My family has been using Plaza Fine Jewelry (http://www.plazafinejewelry.com/) in the Plaza of the Americas in downtown Dallas for 30 years. When I went to buy my wife's engagement/wedding ring last year, I gave him my price range and he actually stayed within it rather than trying to tempt me with something a little more. Abe is the owner and his wife is usually runnng the front. Just tell them that Jerrett Jan sent you.
