Highly aesthetic example (my favorite I've ever seen) from this find in Pakistan. Lustrous deep green fans of Epidote with clear Quartz crystals attached and sticking straight out of the Epidote fans. This is an undamaged specimen and a near floater with many of the Epidote fans crystallized at the narrow bases too. Ex. Mike Keim.

Quartz Quartz Quartz Quartz Quartz

Large, well terminated single Quartz crystal with both Smokey and Amethyst coloration. What makes this one so special is a large 7mm bubble that travels in a 2cm wide, triangular water-filled pocket. Importantly, the pocket is not hidden deep in the crystal as many are, it's located right under the main termination display face! Undamaged and complete all around though with some angular notches on the back side where other crystals grew.

R826 - Feldspar var. Moonstone with Tourmaline  sold

Feldspar var. Moonstone with Tourmaline Feldspar var. Moonstone with Tourmaline Feldspar var. Moonstone with Tourmaline Feldspar var. Moonstone with Tourmaline

From a recent find of crystallized moonstone from Tanzania, this is easily the best example I've seen or owned. The specimen is composed of a large central crystal with a few smaller crystals above and below. These have been found here in the past, but this find has much higher quality, porcelain-like lustrous crystals than those found previously. There are also small crystals of brown Dravite Tourmaline attached. The crystals display a satiny blue 'Schiller effect' of color when turned under lighting.

Rare radial group of Leifite crystals on salmon pink Serandite crystals. The Leifite hemisphere is 2.2cm wide, lustrous and undamaged. Finding a good Leifite is hard enough, let alone one getting one on colorful pink Serandite! Ex. Gilles Haineault collection.

Gorgeous, stout Quartz crystal rising vertically from smaller crystals that adorn the base. Selected from tables of hundreds of crystals, this cluster immediately stood out as 'the one'.
