History

These opals are opaque, pastel-pink gems. Although they don't exhibit the play of color found in precious opals, their lovely pastel pink shades are simply beautiful. If you look closely at these pink pretties, you'll notice they have swirls of billowing white throughout. The ghost-like inclusions give them a haunting beauty and their soft color adds compelling femininity. The result is a gemstone that will quickly capture your heart.

Care

Avoid steaming, chemicals, and ultrasonic cleaners. Use warm, sudsy water for cleaning and a gentle cloth for drying.
