Kelly Mine (Tri Bullion shaft; Paschal shaft; Traylor shaft; Kelly tunnel)
    Magdalena District, Socorro Co.
    New Mexico, USA

    This Smithsonite features a nice spattering of "rice grain" crystals atop its subtly botryoidal powder blue surface. These bonus elements have a gentle silky luster adding to the overall appeal. From the famous Kelly Mine in New Mexico, this is a classic example from a classic locality. The presence of Copper salt results in the attractive sea blue coloration. Top quality Smithsonite of this hue is known only from the Kelly Mine, and those deposits were exhausted by 1931. The lovely turquoise blue material has formed alongside Limestone and rests on top a Limestone matrix. Collector number "26722" appears on the bottom, and the robust specimen comes with a custom acrylic base. Specimens of this type are becoming harder and harder to find.
