This one of a kind boat has amazing stones! The flag and hull are boulder opals and the center sail is an intense ammolite with red, green, orange and yellow constant flash and no dull spots. Whenever I wear this piece at a show, people can't help but stare! The bezels are 22k gold and the under bezels are sterling silver. It is more than a pretty neck piece, it is a statement about lifestyle. Currently strung with gold, color enhanced, fresh water, cultured side drilled round pearls. It is strung with a 14k lobster claw clasp to about 17 inches in length on a durable synthetic fiber that moves like silk but doesn't stretch, shred or fray like silk.
