I was wondering if anyone has some websites to recommend for buying a strand of 10mm white pearls. I'm looking to spend about $30-$50. So far, I've found some options at abeadstore.com, firemountaingems.com, priyaimportsinc.com, and youpearl.com. But I imagine there are some websites out there that I haven't yet hit.

 Thanks!
 

 10mm is pretty good size for pearls. 10mm nearly round good quality fresh water pearls easily run more than the 30 to 50  you hope to pay. You should be able to find very nice potato and irregular shape pearl as large as 10mm in that price range. I can suggest places like American Pearl (www.americanpearl.com) and Joseph S Strachura for better quality pearls.

Thanks for the links--I may indeed go with the more expensive options. 

 Another option would be Swarovski glass based pearls. They have a very good feel and look very nice. Swarovski imitation pearls and imitation "shell pearls" are much more affordable yet look and wear quite well if you really want larger round smooth pearls.
