Detailed Description A parallel-growth trapezohedral andradite crystal from the Cornwall Iron Mine. The crystal is dark brown and exhibits some growth inhibition, as it interacted with the substrate in which it formed. In excellent condition, one incomplete area on the back of the piece. From the John S. White Pennsylvania Collection, acquired from his good […]

Detailed Description A textbook trapezohedral andradite from the famous Cornwall Iron Mine. This is a sharp little crystal with striations. It is crystallized all-around, with a bit of matrix contact on the underside – in excellent condition. A beautiful garnet crystal from the John S. White Pennsylvania Collection. About John S. White About the Cornwall […]

Detailed Description This is a remarkable Jeykll and Hyde andradite crystal – I’ve never seen one like it. It is comprised of dodecahedral and trapezohedral crystal forms. However, viewed from one side, it appears to be essentially a dodecahedron (with minor modifications), and from the other side it is a trapezohedron with almost no sign […]

Detailed Description This piece features two main andradite crystals (up to 2.4 cm) from the classic Cornwall Iron Mine. One crystal is predominantly dodecahedral, with small trapezohedral modification faces. The other crystal is a parallel-growth composite exhibiting only trapezohedral forms.  Even more fascinating is that upon examination with magnification, the dodecahedral crystal has trapezohedral crystals, […]

This is a fantastic celestine crystal from the famous Pennsylvania locality, Meckley’s Quarry.  It is doubly-terminated, sitting well up off the matrix, and is a textbook orthorhombic prism. It has good blue colour, in particular in a central zoned band down the middle of the crystal. The sharp crystal  measures 2.8 cm, and has glassy […]

Intergrown blocky crystals of blue celestine from the classic Pennsylvania celestine locality, Meckley’s Quarry (production at Meckley’s commenced in 1936). These crystals are well-formed, with good lustre and an intricate crystallization pattern at the termination faces. In excellent condition overall, two chips (one is the white spot visible in the first photo). A very fine […]

This quartz specimen is an exquisite green, thanks to underlying and included malachite. The original larger generation crystals are accompanied by – and some partly overgrown by – a second generation of smaller quartz crystals, many of which are green thanks to included malachite. The quartz crystals (both generations) are sharp and lustrous. In excellent […]

Detailed Description A gorgeous specimen featuring sharp crystals that combine the classic Thunder Bay amethyst colours of medium-purple and vivd hematite-red. The lustre is so high that the specimen looks wet. This piece was found in the clay within a collapsed pocket – it was detached from the rock during the brecciation of the final […]

A beautiful flower-like group of arsenopyrite crystals from Panasqueira. These crystals are silver with a faint blue irridesence and bright metallic lustre. The crystals (up to about 2 cm) are striated and have complex stepped edges, like a “cockscomb” or serrated surface. In excellent condition. From the Tracy Kimmel collection (and has an accompanying Crystal […]

This is an incredibly aesthetic arsenopyrite specimen – it is a complete cluster of sharp, lustrous arsenopyrite crystals, sitting on a bed of pale rhodochrosite and surrounded by a ring of lustrous black sphalerite crystals. The arsenopyrite is in perfect condition. Many of the sphalerite crystals are complete as well – some sphalerites are not […]

This is a mimetite of the highest quality from Tsumeb. It features sharp, incredibly lustrous hexagonal dipyramids of yellow translucent-to-transparent mimetite. In excellent condition, with minor calcite in association. From the Tracy Kimmel collection, this specimen was collected in 1982. It was formerly in the Desmond Sacco collection and Tracy then acquired it from Jordi […]
