Thank you Lorenzo. I have found looking at your recent posts showing these unmounted gems very interesting. How lucky you are to be able to see these in person. I am thankful that the Museum has decided to exhibit more of these gems.
Thank you so much for sharing them with us. I, for one, would not know about these gems except for your posts.
I am intrigued as to why so many beautiful gemstones were not mounted in jewels - but I suspect there is no simple explanation.
