The "Circle of Life" has been a classic for several years. This one is perfect! Less than 3/4" in diameter, it is not too big or too small. The very small Diamond-Like Cubic Zirconia are prong set in Sterling Silver and bonded in Rhodium for a durable finish that won't tarnish. The chain is 16" in length with a 2" extender. Approximately the size of a nickle, 18mm in diameter x 1mm row of stones.
