Gemmy brown Barite crystals atop drusy yellow Calcite crystals. This locality is in the Cheyenne River valley and specimens are collected from similar Pierre Shale formations as the more famous Elk Creek Barite crystals. The Barite crystals are lustrous and gemmy reaching 1.2cm in size. Many of the Barite crystals are doubly-terminated.

Stunning pink Topaz set in Calcite crystals from the famous Katlang deposit in Pakistan. The crystal is 1.3 x 1cm and transparent, gem quality. It has top glassy luster, superb clarity, and a sharply formed termination that extends into the Calcite crystals. The Topaz is undamaged and bright. Katlang Topaz, especially matrix pieces, are rare to find, and this is a beauty.

Crystallized Gold both on and in Quartz from Ballarat. The main Gold extends up the front display face, but there are also veins of Gold running throughout the Quartz matrix. Ballarat is one of Australia's most historic gold rush cities, famous for triggering the 1851 Victorian gold rush. Active Gold mining continues here today. Weighs 6.42 grams.

Crystallized Gold specimen from Statesville, North Carolina. A relatively flat specimen with excellent crystallization and bright yellow color. Displays well from either side. Weighs 0.98 grams.

Gorgeous curving masses of crystallized Gold specimen from Nevada. Excellent crystallization and bright yellow color. Displays well from either side. Weighs 2.08 grams.

Old classic crystallized Gold specimen from the historic locality of Brad, Romania. Gold mining here reportedly began in 1445 and continued up until 2006. This fine thumbnail is composed of crystallized Gold of excellent color in a sculptural formation. Weighs 1.72 grams.

Old classic crystallized Gold specimen from the historic locality of Brad, Romania. Gold mining here reportedly began in 1445 and continued up until 2006. This fine thumbnail is composed of crystallized Gold with some attached Quartz. This is from an old collection and could be further improved with additional Quartz removal. Weighs 1.85 grams.

Old classic crystallized Gold specimen from the historic Verespatak locality (the old Hungarian name) now known as Rosia Montana, Romania (the old label only lists Alba Co., so it could also be from Zlatna). The ancient gold mines in this area started more than 2000 years ago and this specimen could be hundreds of years old. This fine thumbnail is composed of crystallized with bright yellow color that displays well from on both sides. Weighs 2.21 grams.

Transparent purple and green Fluorite cubes to 6mm atop Muscovite over white Feldspar crystals.

Black matrix covered with Wavellite and crystals of Fluellite. The larger Fluellite crystals are sharp and good sized at 7mm! Fluellite is a rare phosphate mineral and the world's best were found at this old Gold mine in Nevada. Excellent thumbnail for the species!

Large blue/green Amazonite crystals set in Smokey Quartz crystals. The Amazonite crystals reach 6.5 x 4cm in size and have good coloration. This is from an old collection and could be improved with cleaning.

Water-clear single Quartz crystal with unusual form from the Mondo Mine. This recently discovered mine shot to fame for two reasons: 1) Quartz crystals of exceptional transparency and 2) a large variety of highly complex crystal forms including uncommon crystal faces, edge serations, and etched forms. This crystal has superb transparency and lots of fun surface growth features on the crystal faces. Complete all around and undamaged, a real stunner. Better than photos!

Single transparent Quartz crystal with unusual form from the Mondo Mine. This recently discovered mine shot to fame for two reasons: 1) Quartz crystals of exceptional transparency and 2) a large variety of highly complex crystal forms including uncommon crystal faces, edge serations, and etched forms. This crystal is likely the result of etching followed by recrystallization resulting multiple angular indentions up and down the prism faces. Some of the original termination faces remain intact. Well crystallized all around, even the bottom, a real stunner! A strange one for a Quartz crystal collector.

Colorful specimen of Azurite and botryoidal Malachite. The Lilyama Mine is an old Copper and Gold mine in California's Gold country, in fact it's close to Coloma, where Gold was first discovered in California. This mine has produced what is considered the best Malachite and Azurite found in the California. Collected by Jay Buscio in the 1990s.

Specimen of thick, translucent green Tarbuttite with the top crystal faces partially replaced by white Hydroxylapatite.
