The leverback finding in fine jewelry is fabricated in the same metal as the earring it carries, which matters for two reasons: it eliminates base metal contact at the piercing, and it ensures metal continuity throughout the piece.
Stone Story
Pigeon's blood ruby presents a vivid red that reads pure in hue, with a slight blue component that deepens the red without shifting it toward purple. Strong chromium fluorescence adds luminosity under daylight, making the stone appear to generate its own light. The combination of saturation, hue purity, and fluorescence is what makes the designation the benchmark for fine ruby color.
