Hi.. I was given a ring... I think it is a diamond white gold ring... the marking inside are dia 10,gtd, ga 375 and a marking which looks like a pair of glasses, there is also a square with what I think are 3 small dots... can any one help please

I think it may be silver because I found rings with gtd on silver but no white gold.

A marking which looks like a pair of glasses there is also a square with what I think are 3 small dots that would be the hallmark of who made it.

The dia 10 may be as .10 cents that called the diamond size in carat. The square and 3 dots resembles the hall mark symbol. Check with a jeweller, whether it is a white gold or a platinum. If it is a platinum u got a valuable GIFT.
