Cornetite - crystallized, with minor Malachite
stock #20.1-142
L Etoile du Congo Mine (Star of the Congo), Lubumbashi
Haut-Katanga Province, Democratic Republic of Congo (Zaire)
10.8 x 6.3 x 5.2 CM (cabinet)
price: $330

A sparkling vivid blue specimen from the famed "sparkle pocket" found decades ago. The piece is well-mineralized on both sides but only one side has the rich lustrous sparkles. The specimen is sawn on one side and this cut is visible from most display angles. Despite that saw mark the specimen is a very rich example of what was perhaps the best find ever for the specie.

Hyalite Opal - Vintage specimen 1895
stock #20.1-296

San Luis Potosi, Mexico
9.6 x 8.4 x 5.4 CM (cabinet)
price: $330

This is both a nice specimen and a fine historic piece as well. The specimen has a slightly faded affixed label from the remarkable collection of Wallace Gould Levison. Details from his ledger (we include a photocopy of the page) says" Bought from William Niven in his new store at 14th street and Broadway (NYC) April 18, 1895". Niven was an important minerologist born in 1850 who was an early partner with the famed dealer George English, later an independent dealer in New York. The specimen is vividly fluorescent and the Hyalite Opal is perfectly transparent looking like bubbles covering a purplish Chalcedony matrix. The only location given in the notes is San Luis Potosi, this is almost certainly from Tepetate. A very choice piece that is both esthetic and a nice piece of History.

SOLD Halite
stock #SOLD 18.1-605
Kerr McGee Mine, Carlsbad Potash District, Eddy County
New Mexico, United States
4.8 x 4.1 x 3.9 CM (miniature)
price: $0

Vivid and gemmy blue Halite crystal nicely perched on a Halite/ Sylvite matrix. From the remarkable finds a few years ago in Carlsbad, New Mexico this Halite has the best rich blue color and fine surface etchings that make this find so important. Choice, undamaged and simply esthetic.

Fluorite- zoned with hollow Barite indentation
stock #15.1-027
Denton Mine, Harris Creek Sub District, Hardin County
Illinois, United States
5.8 x 5 x 3.4 CM (cabinet)
price: $390

Remarkable dark purple Fluorite crystals that have a bright yellow core that is only seen inside the holes left by former Barite rosettes. These Barite holes have a distinctive structure, these are a waxy cone shaped void that shows the detail of the long-gone Barite crystals. These Barite holes are well known from the region but the color zoning on this one is unusual and is especially impressive when backlit. The Fluorite is overall dark, sharp and lustrous with some edge scuffs, so perhaps not for strict perfectionists. The main interest is of course the Barite holes up to 1 CM across that penetrate the inner bright yellow center of the Fluorite.

Hematite with Quartz -unusual locality
stock #16.1-718
Dzhezkazgan Mining District
Karagandy Province, Kazakhstan
4.7 x 3.8 x 2.8 CM (miniature)
price: $340

Choice, mirror bright metallic crystals in a stacked cluster from an unusual locality in Kazakhstan. The main crystal is a perfect hexagon 2.2 CM across. This mine is well known for excellent Copper minerals but this is the first fine Hematite we have seen. The Karagandy region has other localities for nice Hematites but this is both different in habit and better than most we have seen.

Quartz- Tessin habit, Rutile included, doubly terminated
stock #18.1-443
Turbe Alp, Albrunhorn-Turbhorn area, Binn Valley
Wallis, Switzerland
5.6 x 4.2 x 2.1 CM (cabinet)
price: $330

An alpine classic. Transparent, super sharp, undamaged Tessin Quartz crystals in a cross-like cluster. The two main crystals that form the cross are doubly terminated. There are Rutile (sagenite) inclusions in some zones but others are gem clear. The luster is super bright glassy although a few faces have a sparkling dusting of Muscovite crystals. No damage even with good magnification, this is a nice Alpine Quartz and is certainly not typical.

Rhodochrosite - scalenohedral crystals
stock #15.1-046
Uchucchacua Mine, Oyon Province
Lima Department, Peru
5.1 x 3.1 x 2.9 CM (small cabinet/large miniature)
price: $340

A cluster of deep red Rhodochrosite crystals up to 1 CM long contrast with the dark matrix. Rich color and very good luster, this piece from late 1990's vintage mining at Uchucchacua. Scalenohedral Rhodos are much less common than rhombohedral habit and just a few worldwide localities have produced these. There are almost always some tip cleaves on these delicate crystals, this one is no exception but not too many and not distracting. This also keeps this affordable even though it looks like it should be much more expensive. A good intense red color and the crystals are translucent to transparent.

Beryl - tabular Aquamarine on Muscovite
stock #6.2-089
Mt. Xuebaoding, Pingwu Co., Mianyang Pref.
Sichuan Province, China
5.3 x 4.7 x 2.1 CM (small cabinet/ large miniature)
price: $300

A well-defined, transparent, textbook-form tabular Aquamarine crystal perched on Muscovite. The crystal is in far better than typical condition it has some minor contacts and spots where re-crystallization patterns are seen on the wide faces. Only one chip that is not very noticeable which is remarkable, overall quite fine. This habit of Beryl is rare world wide, it was however strangely more common in 2000-2012 at Xuebaoding. The locality has not been very productive and most of the mining has moved to areas with different mineralogy. These are becoming modern classics but can sometimes still be found at a good price.
