The Etoile de Mer Diamond Ring sets a diamond starfish on a gold band, on approx. 3.50 g of solid 18K gold (750 hallmark), in yellow, rose or white gold, with a certificate of authenticity. At 0.05 ct the starfish is marked in stone rather than filled with it — note that the Étoile de Mer Ring carries four times the diamond, 0.20 ct, on the identical 3.50 g of gold. So the two are a genuine choice between a gold-led and a stone-led reading of the same motif. Product Details 18K Gold WeightApprox. 3.50 g Diamond WeightApprox. 0.05 ct MotifDiamond-set starfish
