33. Silver.
I don't wear jewelry (except the ring).
No way in hell I go with white gold. It's basically gold and silver mixed, then plated with rhodium. When rhodium wears off, you have to replate or it looks like shit. No thanks. I'm not about to pay gold prices for a ring that looks like a whole other precious metal.
I'd considered yellow gold, but yeah, I'd want purer--thus more expensive. I got silver, no regrets.
