i have a half carat solitair diamond ring I got from Kijiji. In the appraisal it says the retail value is 6400 but the previous owner purchased it for 3400. Now I happen to visit a chain store in the mall which happens to have a diamond show. They were offering a free appraisal. If i wanted to do an upgrade, i can use the appraisal amount of my ring and buy another ring but should be worth double the stated appraisal amount. They told me mine is worth 3200. At first, I was thinking its not that bad. The price depreciated for just a few dollars from how much it was bought 10 yrs ago. But then i realized the previous owner actually purchased the ring for its actual price and he didnt actually saved any money. I dont understand what you mean by the appraisal value. Is this the actual value of the ring? Or the chain store just told me the ring cost 3200 so i can purchase a 6400 ring from them? I think somethings fishy is going on here. Will someone explain to me what it means by appraisal value? Thanks
