Made of metallic stainless steel (hypoallergenic and colorfast). The opal cut into an oval in the center beautifully displays "play-of-color," changing colors like a rainbow—red, green, and blue—depending on the light, emitting an exquisite shine. To complement this opal, tiny diamond-like stones are arranged in a halo around it, adding an elegant accent. The ring band is made of sturdy steel with a substantial thickness, and delicate decorations are applied to the sides to reflect light. This band, which combines robustness and delicacy, powerfully supports the fantastical beauty of the opal. The background is subtly blurred, creating a composition that highlights the mysterious brilliance of the opal and the sharp texture of the steel, resulting in a very impressive ring that harmonizes strength and elegance.
