Does the ring look like it's made of both silver & gold?. Please show a picture of the outside of the ring. Could just mean Silver Plate & 14K gold? or SD, SP for a maker, just can't tell from what I see
Here's a full pic of the ring. It's white and yellow gold. Pretty sure it's not plated because of the way it cleaned up, though I haven't tested it yet so I can't be sure (I hope not, though!).
