Copper in and on Calcite (historic, classic)
stock #20.1-519-(304)
Cliff Mine, Pheonix, Keweenaw County
Michigan, United States
6.7 x 5.7 x 2.4 CM (cabinet)
price: $900
Early summer 2021

An important vintage specimen from the famed Wallace Gould Levison collection that he obtained at the mine in 1863. Aside from being old, this is an especially attractive specimen with sharp, clear and mostly transparent Calcite reaching 2 CM. These contain and surround crystalized Copper. The Copper crystals on the surface are well-formed some being dodecahedral and up to 8MM in size. Levison made only one trip from NY City to the Upper Peninsula of Michigan in 1863, he obtained a few nice specimens but never returned. He kept meticulous notes and we will include a copy of the relevant page from his handwritten collection ledger for this specimen. Levison was a dedicated collector, mineralogist, author and inventor active during the 1862-1921 era. His handwritten label is affixed to the back of the specimen. A classic Cliff Mine piece with excellent provenance!

Malachite - Crystals and Botryoidal forms
stock #10.1-500
Katanga, Central Area, Katanga Copper zone
Shaba, Democratic Republic of Congo (Zaire)
8.3 x 6.2 x 4.3 CM (cabinet)
price: $280
Early summer 2021

A classic from Katanga, this is a two sided specimen. One side is composed of sharp radiating fibrous crystals topped by a pair of Malachite balls. The other side is all botryoidal with some distinct chatoyance caused by the balls being composed of fibrous crystals. Excellent condition, color, form and luster. The Shaba Crescent was the source of much outstanding Malachite and these are still very reasonably priced, one of the mineral world's best bargains. In person the color is a bit deeper, darker and the shimmering luster is almost impossible to appreciate in a photo.

Barite (Baryte) on Quartz
stock #6.2-178
Jinkouhe District, Leshan Prefecture
Sichuan Province, China
8.1 x 5.8 x 5.2 CM (cabinet)
price: $440
Early summer 2021

Blue blocky habit Barite crystals on snow white Quartz from older finds at Jinkouhe in Sichuan Province, China. The main crystal is fully transparent, sharp, and has faint phantoms. This is a hefty 2 CM thick and the wide faces are glassy with bright luster while the edge faces are slightly frosted. Nice contrast with the matrix and prettier in person. In very good condition there are only small minor contacts on the main crystal, the quartz is in fine condition and the smaller Barite crystal has a contact area not seen on display as well as a recrystallized edge. This is about as perfect as we can hope for and the piece displays well from most any side. These were common about 15 years ago but are now very uncommon, it seems this is no longer a producing area.

Calcite - curved saddle-form crystals
stock #21.1-226
Herja Mine, Chiuzbala , Baia Mare
Maramures, Romania
7.7 x 4.6 x 3.7 CM (cabinet)
price: $130
Early summer 2021

Sharp edged saddle shaped crystals of Calcite with curved or bent faces in a stacked cluster. The Calcites are a flattened rhomb habit with every face showing the curved plane but most strongly visible on the largest crystals. The Calcites are a very light grey color and in good condition, some minor edge roughness exists and most of the Calcite has a matte luster on the surface that looks textured but several parts also have a brighter smooth surface as well. An odd habit that is a lot like saddle-shaped curved Dolomite but this form is not at all common in Calcite.

SOLD Pyrrhotite -Elongated crystals with Quartz
stock #SOLD AX-7-395 (342)
Santa Eulalia, Aquiles Serdan
Chihuahua, Mexico
8.9 x 6.7 x 3.7 CM (cabinet)
price: $0
Early summer 2021

Unusual and with remarkable form, a cluster of fine Pyrrhotite which all have deep striations and dark golden luster. A fine example from Santa Eulalia, this Mexican Pyrhotite is undamaged and looks great from almost any angle. The largest elongated crystals are intertwined and have a gradual tapering to the termination. Those are about 5.6 CM tall. The color is a dark brassy metallic hue. Not a typical Pyrrhotite but an excellent older and quite impressive Mexican classic. Ex Larry White collection obtained in 1981 from Tony Thurston. Such quality specimens are simply no longer available today.

Celestite (Barian Celestine)
stock #AC-313
Sicily, Italy
9.7 x 7.2 CM (cabinet)
price: $325
Early summer 2021

A beautiful glassy spray of powder blue crystals radiating upward from a massive base. This is a very old specimen from the classic Sulfur locality that has been mined for many centuries. This type of Celestite with the blue color has sometimes been labeled as Barite but often on analysis is found to be Celestite with some Barium. The piece is attractive despite chips and damage to a few crystals. Very uncommon to find material this attractive on the market, the blue color is especially desirable.

Calcite on Hemimorphite
stock #AX-12-178
Santa Eulalia, Aquiles Serdan
Chihuahua, Mexico
11.6 x 2.3 x 2.3 CM (cabinet)
price: $1100
Early summer 2021

A most unusual form and combination. This transparent to translucent Calcite crystal is gemmy and twinned. It is perched on a finger-like shaft, covered with hundred of tiny Hemimorphite blades and also small Calcite crystals. The association and form of this structure is very odd; this was found in the 1970's. The Calcite is complete except for a cleave on the back left side that is not seen on display. Due to that cleave this is not a specimen for the ultra perfectionists, but is incredible for the locality and a very choice display piece presenting an exotic form.

Mimetite with Wulfenite and Calcite
stock #15.1-536
Mina Ojuela, Mapimi
Durango, Mexico
10.3 x 5.8 x 3.4 CM (cabinet)
price: $280
Early summer 2021

Green botryoidal Mimetite is decorated with a few blocky orange-yellow Wulfenites in an open seam. A choice example of this habit and association from Mina Ojuela (Mexico) from the earlier finds in the late 1970's. The matrix is a spongy microcrystaline Mimetite / Wulfenite as well, but outside of the open cavity the color is a less attractive brown and more dull luster. The seam also holds a few Calcite crystals in flattened rhomb form as well. Green Mimetite in this form is somewhat less common than the yellow worldwide.
