A group of beautiful quartz crystals up to 4.4 cm. The crystals are sharp and lustrous, transparent to translucent. The specimen is crystallized all-around and includes doubly-terminated crystals. In excellent condition, a couple of incomplete crystals. From the John S. White Pennsylvania Collection, and prior to that, in Robert Fender’s collection. About John S. White […]
A rare Pennsylvania locality specimen – these are sharp, transparent, brilliantly lustrous quartz crystals (up to 2.4 cm) from the Reading Anthracite Co. coal mine at Wadesville. The crystals have formed a vug within what would have originally been a larger cavity – the “roof” of the vug is is fully crystallized on top (away […]
A sharp twinned golden calcite crystal on a thin plate of small calcite crystals. The main crystal (3.9 cm) is lustrous – truly glossy, with many brilliant striations. Although the twinning is quite subtle, the composition plane is clearly visible. In excellent condition, with three edge chips. A beautiful calcite twin from the John S. […]
This is a gorgeous twinned calcite crystal – 3.9 cm, sharp and lustrous, with fantastic re-entrants. The orange hues are imparted by iron oxide on the crystal faces (this iron oxide seems to be on the surface and not inside the crystal). This calcite has beautiful internal play of light. In excellent condition, very minor […]
This is a spectacular display specimen of twinned calcite from Pennsylvania’s York Building Supply Quarry. Collecting these specimens was very difficult, as the pocket walls came apart as some were collected. This piece was collected in 2003 by one of Pennsylvania’s great field collectors, Skip Colflesh, and he repaired it in two places (down the […]
A sharp, lustrous calcite crystal perched perfectly on limestone. The 3.8 cm crystal is contact twin, with subtle re-entrants around the middle. This crystal is champagne-coloured, with orange hues added by iron oxides. In excellent condition, one nick. One place on the crystal has what seems to be a thin limestone-intergrowth veneer, and inside the […]
A classic, historic garnet from the John S. White Pennsylvania Collection – it is a parallel-growth almandine crystal intergrown around its base with additional almandine crystals. The crystals are sharp with glossy faces, and deep internal red colour. In excellent condition overall, minor chips and an area of growth interference on the top/rear of the […]
From the historic Phoenixville District, this specimen features crystallized sphalerite with quartz crystals perched on it. The sphalerite crystals are partial, with parallel stepped faces – these are sharp and lustrous. The Phoenixville District mines were worked in the 1850s and 1860s (partly driven in the 1860s by demand for lead for the Civil War), […]
This is a true American classic – a cabinet-size pyromorphite from the Wheatley Mines workings in Pennsylvania’s Phoenixville District. The Wheatley Mines were a consolidation of small mine workings on the Wheatley Lode, operated from 1851 to the mid-1860s (driven in part by the need for lead during the Civil War) and again briefly from […]
This specimen features superb sharp dodecahedral magnetite crystals from the Grace Mine. The large crystals feature the finely stepped crystal faces for which the locality is known, while some of the faces of the smaller crystals on the left side (or bottom, depending on how one chooses to orient the specimen) have only very fine […]
Detailed Description A ball of sharp and lustrous hydroxyapophyllite-(K) crystals, coloured green by chlorite inclusions. The ball is dominated by a large central crystal, while the other crystals formed as if in a rosette-type growth on either side of the central one. In excellent condition, very minor chipping as displayed, some edge wear around the […]
Detailed Description A ball of sharp, lustrous hydroxyapophyllite-(K) crystals from the Cornwall Iron Mine. These crystals are colourless, with inclusions of green chlorite. In excellent condition. This is an older specimen, with three collection numbers affixed. From the John S. White Pennsylvania Collection, he acquired it from Carter Rich. A super specimen! About John S. […]
