Super lustrous black Sphalerite crystals on contrasting crystals of Siderite. This piece is from the noted Cornish collection of Lewis Barton (his label is included), and is a superb Sphalerite from anyplace in Cornwall and likely the best known from the Ale and Cakes Mine (which is a great name for a mine)! Despite a few edge nicks and contacts the overall quality and condition is really fine. A choice addition for any good Cornish or UK suite.
Sphalerite on Dolomite -Classic USA
Pelican Mine, Picher, Tri-State District, Ottawa County
6.6 x 5.2 x 4.8 CM (cabinet)
An old Tri-state USA Sphalerite with complex twinned crystals in an intricate cluster. No damage at all, the Sphalerites are complete on all sides (which is rare) and have many distinct penetration notches and ridges. Super presentation and esthetics ex. John Buckley collection, this is far from being a "black ugly" the form is incredible.
Sphalerite - classic USA
Joplin Field, Tri State District, Jasper County
11.3 x 9 x 4.8 CM (cabinet)
Large, esthetic and in perfect condition, this is an exemplary old Tri-state Sphalerite, mined before 1940. The Joplin field was at one time a seemingly endless source of mineral specimens, though really fine, undamaged pieces were very rare. The last of these mines have all been closed for more than 50 years, and the best specimens came out long before then. This is a superb Sphalerite with large distinct crystals that stand out from the matrix. Crystal faces show complex striations, etchings and some twinning, these have a choice silky luster that shows these structures well. This is incredible in person and very much a superb piece from this now legendary area.
Sphalerite -gemmy red on Quartz
Shuikoushan Lead Zinc Mine, Changning, Hengyang Pref.
5.6 x 3.4 x 2.5 CM (small cabinet/ large miniature)
Perfect Sphalerite crystal is esthetically displayed on contrasting druzy Quartz. No damage, this is bright, sharp and far better in person, this crystal glows a rich ruby-red with backlighting, yet still looks fine under normal conditions. An older Shuikoushan specimen with outstanding luster and presence. Excellent value for a clean small cabinet specimen with character.
Sphalerite on Quartz
Clinton, Onieda County
3.5 x 2.7 x 2 CM (small miniature/ large thumbnail (toenail))
A bright lustrous Sphalerite crystal perched above a sparkling Quartz matrix. From an important 1987 find in Clinton, NY. this is an excellent clean example. The Sphalerite shows the complex form that is typical with multiple twinning and is translucent, light passing through gives a rich yellow to rootbeer color. Can be trimmed to a thumbnail if desired. A modern classic from the Northeastern USA not often available.

Gem clear crystals of honey colored Sphalerite with a few small white Calcites as accent on massive matrix. Very fine large thumbnail with fine bright luster. Better in person, these are now a modern US classic, but not often available. Ex. Hladysz collection, several crystals show pronounced smooth curved faces.

Sphalerite- gem variety Cleiophane
Ninth of September mine, Madan, Rhodope Mountains
7.9 x 5.5 x 2.7 CM (cabinet)
Worldwide mix summer
Sharp and glasslike gem Sphalerite crystals contrast with the white matrix in an esthetic combination. The Sphalerites are a dark yellow-green best seen when under strong light. The luster is brilliant. From the Madan area of Bulgaria, this zone has produced some extraordinary Sphalerites (and Galenas as well) on occasion. This piece is from a few years ago out of one incredible pocket. Far better than typical specimen with fine 3 dimensional esthetics, there is no damage at all.
