5.8 x 3.8 x 3.3 cm. A SUPER Kelly Mine smithsonite with highly lustruous, translucent Kelly blue-green botryoids. This fine piece has excellent 3-dimensioniality and is not just your flat plate.
23.5 x 15.2 x 12.8 cm. This piece is complete all around, 360 degrees, and is a wonderful, classic blue color. It consists of two generations: the underlying and more common botryoidal, rounded smithsonite; and a thin layer atop of actual CRYSTALS, rare from the locality. We call these "rice grain" smithsonites, as they are somewhat rounded. This is from the personal collection of dealer W. M. Greiger, which was purchased recently by Pala Intl. It was likely obtained in the 1950s-1960s by him though mined probably even earlier as the richness is amazing and unlike later pockets hit here.
4.6 x 4.5 x 3.0 cm. BIG, transparent crystals make this a super-desirable Tsumeb smithsonite specimen! The crystals, measuring to 1.4 cm tip-to-tip, have a light coppery color to them, and fine luster.
4.9 x 3.9 x 1.5 cm. A unique Kelly smithsonite out of the collection of William Sanborn, with massed "rice-grain" crystallization that results in a beautiful "pebbly" surface, with fine luster! Good Kelly smithsonites are hard to obtain now.
4.9 x 3.4 x 2.8 cm. A concave, hollow cast/crust of lustrous, shimmering botryoidal pink smithsonite from Reforma - this is old material, not the newer stuff from recent mining in Sinaloa at Choix.
8.3 x 5.7 x 5.3 cm. Beaverite is a rare sulfate worldwide, but is VERY RARE at Tsumeb where I believe it occurs at its best. This is a VERY RICH piece with the three sides of the specimen richly covered with canary-yellow beaverite microcrystals. The showy, 3-dimensional, vuggy front features botryoidal beaverite nestled in association with glassy, colorless smithsonite rhombs in a box-work, sulfide matrix.
8.7 x 7.3 x 4.5 cm. Translucent botryoidal smithsonite with a beautiful lavender color and shimmering luster, from Choix.
19.2 x 14.0 x 7.0 cm. An IMPRESSIVE LARGE CABINET Kelly Mine smithsonite specimen! Classic, sparkly, kelly-blue smithsonite botryoids richly cover the vuggy limestone box-work matrix. Kelly Mine smithsonites of this size and quality are seldom available and this is a GOOD one showing the natural scope of the pockets in which the smithsonite forms. Color is not bad, and lustre is high. This old piece easily dates to the 60s or 70s. Ex. Russell Jones Collection.
8.7 x 6.8 x 5.7 cm. A WEIRD, UNUSUAL, but SHOWY Tsumeb combination specimen! Brick-red cuprite of the variety chalcotrichite encrusts a vug lined with sparkly, cream-colored, botryoidal smithsonite in mostly massive smithsonite matrix. Chalcotrichite is RARE at Tsumeb and I have never seen a robust variety of chalcotrichite like this before - usuaully they are isolated needles! Certainly a RARE varietal. Ex. Rob Smith Collection.
4.9 x 4.4 x 3.9 cm. A "Kelly"-colored botryoidal smithsonite, not from Kelly, but from the older finds (not the recent ones) at Choix.
8.4 x 5.9 x 4.9 cm. A rich specimen of caramel-colored rhombs of smithsonite on contrasting white matrix, from what is arguably the greatest worldwide mineral locality of all time, which produced smithsonites in a great variety of colors and forms. Ex. Rob Smith Collection.
16.4 x 12.5 x 9.9 cm. A huge specimen completely covered with sparkling crystals of smithsonite, from Tsumeb! Tsumeb smithsonite came in a great variety of colors and forms, depending on the composition of the pocket solutions -- this one has grayish-tan crystals of an entirely different form than the more typical rhombs of the other specimen. The matrix here is a complex structure of sheets and protuberances, giving this large specimen quite a sculptural quality. It is covered all over with crystals; the only contact is on part of the underside, indicating that this matrix stuck out into the pocket and was exposed all over, allowing crystals to form everywhere on it. Ex. Rob Smith collection.
9.4 x 8.4 x 4.4 cm. Here is a stunning and large plate of Kelly Mine smithsonite - once abundant, now sadly hard to get. This specimen has the gorgeous blue-green color these smithsonites are famous for - and rather than being strictly botryoidal, the surface has little curved crystal faces on it, so it actually sparkles. Ex. Russell Jones collection.
8.9 x 6.6 x 4.9 cm. From the collection of Evan Jones, a gorgeous smithsonite specimen from a mine better known for its purple fluorites. Honestly, this smithsonite easily rivals a fine Kelly Mine one, with the only difference being a shift more towards green from blue. The massed botryoidal forms shimmer like silk, and the fact that they are clustered in isolation on the underlying matrix adds a really pretty "framing" for them.
7.5 x 5.0 x 3.6 cm. Luscious, lustrous, apple-green cuprian smithsonite crystals richly cover matrix on this striking Tsumeb specimen. This color of green cuprian smithsonite is one of the most desirable and uncommon smithsonite varietals from this famous and now-closed mine. The matrix includes baryte and calcite, so we also have a very fine Tsumeb combination specimen. Ex. Skip Colflesh Collection.
