Talk to John Pinkerton at B.C.Clarks, Penn Square. He's been there for years and now is the store manager. Knowledgeable, friendly, and honest. I've purchased from him and he knows the merchandise.
Rings Etc, off of Broadway in Edmond. Roger is the owner and is a long time family friend. He is a stand up guy, won't BS you and will stand by his work. He made my wife's engagement ring and then her wedding ring and band for us. I'm not sure how his prices compare, but he's a self-made craftsman and worth his price.
R&R Jewelry off of NW 51st and Western. Has been there for over 30 years Larry and his Son Steve do the work there, and Steve's a gun guy and will be adding a small gun store to the building. 405-848-2124.
