bright, metalic and with fine luster, this bournonite miniature shows excellent form with a pleasing contast to the matrix. Much better than usual condition for this delicate, brittle mineral, however there is some chipping and contacting like all of these have. The main crystal shows a fantastic cogswheel form. Since well crystalized Bournonite is very uncommon, the better Chinese examples are already becoming classics. For now, this is a bargain!
Cerussite (old classic locality)
stock #AC-187
Bad Ems
Nassau, Germany
2.9x1.6 CM (thumbnail)
price: $180


A pre-1930's piece from the classic location of Bad Ems, best known for fine pyromorphites. This is a sharp, glassy cerussite with only minor edge chipping. It is rare to see minerals of this quality available from these old European locations.
Barite on Calcite
stock #8.1-X117
Stoneham, Weld County
Colorado, United States
4.2x4.1 CM (miniature)
price: $80


Nice light blue Barite, standing on a contrasting yellow crystaline calcite. The main crystal is 2.7 CM and sharp with no damage. There are some very small crystals scattered on the matrix that do show damage but they are not distracting. An attractive piece from this classic American locality, at an attractive price.
Pyromorphite
stock #4.2-458.1
Daoping Lead-Zinc Mine, Yangshao
Guangxi, China
2.4x2.5 CM (thumbnail)
price: $40


A very well formed and sharp cluster of hoppered crystals with good color. These are from the early 2001 finds and are simply great Pyromorphites at a super price.
HOLD Spinel (historic locale)
stock #HOLD AC-034
Amity, Orange County
New York, United States
3.6 x 2.8 CM (small miniature/ large thumbnail (toenail))
price: $145


A fairly sharp and substantial single crystal of Spinel from this lost historic location. Old Schortman label included. The crystal appears black but some edges under magnification show a dark translucent green that may be an alteration. Tiny bits of mica and calcite still adhere but this really not a matrix piece, but simply a single octahedron from a lost, classic locality. Some chipping and contacts but still in reasonable condition given the age of this piece.
