I won this gorgeous gemstone along with many others in one of those storage locker auctions! I am not a gemstone expert so I took them to a pawn shop and paid to have about 100 of them tested, it was really expensive! The ones I tested turned out to match their certificates. Almost ALL of the Rubies I list have been tested on a Precidium II I am posting all of my gems at less than wholesale prices. After paying to get them tested I was told that I should have them graded and THEN get them appraised and THEN I would have to find a buyer to pay a ton for them. It all seems so exhausting . . . not to mention expensive! I realized that I will never get around to selling them because of all the steps. They've been in a locked closet for over ten YEARS. So I thought that I would just sell them for about what it costs to get tested by a professional and taking into consideration the size and cut of each gem. I don't have an expensive gem tester at home BUT my diamond tester can show the hardness of a stone (the MOHs scale) and can also tell if a stone is glass or CZ. This gem is testing at about 6 MOHs which is good *Tanzanite* hardness which is around 6.5 -7 mohs This is one of those perfect gemstones from the color that just jumps out at you to the excellent cut and the size! What a stunner!
