A White South Sea Pearl Ring is a unique piece of jewelry that combines the elegance of a pearl with the artistic design of a bird. Here are some features that might characterize such a ring:

Design Features:

1. Bird Motif: The ring features a bird, which might be delicately perched on the band or appear as if in flight. The bird could be sculpted in metal (such as gold, silver, or platinum) and may have intricate detailing like feathers, wings, and beak.

2. Pearl Accent: A lustrous pearl is often the centerpiece of the ring. The pearl could be placed in the bird's beak, held by its claws, or nestled into the design, symbolizing an egg or a precious object being protected by the bird.
