We don't know anybody, but you might consider contacting either Bill Lieberman or Richard Sherwood who are independent GIA Graduate Gemologists operating out of Florida, they are bound to know the better jewelers in the area and would also be able to tell you who to stay away from. You can find their information via the "appraisers" link at the top of this page... Gemologists can be a fabulous resource because they tend to know most of the jewelers in their respective area either personally or by reputation because they end up seeing a lot of their work.
