The Orbella Double Ring builds a band from two rows of solid gold beads, on approx. 6.10 g of solid 18K gold (750 hallmark), in yellow, rose or white gold, with a certificate of authenticity. No stones — rounded gold beads return light softly rather than in points, which is the whole effect. At 6.10 g this is the heaviest of the Orbella rings, well above the Double Orbella Ring at 4.0 g and the Simple Orbella at 2.00 g.
