A beautiful specimen featuring a ball-like aggregate of prehnite crystals on the right and many smaller fan shaped crystal groups including one prominent one to the left of centre. The prehnite crystals are a delicate light green colour, sharp and lustrous. In excellent condition, a couple of small incomplete crystals low on the piece and […]

This is a superb piece, with a ball on the left-hand side and a beautiful main upright fan on the right. The prehnite crystals are sharp, with bright lustre and nice light green colour. There are a few small quartz crystals in association. In excellent condition, no damage. Stands perfectly for display as photographed. A […]

This large cabinet specimen is comprised almost entirely of intergrown fans of light green prehnite crystals. The crystals are beautiful, sharp, and lustrous wih a very delicate colour. The largest fans are thick and wheel-like, while some of the small ones ar very slender. It had been lifted off the matrix and is therefore hollow […]

An impressive large cabinet specimen featuring two main balls of radiating prehnite crystals and a few quartz crystals in association. The prehnite crystals are light green, sharp and lustrous. In excellent condition, no damage, some minor incomplete crystals around the outer periphery of the smaller clustered crystals at left (first photo)/lower (last photo) where it […]

Beautiful, sharp, stacked calcite crystals with excellent lustre from Chenzhou. The key feature of these calcites is that they are in fact comprised of two generations of calcite – there is an internal core of a single white scalenohedral crystal, and it is overgrown by flattened calcite crystals. The flattened crystals have highly lustrous small […]

This miniature features a large tennantite crystal (confirmed by analysis), measuring 2.5 cm. There are a number of smaller tennantite crystals intergrown with the large one, and the tennantites are also accompanied by chalcopyrite crystals and minor siderite crystals. The lustre on the tennantites is brilliant, however they are not single crystal faces – the […]

This specimen from Kaiwu is really distinctive (and really hard to photograph). It is comprised almost entirely of bright sharp chalcopyrite crystals, the largest of which is 3.5 cm. Some of the chalcopyrites are quite complex in growth. I’m really not one to lie around and attribute shapes to clouds – or minerals – but […]

Sharp, bright chalcopyrite crystals with groups of small intergrown tennantite crystals and delicate siderite blades from Kaiwu. The tennantite (I’ve had it analyzed to confirm) crystals are slightly silky looking but with magnification the crystal “surfaces” are comprised of a myriad of very bright parallel crystal faces. The chalcopyrite crystals are nicely balanced, with some […]

Crystals of chalcopyrite, perched and in among siderite crystals, and topped with dolomite crystals dotted across the piece. The crystals of all three minerals are sharp. The chalcopyrite crystals are bright and lustrous – and there is a lot of chalcopyrite on this one. There is a bit of edge wear and some minor chipping […]

This piece features a multitude of intergrown and chalcopyrite crystals perched on and in between bladed siderite crystals. The chalcopyrites are sharp and bright. There are small quartz crystals in with the chalcopyrites, including a cute doubly-terminated one (1.3 cm). No damage to the display side, just points of attachment at the bottom and periphery. […]

Aesthetic groups of chalcopyrite crystals with clusters of delicate siderite crystals from Kaiwu. The chalcopyrite crystals are sharp, and lustrous. The siderites are all over this one and provide a lot of texture. The chalcopyrite group at the top is super – sharp, well defined, with simple mirror-bright faces, intergrown crystals. Virtually no damage – […]
