Fluorite, Quartz and Siderite
stock #20.1-864
Krupka, Teplice District
Usti nad Labem Region (Bohemia), Czech Republic
4.1 x 3.1 x 2.7 CM (miniature)
price: $140
new year 2021

A very dark purple cube of Fluorite nestled in a cluster of red and yellow Quartz crystals which are colored by Hematite inclusions. A small bit of Siderite is also noted. An old specimen from this important and very historic Czech locality that has produced many different Fluorites over the centuries. These are not seen for sale very often outside of the Central European region, but they are quite prized there.

Quartz - faden with bend and twist
stock #16.1-303
Waziristan Ophiolite, North Waziristan
FATA Federally Administered Tribal Areas, Pakistan
8.9 x 3.6 x 3.1 CM (cabinet)
price: $750
new year 2021

A really extraordinary Quartz. Faden Quartz is well-known as being found in distorted, flattened and elongated crystals, always with the internal "string" or line inside. This piece has all that in elegant gem clear crystals in a series of chains and clusters, but in addition it also has a remarkable bend with a slight twist. We have handled many great Fadens from the Waziristan finds but this is the only piece that has this remarkable form. This is nearly all Quartz, with just a sliver of matrix and is in fine condition, one edge contact is seen with magnification, this display incredibly well. A super addition for any Quartz suite or collection, this is especially impressive in person.

Galena - classic locale
stock #13.1-168
Saxony, Germany
3.9 x 3.6 x 2.7 CM (miniature)
price: $550
new year 2021

A very fine miniature of a pair of intergrown modified octahedrons. This habit is classic and distinctive for this ancient German Silver mining locality. In excellent condition with a dark metallic patina, this is clearly a very old specimen though without documentation. Worldwide the vast majority of Galenas are crystallized as simple cubes or modified cubes. Octahedrons are far less common but were more frequently seen in central and eastern Europe, especially from a few of the ancient German mines. An excellent textbook clean example.

Wulfenite on Gypsum and Calcite
stock #15.1-710
Ahumada Mine, Los Lamentos
Chihuahua, Mexico
4.8 x 3.4 x 2.6 CM (miniature)
price: $150
new year 2021

A cute miniature of Orange Wulfenites on a snowy white matrix of both Calcite and Gypsum. The Wulfenites have the bright wet look luster that is well-known from this locality. In excellent condition, this piece is from the most productive period, over 40 years ago.

Fluorite - classic British yellow
stock #19.1-405
Hilton Mine, Scordale, Hilton Escarpment District, Murton, Eden
Cumberland, Cumbria, England
5.7 x 4 x 3.2 CM (cabinet)
price: $280
new year 2021

A nice cluster of gemmy and sharp Fluorite cubes from the famed Hilton Mine, collected in 1974 by Les Hitchings. The crystals are quite clear, transparent and undamaged. The largest cubes are over 1.2 CM across and have a vivid fluorescence as is typical of much Fluorite from this region. The Hilton Mine was of great importance to mineral collectors as it was the source for lemon-yellow Fluorites which were quite distinct and different from most other British locales. A very nice yet more affordable specimen of this classic material.

Tanzanite (Gem Blue Zoisite)
stock #19.1-849
Merelani Hills, Lelatama Mountains, Simanjiro District
Manyara Region, Tanzania
1.8 x .9 x .7 CM (thumbnail)
price: $330
new year 2021

A brilliant blue thumbnail gem crystal of Tanzanite. In excellent condition with glassy luster and fine transparency, this is an affordable specimen of this often very expensive mineral. Good Tanzanite like this has a striking color shift across the "C" axis when rotated it shows a purple color shift. Some color zoning is seen in the crystal but it is overall a choice royal blue. 5.17 Carats

SOLD Lepidolite with Muscovite core
stock #SOLD 16.1-751
Aracuai, Jequitinhonha Valley
Minas Gerais, Brazil
9 x 5.7 x .4 CM (cabinet)
price: $0
new year 2021

An oddity, this is an attractive well-formed Mica crystal with fine zoning and a sharp transparent window in the core. The outer zone of Lepidolite is a rose purple and shows thin color bands when backlit. This piece is from a small lot that arrived in 2017 and I have not seen anything like this since.

Hiddenite (Spodumene) - vintage USA Classic
stock #15.1-699
Stony Point, Alexander County
North Carolina, United States
2 x 1 x .6 CM (thumbnail)
price: $750
new year 2021

A fine single crystal of Hiddenite from the area of the original discovery in Alexander County, North Carolina. While green Spodumenes have been found in other regions, true "Hiddenite" only comes from this locale and these do not fade their colors like green Spodumene from elsewhere. It had been surmised that a Chromium content adds the color as it does to the Emeralds that are found in the same area. However testing for both Chrome and Vanadium has not confirmed this. This specimen is from the Dr. Warren Johansson collection which he obtained in 1934. The crystal is fully natural (no irradiation), doubly terminated, gemmy, undamaged with good color and complex etching. These were never common and are now quite rare.
