Lab created opal jewelry offers the same silica structure and color play as natural opals, grown under controlled conditions rather than mined from the earth. These stones display the signature flash and fire opal lovers seek, with more consistent patterns and fewer inclusions. Each piece in this collection features lab created opals set in .925 sterling silver. With free US shipping and a selection built over nearly two decades, finding your next opal ring, pendant, or earrings takes minutes.

Both contain hydrated silica and display similar optical properties. Lab created opals grow in controlled settings over months rather than forming underground over millions of years. This results in more consistent color patterns and fewer natural inclusions.
Lab created opals measure 5.5 to 6.5 on the Mohs hardness scale. They work well in earrings and pendants. Rings require more care since hands contact surfaces throughout the day. Remove opal rings before heavy manual work.
Use a soft cloth dampened with water. Avoid ultrasonic cleaners, harsh chemicals, and prolonged heat exposure. Store opal pieces separately to prevent scratching from harder stones.
