A sparkling jumble of intergrown, doubly-terminated quartz crystals. These crystals are sharp with bright lustre and with neat inclusions. The main portion of each of the crystals contains a lighter-coloured textured inclusion, with a dark green inclusion closer to a few terminations on the piece. A cool specimen from the John S. White collection. About […]

This piece features slender, delicate pale lavender amethyst crystals rising up from a plate of smaller jumbled crystals. These amethyst crystals are quite curious and complex, under magnification – each  exhibiting the faces of more than one individual. They appear intergrown, almost as if twinned (although there is no twinning law to account for it […]

This specimen combines quartz crystals with balls of bladed hematite crystals. The quartz crystals are superb examples of  “growth-inhibited” or “interrupted-growth” crystals. As the quartz crystals grew, hematite periodically interfered and interrupted the growth of perfect quartz crystals. However, for several of these crystals the interference was only partial, allowing the quartz crystals to resume […]

A superb quartz flower from Irai. Forming in thin seams in the basalt, these quartz flowers often have very limited room to grow and therefore crystallize outward from a central point along a relatively flat plane. This specimen has fantastic lustre, good transparency, and the crystals are terminated all around. In excellent condition, a wonderful […]

Beautiful amethyst crystals on calcite from Osilo. These crystals are sharp, lustrous and transparent. Some show a reverse-sceptre habit. They have very good colour, contrasting beautifully with the pale green calcite crystals upon which they are perched. In excellent condition, a very fine Italian amethyst from the John White collection. About John S. White (click […]

The quartz crystals on this faden quartz specimen formed along two major separate faden lines, so the piece is essentially made up of two faden quartz growths, with some smaller quartz crystals in the middle that follow a third small faden line. The crystals are sharp and lustrous. In excellent condition, no damage except right […]

This is a quartz epimorph – a fully-crystallized quartz mold that grew over fluorite or anhydrite, which subsequently dissolved. Every surface of this piece is crystallized with quartz crystal faces, including the thin edges, so whatever process caused this to detach from its original growth position, it happened before the crystallization was complete. In excellent […]

A cluster of beautiful Tessin habit quartz crystals with chlorite inclusions from the Himalayas. Within the crystals, the chlorite inclusion is a narrow strip, while the rest of each crystal is clear (one can see this in the photos of three different angles of the main crystal, rotated one to the next). This is an […]

The box-like chambers of this specimen are quartz, var. chalcedony, replacing coral. The front of this specimen is a cut and polished surface.Each of the chambers has a final growth of sparkling quartz microcrystals lining them, except for the one on the right. These sparkling crystals – and the contrast with the chamber that doesn’t […]

A doubly-terminated Tessin habit quartz crystal, with some smaller sidecar crystals, from the Idarado Mine. The crystal surfaces have some frosting, while the crystals have some transparency at either end (seen when backlit). In excellent condition, a fine Colorado quartz from the John White quartz collection. About John S. White (click here)

A gorgeous sculptural piece from the John White quartz collection, this is a chalcedony pseudo-stalactite coated with deep purple amethyst crystals. The base is a saw cut so it stands perfectly for display. In very good condition, minor incomplete crystals. A beauty! About John S. White (click here)

This piece is so great when you examine it closely – the crystals feature sharp phantoms of sparkling red hematite. Many of the crystals are water-clear, making it easy to see the phantoms. The crystals have great glassy lustre and sparkle. In excellent condition. A beautiful cluster of quartz phantoms from the John White quartz […]
