Azurite w. Malachite - Large classic Tsumeb.
stock #17.1-AX-5-052
Tsumeb
Otjikoto Region, Namibia
6.8 x 3.8 x 1.8 CM (cabinet)
price: $2950
Fall 2015

Very striking, esthetic, sharp and sizable Azurite with deep color and areas of Malachite alteration. In excellent condition and with textbook quality form. Despite all the many Azurites from Tsumeb over the past century, such fine examples have always been highly prized and are rarely available. Much better in person
Analcime - Classic Locale (circa 1981)
stock #15.1-550
Croft Quarry, Croft
Leicestershire, England
8.2 x 5.2 x 3.6 CM (cabinet)
price: $240
Fall 2015

Two generations of sharp and gemmy Analcime crystals in perfect condition. Ex Terry Szenics collection, these crystals range from colorless white to light pink, all have glasslike luster. There is no matrix at all, this is simply a mass of Analcime crystals in all sizes packed together. Unusual and attractive
Autunite (fine xls)
stock #17.1- A10-060
Daybreak Mine, Spokane County
Washington, United States
5.3 x 3.8 x 1.5 CM (cabinet)
price: $750
Fall 2015

An outstanding, classic Daybreak mine Autunite. Bright green to yellow green crystals in fine condition in clusters and radiating sprays. Vivid fluorescence. In excellent condition which is rare for this delicate mineral, this can be displayed from several angles. Choice.
Ferroaxinite- large compound crystals
stock #7.AE-344
Polar Urals - Tyumenskaya Oblast
Western Siberian Region, Russia
6.7 x 5.4 x 1.4 CM (cabinet)
price: $650
Fall 2015

Big and very lustrous Axinite crystals reaching 6.7 CM in size, with razor sharp edges. Transparent on the edges and translucent elsewhere, this is an older, flashy and eyecatching specimen. These have become quite rare (and very expensive) over the past decade or so, this size and quality was never common even then. Now considered a classic find, this example is a relative bargain. Some slight chipping but far less than most do and displayable without being noticable.
Wulfenite with minor Mimetite
stock #ALEC-21-050
Rowley Mine, (Reliance Mine), Theba, Painted Rock District
Arizona, United States
2.2 x 2 x 1.8 CM (thumbnail)
price: $290
Fall 2015

Well formed, esthetic and choice, these Wulfenite crystals have textbook form. From the final mining of this classic locale, this is in fine condition. A dusting of micro Mimetites and tiny balls gives some faces a slightly matte look, others are extra lustrous. A few crystals also show inclusions of the orange red Mimetite balls.
Weloganite (huge crystal) with sphalerite, quartz etc in matrix.
stock #15.1-884
Francon Quarry, Montreal
Quebec, Canada
8 x 5.8 x 4.6 CM (cabinet)
price: $8500
Fall 2015

A killer, world class and huge Weloganite, one of the largest crystals found, with exceptional display esthetics. The crystal is 4.8 CM tall. For what it is worth, this is the best cabinet matrix specimen that I have ever seen, and I prefer it to the well known published single crystals. In very good condition, the matrix is sawn on the back and base, not seen on display side. Tiny doubly terminated quartz and what seems to be Sphalerite micros with some bright golden Marcasite are noted in the vug where this grew. A few small quartz also are on the right side of the crystal just below the termination and add a little extra sparkle. Fine creamy yellow color and good luster give the Weloganite contrast from the matrix. It is very rare that we offer specimens of such stature on our website, we usually sell this quality at major shows or in private sales. This is an experiment to explore the possibility of presenting more top quality or rare specimens in this way.
Amethyst
stock #Alec 2-055
Piedras Parado, Las Vigas
Veracruz, Mexico
8.8 x 4.6 x 5.3 CM (cabinet)
price: $420
Fall 2015

Gem clear, sharp zoned Amethyst crystals in a cluster on a thin matrix sits well for display. A modern classic locale, this is an older specimen of 1970's vintage with a little different look than later finds. Excellent deep purple tips and in fine condition. Veracruz Amethysts are some of the most attractive yet affordable Quartz on the market today. Choice.
Kesterite with Mushingtonite on Quartz, Muscovite
stock #17.1-AX-15-057
Mt. Xuebaoding, Pingwu Co., Mianyang Pref.
Sichuan, China
12.2 x 8.1 x 3.4 CM (cabinet)
price: $900
Fall 2015

Esthetic and well formed Kesterites with Mushingtonite coatings in several habits are well perched on the matrix. In perfect, textbook condition this is a very fine example of this rare mineral. Before the discoveries at Xuebaoding, Kesterite was a very rare and unattractive mineral. The finds in 2002 and 2005 changed that forever. There has not been any new production for Kesterites since and the area that produced them is now a protected zone. Now scarce on the market especially in amy quality, this one is an exceptional, quality specimen that will appreciate well. Ex Sheilds Flynn collection via Bert Ottens.
