These 18K yellow gold Andrea Fohrman opal and diamond hook earrings are designed in the US. Suitable for pierced ears, they feature Australian opal doublets surrounded by pavé white diamonds. Queen Victoria's favourite gemstone was the opal, which means when you wear these Andrea Fohrman earrings, you can recite such gems as, 'the important thing is not what they think of me, but what I think of them.'
