Description

I saw and had really plenty of them - but this stands out the crowd; the assemble is simply amazing. But first more about the discovery: this material is often wrong labeled as "agate" or "chalcedony", both is wrong! This material was analyzed and it is amethyste - spheres consisting of micro-crystals. This particular specimen is developed as floater - a first generation of light, tiny spheres fored a bowl - in the center of it larger, darker spheres fored an exposed group, which is finally partly covered with elongated tiny crystals of thrid generation. An absolutely out-standing piece! Although there was relatively much material - now the locality doesn´t produce new stuff, most good pieces are absorbed by the market and the particular specimen is for sure a mayor-piece in finest quality. No significant damages to report.
