The best bargain on a ship could be Loose Gem Stones. Although not all ships offer this sale in a weeks cruise. If yours does, you can have it set at Kay's on St. Martin in an hour. Kay's prices are fair, too. Personally, I find prices better on St. Martin but I still do my fair share of jewelry shopping at Havensight Mall at the pier in St. Thomas. Feel free to email me for the names of my most frequented stores.
