Pentagonite is the rare (very much so) dimorph of Cavansite. This means that they are the same chemistry but are actually different crystal forms, and tus different species. As rare as pentagonite is (the first Indian specimens were only found many years after the first cavansites), it is even more... Click For More Information

This specimen exemplifies the best qualities of the pocket, nicknamed the "wheatsheaves pocket," and was found circa 1980. The luster is fantastic, and the color is a rich cherry red. It just "sparkles" like few other minerals ever do. The piece is complete all around the periphery and without damag... Click For More Information

The photos say it all: Liddicoatite from Madagascar is well known for the magnificent complex multicolored growth patterns, but this is the most spectacular matrix example I have seen of this style. The piece is complete 360 degrees, and perfect (with a few repairs). The matrix is a gorgeous pearles... Click For More Information

Most tanzanite crystals, for whatever reasons of science and geology, form as "singles." A double, especially a cluster as balanced and symmetric as this, is extraordinarily rare in the mineral world. This piece is complete all around, 360 degrees. It is not the most gemmy, although it is translu... Click For More Information

Milpillas produced a flood of azurites in the recent heyday there, mostly 2009-2013. However, the flood has tapered, and the styles have changed over the years. This piece is of what I would call a "classic style" from the midrange of production, with large, robust crystals of the brightest azure bl... Click For More Information

Wulfenites from this mine are still common on the market, but NOT in quality. This piece is complete all around, with superb, sharp crystals of the highest luster and color. They are large, as well, to 4 cm. From the mid-1970s finds, this is a stunning small cabinet piece that was formerly in the... Click For More Information

A superb prehnite that is certainly one of the finest examples of this find, and a contender for among the best of species in my opinion. This was purchased from the collection of Rock Currier in a small group of Mali prehnites he let go to me before he passed away. He and a partner controlled ne... Click For More Information

An incredible large specimen weighing about 9 pounds with intense sea foam BLUE color. This is the classic color of really old Brazilian aquas, recovered in the 1920s-1950s primarily. Many of them were cut for gems and lapidary carving. Much of the best work was done in Idar-Oberstein. It is a mi... Click For More Information

These treasured red jewels from the late 1970s and early 1980s finds here only turn up in old collections. This is a very balanced, 3-dimensional miniature with superb aesthetics and the best rich, cherry-red color. Unlike most of them which are rather damaged (due to the time they were collected, g...

I think the photos speak for themselves, although this is even better in person. It is an intensely colorful specimen with hot yellow cubes as sharp as you could dream of, and highlighted by purple phantoms around their edges. It looks like cubic mushrooms shooting up - it is very 3-dimensional.... Click For More Information
