Item Description

The St Andreasberg Area in Lower Saxony is famous for producing some iconic German mineral specimens, including some really attractive Calcites. This toenail sized specimen is a beautiful crystallized "spray" featuring many sharp, well-formed, prismatic, gemmy, white / colorless, trigonal crystals measuring up to 1.2 cm long with no matrix. The piece is glued to an old cork, and I didn't want to remove it to main its historic pedigree. Please note, the specimen itself measures 3.2 x 2.4 x 2.2 cm, and this does not include the cork. A very attractive old time specimen of this beautiful classic material. Ex Kay Robertson Collection (#5657). Kay was a prominent California collector, who specialized in European classics. She nearly lived 100 years from April 1920 - March 2020. See the article in the March-April, 2007 Mineralogical Record ( https://www.mineralogicalrecord.com/pdfs/Kay%20Robertson%20Collection.pdf ), and the 50+ page article in the German Magazine "Mineralien Welt" November-December 2017.
