Detailed Description This twin features a particularly fine “cross”, emphasized by prominent striations (the iron-cross pattern is exhibited on all sides of the specimen, but this particular cross stands out). In very good condition, one small contact and the goethite veneer is a little uneven in a couple of places (not display sides). Looks great […]

Detailed Description This twin balances very three-dimensional penetrating dodecahedra and prominent striations that emphasize the “crosses”.  In excellent condition, a textbook pyrite iron-cross twin. NB about the photographs: All of the specimens from this find are black-to-dark brown in colour. The lustre varies somewhat. In order to capture the crystal forms in the photos,  reflectors […]

An incredibly rare specimen of native gold in quartz and magnetite from Maryland. This specimen was collected by Fred Parker in about 1990. It was a small pile of rock that was apparently a minor iron prospect. Fred wrote to John in correspondence that he exhausted the site and that is was reclaimed for the […]

This is a fascinating specimen, so much so that it inspired John White to write the article “Disjoined Crystals” in  Rocks & Minerals, Vol. 93:3 May/June 2018, pp. 274-275. He refers to this dravite as “by far the classiest example [of disjoined crystals] that I believe I have ever seen.” A disjoined crystal is a […]

This piece features fanned aggregates of black tourmaline crystals frozen in quartz. Upon close examination, one can see that a small number of crystals are disjoined – this is the phenomenon John described in his “Disjoined Crystals” article in Rocks & Minerals 93:3, May-June 2018, pp.274-75, where crystals contained in rock that has been subjected […]

This piece features a well-formed dodecahedral almandine crystal in chlorite schist. It has good lustre and a dark red (warmish-red) colour. In excellent condition, minor edge imperfections. A fine Maryland garnet specimen from the John S. White collection (catalogue # 4.5.2). About John S. White  

A 2.7 cm garnet crystal in chlorite schist from Northern Baltimore Co., Maryland. This is a sizeable crystal from an unusual locality.
