Anglesite -Unusual form at this locale
stock #16.1-338
Touissit, Toussit District
Oriental Region, Morocco
3.2 x 2.9 x 2.1 CM (miniature)
price: $180


Blocky transparent crystals of white Anglesite with inclusions of Galena seen clearly inside. From the mines at Touissit, this is not the well known form, habit or color most often seen. The form is similar to some specimens from Sardinia or Tsumeb. The condition is good with very minor edge chipping on a few areas not very evident.
Copper with and in Calcite
stock #15.1-892
West Vein, Phoenix Mine, Phoenix, Keweenaw County
Michigan, United States
6.8 x 3.4 x 2 CM (cabinet)
price: $700


Esthetic and not typical at all! Native Copper in leafy tendrils holds and is inside very clear crystals of Calcite. The Calcite is in blocky cube forms with complex growth hills on some faces and colored by the inclusions a bright Copper hue. The Calcites are glassy and the whole composition is very attractive. Some contacts are noted mostly on the backside of the specimen, overall in fine condition. I have not seen another of this style in many years.
Fluorapatite (Apatite CaF)
stock #17.1-701
La Marina Mine, Pauna
Boyaca, Colombia
1.4 x 1 x .6 (thumbnail)
price: $320


A small but incredible gem clear Apatite crystal with the desirable bright pink color. From the La Marina mine in the Emerald belt of Boyaca province that is known for world class Euclase. This has a thin white line inside much like a fadden string which has been noted rarely from this locale. The crystals in the mine often have elongated or widened, distorted prisms, which is seen on this one as well. Very sharp, a very small chip is on one back edge but overall visually clean on the front display side. We visit Colombia several times each year looking for Apatites like this. The production is very sporadic and never large, some years none are seen. This is well above average for color, clarity, form and condition.
Malachite - polished stalactitic section
stock #17.1-700
Katanga, Central Area, Katanga Copper zone
Shaba, Democratic Republic of Congo (Zaire)
6.8 x 5 x .4 CM (cabinet)
price: $350


Sections of stalactitic Malachite can be quite esthetic, especially when the form is more complex and with good color banding. This is an excellent example cut from materials collected in the 1990s. Far better quality and form than average for this sort of slab. The double eye on this piece is especially striking. Polished on both sides but the "back" as seen was near to top knob of the malachite form and so has much more rind. Complete with great form and contrast.
Malachite -stalactitic form, cross section slab
stock #17.1-699
Katanga, Central Area, Katanga Copper zone
Shaba, Democratic Republic of Congo (Zaire)
5.6 x 3.6 x .4 CM (cabinet)
price: $280


Sections of stalactitic Malachite can be quite esthetic, especially when the form is more complex and with good color banding. This is an excellent example cut from materials collected in the 1990s. This style is now becoming rare with the "cauliflower" form. Complete edge rind all around, and polished on both sides.
Anglesite - Gemmy crystals on Galena
stock #16.1-337
Touissit, Toussit District
Oujada-Angad Province, Oriental Region, Morocco
3.7 x 3.3 x 2.4 CM (miniature)
price: $320


The type of Anglesite that is the most desirable from Touissit (or anyplace) are bright lemon yellow, gem clear prisms. This is a nice small specimen of that type, with fine color and contrast on the Galena matrix. There is a small chip on the largest crystal that is reflected in the price but this is not a big distraction. The clarity of the Anglesite is excellent, this is a facet quality crystal at a relatively affordable price.
SOLD Columbite- single crystal from unusual locale
stock #SOLD 17.1-698
Gatumba District
Western Province, Rwanda
3.5 x 2.9 x 1.8 CM (miniature)
price: $0


It is not often we see well crystallized minerals from Rwanda, most are from old collections. This Columbite is quite well formed, it was in the Johannsson collection since the 1970s. Some chipping and contacts as seen but a mostly complete sharp crystal with a nice patina as well.
Rhodochrosite- Sharp Rhombs with Quartz, Pyrite and Calcite
stock #A-22-058
Wudong mine, Liubao, Cangwu Co. Wuzoh
Guangxi, China
7.2 x 6 x 3.4 CM (cabinet)
price: $2600


Intense red color and fine translucent Rhombs from early finds at the Wudong (Wutong) mine. This is one of the few pieces that can match the color and style of some good Sweet Home Mine specimens. Choice and in great condition as seen. The rhombs are just over 2.5 CM (an inch) and very esthetic in their placement. The Pyrite adds a golden sparkle and the overall display is very eyecatching. Later finds produced more pale red and flatter crystals. A less expensive alternative to a similar Colorado specimen but still a fine Rhodo!
