Vuagnatite and McGuinnessite (type locality)
stock #ALEC-10-938
Red Mountain, Mendocino County
California, United States
9.8 x 6.2 x 3.1 CM (cabinet)
price: $330
May 2015

A sizable matrix densely covered with white to colorless Vuagnatite crystals and contrasting McGuinnessite in green spheres. Vuagnatite is a rare mineral discovered in 1975, and McGuinnessite is very rare, discovered in 1981. This is from the type locale for Mcguinnessite, and is a very good specimen of both species. This could easily yield several fine thumbnails if trimmed out. Very good color and bright sparkling luster make this an unusually attractive rarity.
Barite w. Fluorite & Pyrite
stock #ALEC-10-846
Niobec Mine, St Honore
Quebec, Canada
8.1 x 2.4 x 1.6 CM (cabinet)
price: $250
May 2015

A single chisel tip Barite crystal partly jacketed in Fluorite (uncommon on these), Calcite and Pyrite crystals. Translucent, with some color zoning and a rosy core, this is a sharp example from this famed find. The Fluorites are not often seen on the Niobec Barites, these are gemmy and colorless but the pyrite adds a yellow hue to some. Nearly all of these have broken terminations as they grew on the roof of the pocket and fell off long ago. This one is nearly perfect, a slight cleave is noted on the tip as the only issue.
Cinnabar
stock #ALEC-12-063
Tongren Mine, Wanshan District, Tongren Prefecture
Guizhou, China
5.8 x 5.5 x 4.4 CM (cabinet)
price: $200
Post Tucson 2015

Twinned "drill bit" habit Cinnabar crystals on Quartz matrix with some Dolomite. A Chinese classic, for over a century Cinnabar was the only Chinese mineral seen in the western world. These were prized specimens in top collections and were the worlds best examples of the specie. Things have changed and these are no longer priceless but they are still quite fine and this habit is the most desired. Crystals to 1.8 CM most of which are fully perfect however a small one has a backside cleave not seen on display. The dark color and habit are typical of older material that is not like any of the recent finds.
Selenite
stock #ALEC-19-073
Naica Mine. Naica, Municipio de Saucillo
Chihuahua, Mexico
6.3 x 3.7 x 5.7 CM (cabinet)
price: $190
Post Tucson 2015

A cute, gem clear crystallized and esthetic Selenite from the famed Naica Mine. Crystals to 4 CM long are sharp and undamaged with perfect transparency. Selenite (Gypsum) is a common mineral but good specimens like this are rare. The photos look somewhat cloudy inside the crystals however in person they are all absolutely clear with excellent luster
Amethyst -
stock #ALEC-20-151
Statesville, Iredell County
North Carolina, United States
10.2 x 8.9 x 5 CM (cabinet)
price: $900
Post Tucson 2015

A complete deep purple colored crystal from Stateside, North Carolina showing complex stepped crystallization and distinctive zoning.Several deep solution pits are also featured in some faces that show excellent layered solution and recrystallization zones that make for attractive architecture. The large size and deep color are very fine this old locality.
Fluorite w. Pyrite
stock #17.1-AX-20-070
Ladywash Mine, Eyan
Derbyshire, England
11.4 x 9.6 x 5.9 CM (cabinet)
price: $460
Post Tucson 2015

English (Derbyshire) Fluorite with great esthetics and in fine condition. An old specimen (comes with a label from Commercial Mineral corp. vintage 1965) There are small sharp Pyrites and Calcites scattered on many faces. No mine name is on the old label but we are assured this is a fine example from the Ladywash mine in Eyan. Sharp edged zoned crystals to 6.8 CM are large for the area and overall this is an attractive Fluorite in finme shape
Cuprian Smithsonite on Willemite
stock #15.1-340
Tsumeb
Otavi-Bergland district, Oshikoto, Namibia
6.4 x 5.3 x 3 CM (cabinet)
price: $780
Post Tucson 2015

A very fine Tsumeb specimen with excellent zoned Smithsonite crystals on a contrasting matrix. This flat matrix displays well on both sides, it can be difficult to decide which is the better face to present. The "rear" has a huge stepped, etched Smithsonite crystal that is 2.4 CM across, the front shows several smaller, textbook perfect color-zoned crystals. Very esthetic and in fine condition.
Schorl and Goshenite (Colorless Beryl)
stock #Alec 14-279
Erongo Mountain, Karibib
Erongo Region, Namibia
4.9 x 4.7 x 3.2 CM (miniature)
price: $360
Post Tucson 2015

Superb clear colorless beryl (Goshenite) crystals are scattered on a series of radiating sprays of shining black Schorl. The overall effect is striking and the beryl crystals are perfectly clear. Goshenite is surprisingly rare as almost a;ll Beryl has some color. The condition of this is good overall but a few Schorl have tip damage that is seen in the photos. The Beryl however is all perfect and with glasslike luster. Classic and attractive Erongo material.
