Emerald green crystals of Dioptase from the Congo. A fine thumbnail composed of a single large crystal with a smaller doubly-terminated crystal attached to the side.

Cluster of bright, translucent, deep emerald green crystals of Dioptase from the Congo. Nothing but solid Dioptase without matrix, with individual crystals to 2cm!

Large single octahedral Scheelite crystal from China. There is a small amount of attached Muscovite on one side, otherwise it's all Scheelite. Undamaged with good transparency, especially at the tip.

Fine quality Hemimorphite specimen from an obscure locality in Utah. This is a floater specimen well crystalized all around with White Calcite crystals are present on one side. Lustrous and translucent, high quality crystals all around. Neat and uncommon locality specimen that comes with an old Don Olson label.

Glassy blue Aquamarine crystal with Muscovite from Chumar Bakhoor in Pakistan. The Aquamarine is 4.5cm wide and highly transparent and presents well for a wonderful display specimen. Pristine and undamaged.

Unusual Roselite specimen featuring mound-like, hemispherical clusters of magenta Roselite crystals over Calcite crystals. Large sized Roselite specimens with this amount of crystal coverage are uncommon and makes for a spectacular display piece, despite light damage to the crystals. Sawcut on one side.

Outstanding cluster of blue Celestite from the Maybee Quarry in Michigan. The cluster is composed of doubly-terminated crystals and the main crystal a superb one measuring 6.2 x 3.8 cm in size. The crystals have transparency and are in excellent conditiion with only a couple very trival edge nicks to be found. A USA classic.

Classic and now hard to find specimen of 'raspberry' Grossular garnets in matrix. The dodecahedral crystals measure up to 1.7cm across. There are also tan Vesuvianite present and partial Grossular crystals that display the color zoning inside. These were first found in 1974 and initially sold as coming from Lake Jaco, but the garnets are actually found in the Sierra de Cruces range located east of Lake Jaco in the State of Coahuila.

Tabular hexagonal prisms of Mimetite on matrix from the Mount Bonnie Mine. These are beautiful crystals to 1.2cm wide. The crystals are a translucent yellow but are partially coated with green Duftite giving an overall yellow/green coloration. This locality is closed and these are hard to find now, especially the less common ones with so much Duftite.

Bubbly mounds of yellow Mimetite from Mapimi. Great coverage of undamaged, botryoidal Mimetite with scattered crystals of Hemimorphite.

Scalenohedral Calcite crystals that have been pseudomorphed to golden colored Smithsonite. These are unusual specimens that are no longer being found. A high quality, undamaged example of this find.

Stark white starburst formation of Colemanite on a sparkling, cream-colored Calcite matrix. The Colemanite cluster is 4cm in size and perfect. So many Colemanite specimens are 'boring' dense clusters of similar sized crystals - this well isolated starburst really stands out and is exceptional.

Amethyst casts after rhombic Calcite crystals. The former Calcite crystals have dissolved away leaving angular, hollow casts of sparkling purple Quartz.
