If you had any knowledge you would know that gems are NOT flawed, but included, you bought a SI (slightly included) tanzanite, as stated on the auction you bid and won. Also, you are welcome return it within 7 days of receivng it for whatsoever reason ALSO stated on our auction. As you have not offered us the opportunity to refund you for a gem you bid on and received as advertised your rating is returned in kind. Responded 26 Mar 2008
