I made it out of 16 oz roofing copper, and applied a patina to the entire box, in which the lid turned out very strangely; which I love.
An art deco pearl ring from 1925 was intended to go inside of it, but I ended up losing it by a penny on eBay, and I could not find a suitable replacement, so I just decided to give her the box as is.



There are a few more photos here.
