Fine quality single crystal of Malachite after Azurite from Milpillas. This truely looks more like a Malachite after Tanzanite than what it is - it has such an unusal shape. The single 3.5cm tall crystal is visually striking against the white matrix and in perfect condition. The chatoyancy of the velvety Malachite is wonderful with a uniform wave of light rolling up to the termination as you turn it in your hand. There is a small amount of remaining Azurite around the base of the crystal. Unique crystal that is by far the best pseudomorph from Milpillas I've ever owned.

Gem Tourmaline crystal recently mined from the famous St. Anne's Mine in the Karoi district of Zimbabwe. Fully terminated, complete, and undamaged. It's transparent top to bottom with a good medium green color over most of the crystal with a darker green (though still transparent) termination. The termination is multi-faceted and complex. Excellent quality Tourmaline, internally flawless. Weighs 6.92 grams.

Lavender crystals of Creedite from the Hall Mine in Nevada. Lustrous and transparent, high quality crystals.

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.

Bright metallic grey crystals of Gersdorffite from Morocco.  Fine quality crystals of Gersdorffite and a great display specimn for the species with bright green Annabergite adding good color contrast.

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.

Fantastic single Chrome Tourmaline from Tanzania. 'Chrome Tourmaline' is a vanandium and chromium rich variety of the species Dravite. This crystal has 3 distinct color zones - a bright, vivid green at the termination, a darker green at the center, and a yellow green at the base. This is one of about 5 similar crystals I purchased years ago and I've never seen another similar since then. Weighs 35 grams.
