A really different specimen for Mundo Nuevo, this is a cluster of sharp, lustrous pyrite crystals. These pyrites have a striking, colourful iridescence that makes the piece! In excellent condition – no damage. The pyrite crystals are incomplete around the back, but they are recrystallized, indicating that this group separated from the surrounding host rock […]

Detailed Description This is such a cool specimen – a brilliantly-lustrous pyrite crystal hosts a couple of little “forests” of tennantite crystals. It seems the tennantite crystals chose to grow on the cube faces of the pyrite. The pyrite is incomplete and there is minor chipping visible upon close examination of the tennantites, but this […]

Detailed Description This is an aesthetic arrangement of sparkling bright green dioptase crystals on light matrix. The dioptase crystals are sharp and lustrous, with good internal play of light.  In excellent condition, no damage, and sits perfectly as photographed. Very pretty! About These Dioptase Specimens Dioptase was first described from Altyn Tyube, the type locality […]

Detailed Description Pure, intense dioptase green, this is a gorgeous miniature. The dioptase crystals are sharp, lustrous and have nice internal play of light. This specimen has particularly good, aesthetic form. In excellent condition – no damage visible from the optimal viewing angle, a couple of missing crystals around the back.  Lots of sparkling green […]

Detailed Description I love this one – it is a gorgeous, perfect barite. This piece features a dominant group of glassy, honey-yellow crystals – they are so clear that you can see other crystals in the group straight through them. This cluster is comprised of completely pristine crystals. The group measures 3.9 x 3.2 cm. […]

Detailed Description A beautiful barite from Cerro Huarihuyn, this specimen features a group of clear, glassy, honey-yellow crystals rising up off the matrix at an aesthetic angle. The barites are highly lustrous, and also so clear that you can see other crystals in the group straight through them. Virtually pristine – a couple of rubs […]

Detailed Description This one is a little different – it is water-clear, with a very slightly smoky colour tinge to it. The central and lower portions of the crystal are attached to the matrix, and around the top edge of the crystal the transparency is such that you could read through these areas of the […]

Detailed Description Beautiful clear, glassy, honey-yellow crystals of barite from Cerro Huarihuyn. The central barite crystals on the piece are in parallel growth, and measure 2.8 cm. These barites are highly lustrous.  Virtually pristine – one small rub to the back of the main group, not at all distracting (particularly from the front). The third […]

A vug lined with calcite crystals hosts a beautiful deep green dioptase. The dioptase crystal measures 1.7 cm in length – it is sharp and brilliantly lustrous, and it has a nice internal play of light, to help show off its amazing colour.  There are a couple of parallel growth crystals around back and side […]

This cabinet specimen hosts several sharp crystals of dioptase. The large one is quite the size, measuring 1.7 x 1.1 cm.  Excellent separation of the crystals and great contrast with the hosting calcite. One rub on the large crystal visible with magnification, and one small nick around its right-hand side – neither is distracting. The […]

This aesthetics of this one are great! There is a series of calcite-lined openings containing the dioptase crystals, and the overall effect is as if this is a cascading river of sparkling green crystals. The dioptase crystals are sharp with brilliant glassy lustre, and they have excellent translucency and internal glow under the lights. The […]

These deep red vanadinite crystals from Morocco are perched on delicate bladed crystals of cream-coloured barite. The largest vanadinite is 1.0 cm across. In excellent condition, this is a first class specimen. If you’d like to see more about the Mibladen Mining District, including photos of some of the vanadinite workings, see Morocco: The Northern […]
