Fluorapatite on Quartz and Cookeite
stock #A-7-219-536
Harvard Quarry, Greenwood, Oxford County
Maine, United States
7 x 3.1 x 2.8 CM (cabinet)
price: $1450
Pre Holiday 2017

Attractive and with an unusual esthetic, this is a densely packed matrix of lilac color Apatite. An older specimen from the classic Harvard Quarry in Maine, The druzy Quartz matrix hosts hundreds of small but perfect Apatites most being doubly terminated. In perfect condition and showing well the paragenesis of this locale, this was in the collection of the late Larry White. Two older labels give the locality as Mt Apatite (a more famous locale often incorrectly cited) but those labels are not correct, it is confirmed by Dr. Carl Francis and others as absolutely a classic Harvard piece. Choice and very rare in such fine quality.
Pyromorphite -Classic locale 1880, altering to Galena
stock #17.1-744
Grube Kautenbach, Kautenbach, Hunsruck
Rheinland-Pfalz, Germany
3.9 x 2.9 x 2.6 CM (miniature)
price: $1280
Pre Holiday 2017

A fine, vintage classic specimen of very large Pyromorphite crystals that are partly altered to Galena but are mostly still Pyro. The Kautenbach mine is one of the most distinctive of all European locales and the Galena Pseudomorphs are highly prized. Pyromorphite in sharp hexagons to 2.5 CM across with some zones of Galena coatings and alterations. The oldest label lists a date of 1880, and this is in remarkable condition given that age. Most crystal faces are sharp and complete but some minor edge wear is present. Excellent patina, the Pyro crystals are huge for the location and about as large as were found. Perhaps not a "beautiful" mineral specimen but to many collectors these old Pyros are real treasures. Choice.
Calcite in Fossil Clam
stock #Alec 19-286
Rucks Pit, Fort Drum, Okeechobee
Florida, United States
9.4 x 8.8 x 5.7 (cabinet)
price: $290
Pre Holiday 2017

A far better than average specimen of the remarkable Calcite in Clam shell fossil from the renowned Rucks pit. This was once a prolific small quarry and produced many of the Miocence age fossil Clams. Now closed to collecting and reportedly exhausted, this was a unique deposit. This example is a perfectly complete shell, well defined and showing the Clam exterior replaced by tiny Calcite crystals. The inner void is seen through an opening at the hinge and shows well formed gemmy amber color Calcite prisms to 3.1 CM long lining the inside. These were plentiful in the past, but fine, perfect examples like this were never common and are now especially desirable and rare.
Calcite- Classic form with minor Pyrite
stock #A-13-001
Shullsburg, Lafayette County
Wisconsin, United States
10.8 x 9 x 7.9 CM (cabinet)
price: $390
Pre Holiday 2017

This is a choice Shullsburg Calcite with the classic stepped Scalenenohedral crystals that have enlarged clear prismatic terminations. Far more transparent in person this has glassy luster and faint phantoms of internal Pyrite crystals. In excellent condition the only damage is the base and back lower edge area where this was removed. A choice older specimen, these are modern classics and this is like a textbook example of epitaxial alignment of prism faces.
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
Pre Holiday 2017

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.
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
Pre Holiday 2017

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.
Fluorapatite (Apatite CaF)
stock #17.1-701
La Marina Mine, Pauna
Boyaca, Colombia
1.4 x 1 x .6 (thumbnail)
price: $320
Pre Holiday 2017

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.
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
Pre Holiday 2017

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.
