"We ordered my engagement ring from since1910.com, and I am so impressed with it. The workmanship & quality far exceed what we saw at chain jewelers when we were first looking around. The price was unbeatable & being able to choose my own diamond was a huge plus. When I started contact with them, Christina got back to me the same day. I would absolutely recommend this jeweler & we will buy our wedding bands from here."
