Consider using a stone mosaic medallion. It would add a nice contrasting element both color wise and texture wise. Compass and starburst patterns are very popular. If you would like to easily finish it off using a wooden t-molding be sure to choose a square or diamond shaped medallion rather than a round one. Medallions can be purchased at many tile distributers as well as online auctions sites.
