If you're looking for baroques I highly recommend Pearl Paradise (the only legit PP around here). Jeremy's got some fantastic baroque freshwaters that are humongous (I find anything less than 10 mm small after those) which have excellent luster and form, and he's also got a new line of Tahitian baroques. With pearls, the grading criteria are similar regardless of type, size, shape, surface, luster, color - freshwaters are slightly different in terms of shape but if you're going baroque all bets are off. It's personal preference, really. PP's monthly special is a very good deal. I got a similar bracelet off Care Ehret (lovely pearls) with gold spacers and rolled gold clasp for almost double (not complaining, just saying how big the price difference is). There's a new line of Tahitian bracelets made from pearls from Josh of Kamoka pearl farm. I highly recommend it - it's unique and the pearls are farmed ecologically.
If you like smaller baroques, Cathy Cardellini has also got some and she lives in Australia too.
www.catherinecardellinipearls.com - correct me if the website is wrong. Some of her new biwa and baroques are to die for. I got my favorite pink rice pearls off her.
For the really exotic go for Sea of Cortez (really can't afford these quite yet). Care Ehret does have a lot of these beauties and she tends to use high carat gold in her pieces as well. I love some of her more unique clasps. She sells on ebay under Druzy Design, and she does mostly baroques. I still prefer the more classic round strands for GSS and WSS, but she's got some interesting keshis as well.
