How much would this ring be worth?It has no marks on the setting but im almost positive the diamond is real.?

recieved one ofgrandmothers engagment rings.The setting is silver colored,strong,with no markings.has place for two very small spots where i was told there were also diamonds and the big one in the middle.I did the at home test for the diamond and think its real, under a magnifying glass the angles are very sharp,i cannot see thru it,it is unscratched on top and very faint yellow tinge.Does anyone have an idea what it might be worth as is?how long have bands been labeled? the ring was soposed to have been bought in early 50's.any help please?do jewlers usualy give honest answers?How much would this ring be worth?It has no marks on the setting but im almost positive the diamond is real.?The best thing to do is take it to a jeweler. They have special equipment to look very closely at the ring. Also, get a second opinion if you want to be certain their appraisal is accurate.How much would this ring be worth?It has no marks on the setting but im almost positive the diamond is real.?Yeah, go to the jeweler.They know everything.It'll be hard to judge just from the outside.
