Dolomite with Quartz (Fe and Mn bearing) (near Kutnohorite)

Dolomite with Quartz (Fe and Mn bearing) (near Kutnohorite)This piece was collected in 1974 by my grandfather, Dave Bergman, and was part of my fathers collection for over 20 years and then came to me. The piece features vitreous, tightly intergrown rhombs of soft orange pink iron and manganese bearing Dolomite (approaching Kutnohorite chemically) which are associated with a few sharp, lustrous, gemmy colorless Quartz crystals on matrix. Ive never seen a Dolomite quite like this from the Camp Bird Mine, and

A beautiful group of sharp

acicular spray of Zinkenite crystals

It is very difficult to find any samples of this mineral on the market today

Specimen # BROOK31905

Specimen# CO712B76

Specimen # BOL711B89

The piece is in excellent condition featuring a predominant 1 inch crystal at the top of the piece surrounded by smaller “blades” on matrix

and this particular piece was one that I held back when I first purchased these specimens in anticipation that more were on the way

This piece was collected by Patrick and Carl Auclair in the 1990s

This piece is one of the single largest twinned Cassiterites from Viloco that I’ve handled

It’s a great full-sized miniature to boot
