cranan,
So far you've been given a lot of good options in purchasing a piece of fine jewelry, and for each one you've gotten there are probably 10-15 stores not mentioned so let me add to the commentary and perhaps the confusion. There are more jewelry stores than beaches on this island just for starters.
Most of the better known and more widely used stores will have Stateside affiliates who will handle service for them.
Most if not all of the stores will offer the chilled beer, wine or champagne - depending on the size of the potential sale - or libation of your choice.
Most of the better shops will keep good records and allow trade-ins and trade-ups on potential sales.
The prices displayed on the items in question are NOT the prices you should be paying and this is where doing your homework before buying comes in. Have a good idea of what you want to purchase and what the price at home might be. Learn about the Cs of diamond buying.
Most diamonds purchased on the island will appraise much higher at home, generally 2-3 times or more, but know what those appraisals stand for.
This is just a quick guide to island buying and includes only the very basics but the bottom line for any jewelry purchase, IMHO, should be that the buyer know about what he's dealing in and purchase from an informed position.
The bottom line, in the end, has to be if you're happy with the item and the deal, and if you aren't, that's a good time to walk away and rethink or get prices elsewhere to compare. <img src="http://www.traveltalkonline.com/forums/images/graemlins/handshake.gif" alt="" /> <img src="http://www.traveltalkonline.com/forums/images/graemlins/handshake.gif" alt="" />
