I'm a big believer in the concept - they let guys enjoy pearls while still looking masculine. I have bought several at this point - A 12 mm AAA Tahitian, 12 mm AAA South Sea, 13mm Fresh Water AAA, all from Pearl Paradise. What impressed me was being able to pick out the pearl I wanted. They are super easy to wear and look great. Here's the link

After seeing the link to TahitiMana, I like the hemp look as well - maybe that's next...
