From the Marty Lewadny collection, a sensational quartz specimen, not common from the Daye Mine. It has two intergrown, very gemmy, TABULAR quartz crystals growing in one direction, and a single one growing in the opposite one. Sticking out from the middle of both are two conventionally-formed crystals! 5.5 x 4.6 x 2.0 cm
Classic Thunder Bay material, deep purple crystals speckled with little bright rust-colored inclusions of hematite. From the collection of Canadian collector Marty Lewadny. 6.0 x 4.8 x 2.7 cm
This is a specimen of solid chrysocolla, from the historic Miami Mine (copper) in Arizona, which has been producing for almost a hundred years. Between two layers of chrysocolla is a pocket in which sparkly quartz has coated the chrysocolla. Very rich old specimen! 10.4 x 6.0 x 5.2 cm
Much more familiar from Pakistan - this is a Brazilian faden quartz, very gemmy and with the typical tabular form of fadens. It is complete and terminated all the way around! Even the one small area that was the original contact is now healed with micro-faces, as it came loose in the pocket. Razor-sharp faces everywhere. 8.2 x 4.5 x 1.1 cm
A specimen of natural ametrine (not heated to create citrine), with about an even balance of yellow citrine and purple amethyst. Good lapidary material, or keep it as a specimen - as although it is naturally etched, it still shows faces. 8.0 x 5.5 x 3.4 cm
You have seen vivianites and sulfurs coming from Bolivia, but NOT superb smoky quartz specimens such as this one from a gold mining operation there! These are gemmy, silky crystals with blushes of smoky color inside, It is a fine, large and beautiful cluster, for Bolivia or anywhere! 11.3 x 8.4 x 6.6 cm
A gorgeous, gemmy, compound crystal of fluorite (2 cm) with a sharp phantom inside, starkly isolated on a cluster of quartz crystals. The isolation of this pretty crystal makes this specimen really dramatic and special! 9.0 x 7.8 x 4.8 cm
An OLD-TIME, CLASSIC rhodochrosite CABINET specimen from an UNCOMMON Colorado locality - the Argo Tunnel near Silverton. Lustrous, salmon-pink rhodo rhombs to 6 mm richly cover the vug and surface of the drusy quartz-covered matrix. Three older labels come with this fine old-timer, mined around 1900. What a piece of history! 11.5 x 10.4 x 7.7 cm
A SUPERB, AESTHETIC and PRISTINE cluster of translucent, purple and green fluorite octohedrons to 3.5 cm on quartz matrix from the famed De An Mine of China. Common a couple of years ago, supplies have dried up and disappeared, with very little new material coming out. 7.2 x 4.8 x 4.3 cm
A VERY RICH, OLD-TIME specimen of native lead with quartz from the classic locality for native lead - Langban, Sweden. One face has been sliced and polished to show the lead. 5.2 x 4.6 x 4.4 cm
An AESTHETIC and UNCOMMON combination CABINET plate from the Tongbei Area of China. Very gemmy and lustrous orange spessartine garnets to 6 mm richly cover matrix along with lustrous, smoky quartz crystals and one, frosted, very light green fluorite octohedron. A couple of broken smoky crystals are barely noticeable and are certainly not detracting. Very few of these spessartine/fluorite combo pieces have come from Tongbei. The back and one side has been sawed to enhance display. 10.9 x 5.4 x 2.8 cm
A CLASSIC, OLD-TIME and excellent specimen of sparkly, teal-colored scorodite crystals richly lining a T-shaped vug in quartz matrix with a couple sprays of goethite blades. This fine old piece hails from the well-known and abandoned Hemerdon Bal open-cast mine of Devon, England and is the source of probably Europe"s finest scorodite in modern times. 4.4 x 4.1 x 3.3 cm
An aesthetic and pristine CABINET bow tie of lustrous, transparent amethyst crystals from Guerrero, Mexico. One end looks like citrine, but is actually the bit of gossan matrix showing through the clear termination. A very showy piece. 10.6 x 2.2 x 2.2 cm
A showy thumbnail of a gemmy and lustrous, cherry-red proustite crystal nicely accented by sprays of milky-white quartz needles from the famous Uchucchacua Mine of Peru. The face and three sides are well-crystallized. 1.5 x 1.5 x 1.2 cm
A GLORIOUS and STRIKING miniature of a lustrous, striated, dark green tourmaline set at the base of a cluster of VERY GLASSY, SCEPTERED, smoky quartz crystals from Pakistan. Super-trivial edge bruises in a few places are barely noticeable. Sceptered smoky quartz with tourmaline of this quality is UNCOMMON from Pakistan. 4.6 x 3.8 x 2.8 cm
