The details
Shifting, milky color rolls across the round lab-created opal in these stud earrings, set in bright sterling silver for a look that stays quiet and polished. The stones are smooth cabochons, treated by impregnation, and they catch light softly rather than flashing. The sterling silver carries a polished, rhodium-plated finish that gives a crisp, bright shine. Each button style earring sits close to the lobe and fastens with a post and push back. You can wear them with a white tee and jeans, or with a tailored blazer for the office. A thoughtful pick for anyone with an October birthday.

Jewelry care
- Sterling silver darkens naturally with air; the rhodium finish slows this down. A silver polishing cloth brings the shine back, and an airtight pouch keeps it there.
- Opal is softer and more porous than most stones: wipe it with a soft, damp cloth and never soak it or use an ultrasonic cleaner.
- Put jewelry on last, after lotion and perfume, and take it off before showering, swimming or sleeping.
- Store each piece on its own in a soft pouch so it doesn't scratch.
