Cathy, that's a pistachio Tahitian in squidlet's head, about 12mm, and he's hanging on a cord I picked up at a little shop in Barcelona - a very fine coating of metal thread over a flexible interior...Very versatile, as it goes perfectly with bronze, rose gold, etc. Havent run across one like it elsewhere...
Ckrickett, the earrings look great on you - I knew they would!!!
Urchin, your puffy ring is gorgeous, and hanadama, those Tahitian drops are exquisite - perfect setting for that size/shape!
Lovely to start the day with a big dose of beauty...
