Regular plain rings are slowly going out of date. The rings that are unusual, are the ones right now that are in. Tiger rings, flower rings, onyx rings.... just what ever floats your boat I guess ;) but I really adore the cougar selection of rings.
Above is a ring that Rachel Zoe wears most of time and I just love it. It's in style and it's bulky; so if your wearing something simple, it stands out. It's a main necessity to own at least one stylish bulky ring.
