Flaunt your wealth and love for firearms on your finger:
Made by Swiss designer Johanna Dahm.
They look quite neat. I can’t see the comfort level being that high though considering the edges are quite thin and jagged looking.
The price is not listed, but since these are 10g bullion bars I can tell you that they alone go for ~$600. Add what the artist thinks her time is worth (which is usually ridiculously high) to that and you’ve got yourself quite an expensive piece of jewelry to show off.
