I ordered. Pair of 4 carat diamond stud earrings from them & when they arrived, I compared them to a couple pairs of CZ. Earring studs that I have & the supposably diamonds had no more fire, color or clarity than he CZs. Then I took them to Costco's to compare them to some diamond studs of the same weight that I had seen there & there was no comparison, the Costco diamonds had a better color & clarity rating, & were 100 times brighter & shiner than the pitiful diamonds from Super Jeweler. So I packed up the studs that I had ordered & returned them by Fed Ex, & insured them for $10,000. I hope I get a refund, assuming that I will, I will go to Costco to buy my studs. There I know that I will get what I pay for, fair & square!
