For those that aren't aware of it, synthetic Opal is actually preferred to natural opal for jewelry items. Natural Opal is not particularly well-suited to being used in jewelry since it's a relatively soft gemstone, breaks easily and has to be protected from sunlight and many chemicals. Please note that the clutch or butterfly back design may vary depending on available supplies.
