I purchased 4 gemstones from an auction house that I have never seen before. After some research online, I “think” it might be Tanzanite but would be grateful if someone could tell me for sure. The gems appear mostly blue but when you look at them from another angle they appear as having alot of purple and yellow/green colors to them. I have attached an image of the stones.
If, my suspicion is correct and they are Tanzanite, what price range would they go for retail? The larger oval is 6.63 carats, the second oval is 2.80 carats and the other two are 2-4 carats each. I saw some similar stones online that were about 5-7 carats each and sold for $6,000.00 but on the other end I had one person tell me they were not worth much Hmmm!!
Any information would be a huge help to me at this point! Thanks.
