This lovely sapphire is set in 18KP white gold palladium. This alloy gives the gold a less shiny appearance than regular white gold and brings out the detail in the metal. The result is a greyer looking gold which accents the pale grey/blue sapphire beautifully.. The sapphire measures 0.25 inches in diameter and is stationed on a 16" inch white gold palladium chain.
