This piece features brilliantly lustrous scorodite crystals from one of the world’s best localities for fine crystals of scorodite. The crystals are sharp and well-formed, translucent to transparent, and clustered together in groups and balls. In very good condition overall, a few missing crystals and chips, but this piece has impressive coverage by lots of […]

A beautiful specimen of this classic material – mimetite of the variety campylite from the Dry Gill Mine. This piece features gorgeous glossy translucent orange crystals, so lustrous that they look wet. With magnification, one can easily see the sharp, barrel-shaped, curved forms of the mimetite crystals. In excellent condition. From the Tracy Kimmel collection – […]

Sparkling tiny crystals of safflorite have replaced the silver crystals in this spectacular pseudomorph. As a result, the forms of the arborescent silver crystals have bright lustre and look super under the lights! Sharp, lustrous skutterudite crystals, including particularly around the left-hand side of the specimen (see fifth and sixth photos). From the Tracy Kimmel […]

The specimen hosts beautiful lustrous green crystals of mimetite. The crystals are sharp and barrel-shaped, exhibiting elegant curvature. Under magnification, one can see wonderful late-stage smaller mimetite crystals grown over some faces of some of the underlying crystals. In excellent condition. From the Tracy Kimmel collection – she acquired it from John Betts, whose label […]

An elongated stalactite-like cluster of bi-coloured lustrous pyromorphites from one of the world’s best localities for the mineral. The crystals are sharp, very well-formed, with some curvature. Although the main body of each crystal is a dark green with brownish and mustard hues, the terminations are all overgrown with light-green-yellow pyromorphite, some of which are […]

This specimen is from the Tracy Kimmel Collection, acquired from Jordi Fabre, and […]

This is a superb miniature – one main galena crystal with small side-car crystals, together with fantastic razor-sharp black sphalerite crystals and chalcopyrite crystals. The sphalerite crystals are lustrous and exhibit spinel-law twinning. The chalcopyrite crystals have surfaces that are almost velvety-looking. In excellent condition, no damage, only contact is around the back. This specimen […]

A true old Cornwall classic, this is a specimen made up entirely of sharp, lustrous olivenite crystals. The crystals (up to o.5 cm) are elongated, with curved faces and chisel-tip terminations. In very good condition, a few small crystals and areas are incomplete. From the Tracy Kimmel Collection (it also has two labels from older […]

A plate of glassy fluorite crystals with a featured penetration twin standing up over the rest of the fluorites. The penetration twin is an extremely light delicate lilac colour, while the rest of the crystals are colourless to perhaps the faintest blue. All of the fluorite crystals are sharp and highly lustrous. On the back/underside […]

This is a gorgeous Swiss gwindel – a nice twist, absolutely brilliant lustre (as bright as quartz gets), and great transparency. There are a couple of chips and the right-hand crystal is incomplete – one can light it so that these are not distracting – in the end, these are what make this an affordable […]

A cluster of sharp pyritohedral crystals of pyrite – from underneath, one can see that these interlocking crystals seem to have grown on a larger underlying one. In excellent condition overall – in 360 degree rotation, one can see two missing crystals and two chips – it is easily displayed in more than orientation without […]
