DW and I have a jeweler in St. Thomas that we have been doing business with for about 10 years now. She is very good. Kuki is right, do your homework before you leave then when you get to the islands you have a good idea of what a good price is. For us we found that we would much rather have quality over quantity. For example, you could buy 2 karats of some very good diamonds instead of 5 or 6 karats of some so-so diamonds. Any jeweler can give you a chart of how diamonds are rated. Everything we have bought has appraised for double or triple what we paid.
