Just wanted to share this find. Premier Designs has a matching starfish ring and necklace. I haven't seen them in person, only came across them in the recent catalog. The description says:
Rhodium plated cubic zirconias. Ring is item # 1603 ($48). Necklace is 16" with a 2" extender, item # 20101 ($54)
I love Premier jewelry and wish these were around when I got married. I love it that the ring is fairly petite as so many out there are too large for my taste.
If you don't already know a Premier rep, you can look one up on their website. Sometimes I can find their stuff on ebay, too.
