The details
Playful and a little free-spirited, this dolphin pendant brings a Bohemian sensibility to a polished sterling silver form. Two lab-created blue opals add a shifting, watery color that seems to move as the light does, giving the small silhouette real presence.
A bright rhodium finish gives the surface a cool, silver-toned shine, while the polished silver stays smooth and clean in its lines. It hangs from a chain of your choice, so it can be worn quietly on its own or layered with other favorites for a more relaxed, personal look.

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.
