I have purchased a number of very nice things from Gem Shopping Network. They do bring in different outside vendors -- some are better than others. I have found they they offer some very nice and unique and rare items. They do provide a lot of detail on each item (size, gram weight, etc.) and I look closely at that when making a decision. I agree that the shipping costs are VERY high (depends on cost of the item) and if you decide to return, the return shipping cost with insurance really adds up. If you want to return, you do have to call to get a return authorization # -- not a problem, but something you must do prior to returning.
