White gold and platinum have been the default sapphire setting metals in modern fine jewelry for their color contrast, but yellow gold makes a distinct case for medium-toned stones, contributing warmth and a vintage character.
A Notable Quality
Two things work in favor of 14kt white gold for everyday wear: the hardness the alloy contributes and the protective surface the rhodium plating adds. Together they make it a more resilient daily metal than its refined appearance might suggest.
Stone Story
Diamond's refractive index of 2.417 is one of the highest of any transparent mineral, and it's the optical property that determines how light bends and reflects inside the stone. Combined with diamond's dispersion, these two values produce the brilliance and spectral fire that no other gemstone replicates at the same intensity.
