Didn’t have to worry
I was recommended to the site by a co worker. I got this set and chose a .65ct H SI1 oval and the whole thing took 10 minutes. The rings arrived in less than a week. I really trusted my friends recommendation, but I had a friend who works in a lab with a microscope, check it out under high magnification. He is going to get his engagement ring here too. I am very satisfied, because I got a great deal.
