Marquise and round emerald together in a pendant on an 18K yellow gold over sterling silver Singapore chain creates a colored gemstone necklace where two different emerald cut shapes contribute complementary visual qualities: the marquise's pointed oval delivers the elongated, directional fire of that distinctive cut, while the round brilliant provides the familiar omnidirectional sparkle. Real emerald in both cuts at 0.53 total carats - emerald's characteristic vivid green with its individual jardin inclusions that make each stone unique. In warm gold over sterling, the green emerald appears richer and more saturated than in platinum-enhanced sterling silver.
