Detailed Description This is one of the best, highest-quality cabinet-sized sceptres I’ve seen from the Chibuku Mine – it has intense deep purple zones along the edges of the pyramidal faces, and the rest of the sceptre head is a combination of smoky and amethystine quartz. It has super lustre, and three of the pyramidal […]

Detailed Description This specimen hosts groups of sharp microcrystals of ruizite. This is a very uncommon mineral, rarely forming sharp, distinct crystals. However, in 2008, a single boulder at the Cornwall Iron Mine produced excellent micro crystals, collected by Skip Colflesh and Scott Snavely. These ruizite crystals have nice red-brown colour and there are good […]

This specimen hosts sharp tapered micro crystals of wurtzite to approximately 2 mm in length. In excellent condition, a couple of incomplete crystals on the right-hand side of the crystal groupings. This is a rare locality piece from a coal mining area in Elk Co., Pennsylvania, where operations date back to the  late 19th century. […]

This specimen features a sharp, lustrous 2.7 cm pyrite crystal in phyllite, collected by Herb Corbett in 1968. It’s a figured piece, in Rocks & Minerals Vol. 87, No. 2: 181, in John White’s very first Mineral Mysteries column. The crystal has been reattached to the phyllite. It’s in excellent condition, with chips on the […]

A group of small specimens of columnar celestine, remarkable for their provenance. They are from the stratum in Blair Co., Pennsylvania which is the type locality for celestine. The town name usually given as the type locality is Bell’s Mill, Bellwood, and the labels for this specimen group say Tyrone, which is a few kilometres […]

This specimen features a singly-terminated 2.4 cm fluorapatite crystal together with an amphibole matrix, from a rare Pennsylvania locality for fluorapatite. The fluorapatite crystal is well-formed, with a glassy termination and nice deeper colour at the termination. Under shortwave ultraviolet light, it is golden yellow, and under medium wave ultraviolet light there is a thin […]

This is a great twinned rutile from a farm field near Quarryville in Lancaster Co., Pennsylvania. The fields in Lancaster Co. and adjoining Chester Co. are famous old (Dana) localities dating back to the early 19th century (with many specimens labeled “Parkesburg”, as the fields around Parkesburg produced fine crystals). The rutile crystals from this […]

This specimen is a section of a seam of radial aggregates of wavellite crystals. There was not enough room in this seam for open space for the radial aggregates to form free-standing balls with terminal faces (there are actually a few terminations in small gap areas if you look for them, but most of the […]

A great miniature with twinned K-feldspar crystals (adularia variety), delicate green amphibole crystals (byssolite variety) and small sharp elongated prismatic crystals of prehnite. Very nice crystals of all of these minerals! With magnification, one can see that some of the prehnite crystals are speared by/perched upon byssolite needles – extremely cool. There are tiny pyrite […]

This piece features twinned K-feldspar crystals (adularia variety), and wonderful delicate green amphibole crystals (byssolite variety). The byssolite crystals stand well up off the matrix. In excellent condition overall, a couple of missing adularia tips. The alpine pocket that produced these specimens was found in the 1960s, just as the quarry closed operations (it is […]

A group of calcite crystals from a rare locality – Conshohocken, Montgomery Co., Pennsylvania. These crystals are sharp and quite lustrous, with nice terminations – they are great. In excellent condition overall, a couple small peripheral crystal areas are incomplete and a couple of small nicks on the piece. This is a really nice calcite […]

Detailed Description A superb smoky quartz crystal from the Smoky Mountain find. This crystal is sharp and transparent, with absolutely brilliant lustre. Upon close inspection one can see beautiful growth patterns on the large triangular face. At the base are small, colourless parallel quartz crystals. In excellent condition – one tiny edge chip, not an […]
