The crystals are translucent and reach 1.5cm in size.

There are five large crystals that comprise the group. Just a rare and spectacular piece.
T657 - Malachite on Chrysocolla after Malachite $ 1200 Katanga, Congo cabinet - 10 x 8.5 x 4 cm ![]() ![]() ![]() The Katanga region of the Democratic Republic of Congo is the Malachite capital of the world, yet most found is lapidary grade with only a small percentage (usually fibrous or stalactitc specimens) being of any interest to mineral collectors. With specimens like this, Katanga can also claim to be one of the best localities for perfectly crystallized Malachite too. This specimen features perfectly formed individual crystals to 1.3 cm on a colorful and contrasting matrix of sky blue Chrysocolla. Just fabulously sharp single crystals.The Chrysocolla has partially psuedomorphed an earlier generation of Malachite crystals.

This is a solid seam of fibrous, chatoyant Sugilite, reportedly the best quality (though not the biggest) out of only about 5 significant pieces found. A rare and unusual specimen, but could you imagine cat's-eye Sugilite cabachons? Weighs 55.6 grams.
