Classic Cumbria sphalerite, one would think at first....but I am told that when on the quartz and isolated in this style, it is actually a typical old Derbyshire association. This piece is beautiful , regardless, for the sharp isolated lustrous crystals (to 1 cm) on sparkling quartz background.

Sphalerite from Neudorf, Saxony-Anhalt, Germany [db_pics/pics/oldeuro-84b.jpg]

This is a GORGEOUS specimen where every one of the three species, sparkles brightly. The contrast, with the quartz vein winding over the sphalerite, and accented by golden siderite, is striking. This large specimen is nearly pristine except for only a few very trivial bits of wear, and is a a choice example of this assemblage from a classic old locality. But you rarely see the combination so well presented. Beautiful - better in person!

A large plate of sparkling, very lustrous , sphalerite from this classic old district, probably from the early to mid 1800s. It is very nearly pristine despite its large size, and presetns well. Old classic!

Composed of unusually thickly-interwoven, lustrous, brassy yellow crystals of pyyrhotite to 6.5 cm on edge, this specimen also is decorated by a few lustrous black sphalerite crystals to 1 cm across. In addition, the whole specimen is studded with rounded aggregates of rhombohedral, tan siderite, to 5 mm across. Nice color contrast, and a sharp metallic, carved look to it, make this piece stand out. As well, it is HUGE for this old classic locale! This monster classic weighs 7.5 pounds!

A sharp, lustrous, translucent sphalerite crystal with a golden-green hue to it, perched in classic Westfield matrix of quartz and prehnite. Sphalerite is rare for this locality and this is a beautiful specimen, as well.

Sphalerite (twinned!) on Dolomite from Old Tri-State Mining District, Treece, Kansas, USA [db_pics/pics/pb55b.jpg]

This is absolutely one of the nicest specimens I have seen from this venerable old mining district. If i had to guess based on past experience driving through the midwest, I'd guess it to be from the Cherokee Mine. A huge, coal-black, doubly-terminated, twinned crystal of sphalerite, over 2 INCHES or 5 CM in length, is aesthetically perched on a matrix! The matirx is not your usual rock, but rather is cyrstallized , made up of saddle-shaped crystals of dolomite to 1.0 cm across, upon which are scattered iridescent crystals of chalcopyrite. Considering that this locality has been closed for going on 40-plus years, this is indeed a special specimen!

ex. Dr. Werner Paar Collection Nagyagite is one of those romantic old European rarities because it is mineralogically and historically interesting, both. This is a very large, rich plate with FREESTANDING (unetched from calcite!) crystals to 4mm of this very rare species, from its type locality, richly scattered over a matrix composed of sphalerite with decorative pale pink rhodochrosite accent. It is important that this has not been etched out from calcite as with so many nagyagite specimens, as that preparation method changes the natural patina on the surface of the crystals. These are rather robust, stubby crystals, nicely interspersed with rhodochrosite aggregates on ore matrix. (TYPE LOCALITY)

Just a stunning Dalnegorsk combo specimen. The calcites not only have wonderfully sharp poker-chip form, but a lovely pastel pink color from manganese. They sit on a beautifully contrasting matrix of dark crystallized sphalerite. The calcites are actually like little sandwiches, transparent in the middle and milky-translucent on the faces. Fluorescent orange.

This has, like the above, a bit of sentimental history for me. It is a piece I have known about and followed for a long time, and always regarded as one of the finest for its type, if not the biggest or most expensive out there. I finally own it now, from the Ed David collection. He had bought it from Collectors Edge in 1997 when it came out of Steve Neely's incredibly fine and noted Elmwood collection suite. It features three gorgesou, colorful crystals to 2 inches (5 cm) on edge, perched gracefully and isolated on contrasting sphalerite matrix. The sphalerite is in turn perched upon a shard of dolomite rock that becomes a perfect natural pedestal for the piece as displayed on a custom lucite base we have made for it. Moreover, the style of the fluorites is worth commenting on. This type, with the glassy smooth corners , is among the rarest style of Elmwood fluorite to find on matrix and truly oustanding specimens like this one are few and far between! This one was already owned in the last 15 years by two of the great collectors of our time, both good friends of mine. I would love to see it find a third home and continue to add to its pedigree! The pics do not convey, by the way, the brilliant sparkle and lustre of the underlaying sphalerite knoll. BETTER AND MORE 3-DIMENSIONAL IN PERSON!

T06-334 - Sphalerite (twinned) on Quartz - SOLD

A matrix of lustrous, colorless, quartz crystals, to .6 cm in length, is the host for a superb, lustrous, translucent, amber yellow, doubly terminated, sphalerite crystal, which measures 3.0 cm across. The aesthetics of the specimen are wonderful. This deposit is much better known for its world class copper and silver specimens. These very rare gem crystals came out in the 1980s. FEW gemmy sphalerites, twinned no less, are of this size! I have not seen a good one for sale in a long time.

A vivid, colorful piece with unusual aesthetics, comprised of sharp red rhodo rhombohedra draping over small, sparkly quartz sprays, themselves perched on teh edge of a large twinned sphalerite. The overall composition is really striking!
