We love this created opal jewelry. It is more resilient and stronger than natural opal. It’s fire is more consistent. It allows artists to inlay the stones in beautiful ways like these sea turtle earrings with sterling silver. We find it to be a great addition to our collection of natural opals because it can be worn everyday with out the fear and worry that it may crack. Though it is made in a lab, the elements they use to make the opal are the same elements that are found in natural opal, silica mixed with a small amount of resin. We also have starfish, crabs, jellyfish, flip flops and more.
