Blinga ring ring

now when this was bought it was supposed to have been white gold with diamond chips. I think the gentleman in question was full of BS as there is not a single marking on it from what I can see. I had teeny tiny fingers back then and if my ring sizer thingy is correct this is 4 1/2 no bigger than 5. it has not tarnished since sitting in it's box for over 10 years so it's not silver. I will put the new price he told me but again that's probably BS TOO. I must stress this is a VERY SMALL RING so allow the size to be as small as a 4 . just in case my budget sizer is off.
