Cobaltoan Calcite from Arhbar Mine, Arhbar, Morocco [db_pics/pics/jmix07-167c.jpg]

The size of these cobaltoan calcite crystals is just remarkable compared to the average specimen you see – these sharp scalenohedrons rise to 1.3 cm above the matrix! It is nearly pristine, with just a few vrey , very minor dings here or there. Pretty pink blush color with silky micro-stepped faces. A very rich specimen with unusually pastel color !

Calcite from Jalgaon, Maharashtra Province, India [db_pics/pics/jmix08-08d.jpg]

When I saw this amazing, glowing golden calcite, it was on a big, clunky matrix that detracted from the overall beauty. So we had it trimmed to create a matrix that was more appropriate as a setting for the jewel-like crystal. The calcite itself is BIG, measuring 5.5 cm across the top, 6 cm down, and 4.5 cm thick. And, it is absolutely pristine.

A LARGE cabinet specimen featuring translucent calcites to almost 4 inches, 9 cm in size, isolated in a matrix of coated quartz crystals. The crystals show good luster and very sharp form. The specimen is in fine shape, with just a couple of very unobtrusive contacts. Sawn on back to remove from the matrix. A big, showy and dramatic Russian specimen and very unusual in its association!

A rare example of beautifully crystallized, acicular uranophane from NEW MEXICO. At first glance, this looks like the Canadian material above. However, it is from a small and hard to get locality. Specimens are few, and I have seen only 3-4 for sale in the last decade

Another unique specimen from this famous pocket , with inesite in isolated crystals to 1 cm (unusual!) , mixed with small, sharp orange prehnites, perched atop a gemmy and lustrous calcite rhombohedron! I have not seen another like it.

This crystal is SHARP and so oddlooking I thought it was a barite at first. But it is a calcite, showing fascinating growth patterns. Cleaved only on the back, otherwise complete all around.
