This is an excellent seller. The item was as it was described. I have tested the diamond with my tester and it was areal diamond. I have a diamond tester and a moissanite tester, the diamond tester has sound but the moissanite tester hasn't so the stone is areal diamond. Thank you very much and I will surely buy from you again as long as you sell real stones. The stone have come with a certificate of authenticity so I can sell it on my jewelle creations and my clients may be happy.
