Strand No. 5 as numbered by Pearl Dreams looks like it has a interchangeable CliClasp Pearl, which means one should be able to purchase additional CliClasp in future, making the strand very versatile.
I have to say I have bought from Auction Pearls and they are gorgeous (peacock Tahitians). Great price too (would not have been able to afford such a nice strand from another shop). She sent me lots more photos when I asked for them and always returned my emails promptly. Why buy from ebay? Cost!
