Placed at the center of the opal ring, it reveals all its natural charm, to the delight of women seeking a mesmerizing jewel.\u003c\/p\u003e\n\u003cp\u003e Elegant and sophisticated, the opal ring is further adorned with precious metals and irresistible gems, such as the white diamonds that often surround the central opal stone in daisy rings.

Precious opals, like this one, display play-of-color due to the light. They are composed of tiny, aligned siliceous spheres of the same diameter. When light hits the stone, and depending on the angle from which it is viewed, a play of light dances across the opal's surface. Common opals, on the other hand, do not display play-of-color; their spheres are disordered and of varying diameters. Light simply gives them a \"milky\" appearance.\u003c\/p\u003e\n\n \u003cp\u003eIn the collective imagination, opal was believed to have the power to render one invisible.
