An important United States gold specimen: Gold from this small mine near Boise was found in this quality only once in a spectacular, small lucky find of around 2005 (with ametal detector on the old dumps). This specimen is one of the largest and finest known from the find, and was in the collection... Click For More Information

The photos tell the story here, but for a bit of context: Few large matrix tanzanites exist, particularly in this size. The single crystal is 17 cm tall and perched in calcite. It is an astonishing and rare example of tanzanite with unusual pseudocubic crystals of prehnite, just as a bonus to the hu... Click For More Information

The North Carolina emerald mines are an important part of US gem lore, having been visited and worked by the great Tiffany's gemologist Kunz in the early 1900s. Intermittent production continued for 100 years, but pockets of good crystals have been an EXTREME rarity. At 281 grams and with no repairs... Click For More Information

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

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

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...
