wifes got a ring given to her by nan about 15 years ago, we found it and a couple others shes been given over the years in her old jewelry box in loft.

not wanting to sell or anything just we looked at it and theres 3 sizable stones, each one is a fair bit bigger than the half carat solitare i bought her anyway lol

dont want the embarisment of taking to a shop to ask, in all fairness dont think would make a difference to her if there were just glass, its just one of those things you keep if you know what i mean, her nans quite well off but its a very old looking ring, just wondered if there was a easy test?
