9ct Diamond and Amethyst Drop EarringsDiamond and Amethyst Earrings These 9ct rose gold drop earrings are designed in a double drop style. The main feature is an 8x6mm oval cut amethyst, which is suspended below a smaller, sparkling diamond. The 2mm diamond is a brilliant cut stone, meaning it has been faceted to create a high level of sparkle. The warm, pinkish tone of the 9ct rose gold provides a complementary setting for both the purple amethyst and the clear diamond.
