Our opal inlay necklaces feature top quality opal from Australia inlaid in 14k gold. Some of our Australian opal necklace designs have opal accented by diamonds or other colorful gemstones. Most of our necklaces are shown in yellow gold but any of the necklace designs you see can be made in white gold or platinum by special order. If you don't see exactly the opal color or necklace style you are looking for, contact us about creating a custom opal necklace just for you.
