I was referred to Edwin Novel's site by a close coworker of mine because she overheard I wanted to buy a new pair of earrings for myself. I went online and purchased these gorgeous radiant cut diamond studs. When they arrived, I automatically tried them on and fell in love. However, I realized that the push-back backings were making my ear lobes a bit irritated. I called in & an agent answered immediately. I explained to her my concern and she was very empathetic to my situation. She guided me on how to do an exchange and upgrade to get push-lock backings (for a fee, but totally worth it) instead. I sent in my studs back and I was notified they had received them and were processing my order. The time frame was incredibly quick and in no time, I received my earrings back! They were much more comfortable than the originals and I couldn't be happier!!!!!!
