Rare classic Elbaite crystal from the Hyakule Mine in Nepal. These Nepalese crystals are distinctive and now very hard to find, and this one is both good sized (many being thin 'pencil' style crystals) and highly transparent. The termination is green while the rest of the crystal is pink with bands of lighter and darker coloration. It's complete and undamaged except for one chip on the back. There are also some small Tourmaline crystals attached to part of the backside. Comes with an old Joe Cilen label with his hand drawn picture and description on the back. This is a great piece and better than photos - you will love this when you see it! Weighs 23 grams. 

The only way to describe this specimen is to say it's an absolute jewel!  Doubly-terminated Calcite crystal from the Elmwood Mine in Tennessee. This is a stunning, pristine crystal with golden coloration that deepens near the terminations. Though Calcite is not a rare mineral, even as very large crystals, they are difficult to find in the quality. A competition level miniature. Like a faceted jewel made by the earth.

Large, deep blue crystals of Benitoite on matrix. With crystals to 2.2cm, this is a visually impactful miniature sized Benitoite specimen. The crystals have strong blue color, lustrous faces, and are thick. The top of the large crystal has significant gem value (have you checked the price of Benitoite gemstones lately?).

Crystallized Gold in Quartz from the Reed Mine in North Carolina. The Reed Mine was the site of the first documented Gold find in the United States when in 1779, 12-year-old Conrad Reed discovered a 17-pound gold nugget in Little Meadow Creek. Conrad's father John Reed later found a 28 pound Gold nugget. After the placer Gold was exhausted, the mine was advanced underground. This specimen was recovered during the underground workings. It's a rich and showy Gold specimen and an interesting piece of history as well as a hard to find Gold locality specimen.

Blocky, electric blue crystals of Azurite from the historic mines in Bisbee, Arizona. The Azurite occurs as a thin veneer over Malachite after Azurite pseudomorphs, giving the specimen the bright electric blue coloration. This classic Azurite is similar in appearance to specimens from the Milpillas Mine in Mexico. Areas where the Azurite does not cover the underlying Malachite is natural growth formation and adds to the visual appeal. It's well crystallized all around, even on the bottom.

Transparent Calcite crystals on hoppered orange Vanadinite crystals from San Carlos, Mexico. A very sculptural, high quality miniature sized specimen. These are very uncommon in this quality.

Gem quality pink Tourmaline crystal from the Himalaya Mine in San Diego Co., California. The crystal is transparent from top to bottom and accented by purple Lepidolite and thin blades of Albite. Pristine and complete crystal of the highest quality. As a California mineral dealer I've seen hundreds and hundreds of Himalaya Mine Tourmaline, and this one is in the top 1 percent. Weighs 18.4 grams. 

Transparent multi-colored Tourmaline crystal from the Xanda Mine in Brazil. This gem crystal has a steep pyramidal termination and grades up from a green base to a central blue zone followed by a purply pink termination. It's complete all around, transparent top to bottom, and pristine. The blue zone is really impressive. Ex. Stan Korfmacher  collection. Weighs 9.87 grams.

Long before China, transparent Cassiterite from Bolivia was the standard and this one will not disappoint. Cassiterite specimens from this locality are most commonly found as densely packed groups of crystals. This specimen features a large, single, isolated Cassiterite crystal on a matrix covered by Quartz and Siderite crystals with a single Quartz crystal rising dramatically from the back. The Cassiterite crystal has it all - transparency, good size (2cm), and high luster. It's also complete all around and undamaged.
