Gellner 18kt rose gold 39" Castaway necklace featuring 21.150-25.850ctw (average) round brilliant diamond pipes and accented with 9 x 7-8mm silver Tahitian-cultured round pearl stations. Only genuine connoisseurs know how to play the game with contrasts: perfection is achieved only when each facet harmoniously complements all the others. And that’s exactly what Castaway does! Castaway impressively links inner worth and outward effect by combining understatement and star appeal.
