What kind of metal does Aurate use for my engagement ring?Updated a year ago

We ethically source, sustainably make, and only use real platinum,  solid 18-karat, and 14-karat gold in our engagement jewelry. Measured in 24ths, 18-karats denotes 18/24 parts of gold while 14-karats denotes 14/24 parts of pure gold. Platinum is 95/100 parts pure. The remaining percentage is an alloy added to enhance durability of naturally soft metals allowing us to guarantee our products for life.
