5.0 x 3. x 2.7 cm. This is a fine specimen of Hubnerite from this classic Bolivian locality. There are several sharp, lustrous, stubby, black (a very slight red color will appear with strong lighting) crystals of Hubnerite beautifully oriented and intergrown with gemmy Quartz crystals on matrix.
3.3 x 2.4 x 1.9 cm. This particular specimen consists of several fine, sharp, highly lustrous, black-brown cyclic twinned crystals on gem Quartz matrix.
3.1 x 2.5 x 2.2 cm. This is a superb specimen of a rare phosphate from a world-famous locality. Zanazziite is a Hydrated Calcium Magnesium Iron Aluminum Beryllium Phosphate.

9.5 x 6.5 x 4.8 cm. An impressive and colorful rhodochrosite specimen from the famous N’Chwaning II Mine. Super gemmy and lustrous, intergrown, cherry-red rhodochrosite scalenohedrons densely cover the thin matrix rind of massive manganite. The rhodochrosite crystals are partially covered by a quartz druse. The gemmy rhodochrosites reach 2.0 cm on this specimen.
