Based on a specimen from Shigar Valley, Pakistan.

I’ve been going to mineral shows with my achtaragdite crystal model handbag for a while now, and it’s been a reliable conversation starter every time. (If you haven’t read about my crystal model handbag yet, you can do so here.) People really seem to love the idea of wearable crystal model art, and after a little while I thought maybe the world needed another example - perhaps a hat this time! I went through my collection looking for a crystal with the correct proportions and the right level of complexity, eventually settling on a perfectly transparent little topaz from Pakistan.
