The details
A 14K white gold oval pendant set with a natural opal measuring 6 x 4mm and weighing 0.55 ct, held in a prong setting with a rhodium-plated finish.
Opal has been recognized as the traditional October birthstone for generations, prized for its unique play-of-color, or "phenomena," in which flashes of light shift across the stone as it moves. Many cultures have historically associated opal with hope, purity, and creativity, and birthstone jewelry has long served as a personal way to mark one's month of birth.

Jewelry care
- Solid gold won't tarnish. Warm water with a drop of mild soap and a soft brush keep it bright.
- 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.
