Description

Superb crystal of twinned chalcoryrite, a quality that is the best for the species!The crystal has everything at highest level, color, luster, form and it's even a realatively large crystal for the quality! Yes, the color is better than others, with intense matallic yellow tone!The crystals have several faces and all are super shiny!The crystals are placed on a matrix of shiny black sphalerite, quartz and calcite, offering a great contrast! The quality of the species on the matrix is very high, as well, only the crystals are small!That's a fantastic, pristine miniature! This quality will not keep being produced for ever, so get one when you can!
