Sure looks like a Warwick and jewel count is correct. My vote is Warwick. Good match to the advert and a very nice pick up. Would probably look even more spectacular with the expansion band.
I'd prefer an earlier rice bead link with locking clasp. "Stonewall USA" made one of the best 1/20 10k GF rice beads I've ever worn but JB is right up there too. Anyway, it's going to be sold in the next few days .
Warwick from me.
