On most 18kt white gold jewelry, the surface is actually rhodium, a platinum-group metal applied over the alloy that produces a brighter, harder, more reflective finish than the gold beneath.
Stone Story
Chromium impurities within corundum absorb certain wavelengths of light and transmit red, producing ruby's characteristic color. The same element in beryl transmits green, producing emerald. Fine ruby's color is the direct sensory result of that trace element's interaction with the host crystal.
