I love opals an had the opportunity to purchase one that was over six carats in weight. The photos that were taken were excellently done by a very good photographer. I received it yesterday, and am not so sure I like it in person. It has excellent play of color, but the opal seems to be a little more opaque in person than it seemed in the photos.
