Update: Had these tested at my jeweler and they are indeed, CZs as she tested the stones with their diamond tester and did not show natural diamonds. Preloved --Bought these thinking they are Affinity Diamond earrings but they are definitely CZ, so I'm assuming they are QVC Diamonique CZ Earrings. About 3/4-1" in length. I tested these with my diamond tester and they don't register as well. can fool almost anyone, including my jeweler who, at her first glance at them thought could possibly be natural diamonds until she tested them. These are however, Solid 14k yellow gold Leverback earrings and are in proper working order. As IS- NO RETURNS! smoke perfume free home.
