you're getting a beautiful sterling silver gold vermeil pendant I thought there was diamonds in it so I hit it with my diamond tester it's just metal that looks like diamonds. but I did hit the stones they are not glass they are real gems I just don't know what because I don't have a gem tester period because usually the next question after you tell someone with a stone is is it natural or man-made and only a gemologist can tell you that period so they're real something I don't know what period if you have questions just ask think you have a great day boxA
