After giving my wife a handmade plastic faux-diamond engagement ring, I decided I’d better get serious and come up with more permanent wedding rings. The polycarbonate ring was funny, but even made out of an engineering plastic, there was no way it would last.

We scoured the vintage jewelry shops, and then the dreaded mall stores, until we finally decided that the only way to get exactly what we wanted was to design the rings ourselves. And like any self-respecting industrial designer, I’m prone to believing that I can design and make anything.

Luckily for me, the making part turned out to be easy — I simply sent my CAD design to a 3D wax printing house, then sent the wax prints to a jewelry foundry and got back platinum rings.
