Opal, 6.75 CT

“Look deep into nature, and then you will understand everything better,” said Albert Einstein. Looking into this natural 6.75-carat boulder opal, which preserves a small amount of the host rock as backing, and you can surely ascertain the power, the beauty and the mystery inherent in our world. Its awesome play-of-color, realized in a brilliant harlequin or mosaic pattern against a dark background, is nothing short of astonishing. This boulder opal is truly one of Mother Nature’s gifts, waiting for the gem lover to cherish.
