A beauty in its own category, this stunning opal ring features an opalised shell fossil. This shell once lived on the edges of an inland sea in Central Australia. Over 100 million years the shell has become a solid opal in one of nature's true wondrous transformations. We simply polished the shell in its natural shape and set it in solid 18K gold, forever preserving its beauty. A beautiful unique ring suitable for everyday wear, that will sparkle and shine its amazing colours and lift your spirits with just a glance.
