they use a tester, and so did my neighbor..

Jess put them under a scope, as well as the lady at Zales, who i almost sold them to, but she was acting shady as sh!t so i passed on it...

Jess has a GIA certification, GIA is a school, not an appraisal... you need to go to NAGL (North American Gemological Laboratory) in Bellevue to get them appraised...

im having a friend take them up there for me eventually...
