Fonderie 47, a social venture started by Peter Thum, creates jewellery from AK47 assault rifles that have been confiscated from African war zones. The purchase of each piece helps fund the destruction of a certain number of illicit weapons. It is a symbolically powerful project that not only has raised awareness about the issue of illegal weapons in Africa but actually helps destroy the guns themselves. And the jewellery—crafted from AK47 steel, sustainably sourced 18k rose gold, platinum, and conflict-free diamonds—is beautiful.
