Finding the perfect opal ring requires considering several factors, including the quality of the opal stone, its pattern, color, shape, and clarity. A high quality opal ring will have a bold, bright pattern visible when light hits the stone. The dome shape of the opal provides more luster than a flat cut. Small particles can ruin the aesthetics if the clarity is poor. The perfect setting depends on offsetting the metal band against the opal color to draw attention to the stone. Discovering the perfect opal ring takes perseverance and knowledge in selecting a high quality stone.
