A one-of-a-kind specimen from the John S. White quartz collection. This is an elegant, curved and twisted stalactite-like chalcedony, from the Paraiba district. It is a tall specimen and graced John’s main quartz display case. In excellent condition, there is one small missing side tip low on the piece, and there are two repairs to […]

Detailed Description A highly-etched Navegadora Mine spessartine, with recrystallization patterns. This thumbnail-sized crystal is a neat shape and exhibits dodecahedral-crystal face angles in its crystal surface patterns. This crystal glows deep red when strongly lit from behind (for example with a phone light). In excellent condition, a couple of tiny chips on the backside. From […]

Detailed Description A highly-etched, lustrous Navegadora  Mine spessartine, with recrystallization patterns. Despite the etching, one can discern the angles of dodecahedral faces among the recrystallized surfaces. This crystal glows deep red when strongly lit from behind (for example with a phone light). In excellent condition, a couple of tiny chips. From the John S. White […]

Detailed Description A highly-etched Navegadora spessartine, with minor recrystallization patterns, and such an unusual shape for any garnet crystal. This crystal glows deep red when strongly lit from behind (for example with a phone light). In very good condition, minor chipping. Truly, a unique spessartine! From the John S. White Collection – he had a […]

A sharp dark green elbaite crystal with a beautiful termination from the Cruzeiro Mine. The crystal has good lustre, fine straitions and complex termination faces. The colour is very dark, but clearly visible in good light. In excellent condition, no damage and stands perfectly for display as photographed. A great tourmaline at a great price! […]

A beautiful sharp, glassy tourmaline from the John S. White collection with an important story to tell. This elbaite crystal formed first as a pink crystal and subsequently as the crystal grew, the crystal continued its growth as a green and slightly aqua-hued crystal (due to minor changes in the composition of the substrate from […]

This is a gorgeous Irai calcite – it really stands out. There are two generations of calcite crystals – the larger first generation crystals have phantoms, while the second generation crystals are smaller, perched around and on the bases of the first generation crystals. It is a dramatic specimen, with great proportions. Glows orange under […]

This little mountain peak of beautiful amethyst crystals formed over a sharp calcite crystal. The calcite is no longer present, so this specimen is completely hollow – inside the hollow (shown in the fourth photo), one can easily see the well-defined forms of the calcite crystal, where it used to be. The amethyst crystals are […]

A large, showy specimen of amethyst from the John S. White collection. It is comprised of amethyst “flowers”, with sharp, lustrous crystals. A challenge to capture, in a photo, how great this piece is  – I’ve tried to convey the translucence in the second, fourth and fifth photos, and the lustre in the sixth and […]

A gorgeous grouping of quartz crystals with a dusting of microscopic marcasite selectively deposited on the edges of the terminal faces. In excellent condition, tiny imperfections. A killer from the John White quartz collection, originally from the Bill & Carol Smith collection (with labels from John, Dave Bunk and Peter Sztacho) . About John S. White […]

A wonderful large sliced and polished cross-section of a quartz crystal, full of sharp tourmaline crystals and accented with bright red hematite inclusions. The tourmaline crystals have not been analyzed – upon examination with magnification, some are green and some have brown hues, while some appear black. (Please note, if you zoom in and see […]

This quartz crystal contains two internal spaces with moving inclusions. The first is a flattened triangular space in which a black bubble moves (it travels around the triangular area as the crystal is rotated). A moving black bubble in a quartz crystal is not at all common. The second is a larger space in which […]
