Frequently asked questions
-
Is opal durable enough for jewelry?
Yes, with appropriate care. Opal scores 5.5 to 6.5 on the Mohs hardness scale, similar to glass. Earrings and necklaces are ideal for daily wear. For rings, bezel settings offer extra protection. Remove before showering, swimming, and heavy activity.
-
Why does opal change color?
Opal's play-of-color comes from microscopic silica spheres inside the stone that diffract light into rainbow flashes. The colors shift as the stone moves in relation to light. No two opals ever display the same pattern, making every stone truly one of a kind.
-
Does opal look better in gold or silver?
Both work beautifully. 14K yellow gold adds warmth that highlights opal's warmer flashes (reds, oranges, pinks). Sterling silver creates a cool backdrop that emphasizes blues and greens. Rose gold offers a romantic contrast. All options are available at Erin Gallagher Jewelry.
