Opal earrings in solid 14K gold.
October's birthstone. Opal's colour play comes from silica spheres diffracting light, so the flashes shift as you move. No two stones behave the same way.
Caring for opal. It is softer than most gems and holds water in its structure. Keep it away from heat and harsh cleaners, and take earrings off before swimming.
