The gem at the centre of the "Contrarian" opal ring is an exquisitely unusual black opal (10.97ct) from Lightning Ridge in Australia. It showcases a rare natural marriage of two colour palates in one gemstone. Warm play of colours versus cold play of colours. A truly fascinating affair. With so much to show, this gem requires a simple yet defined setting. A sparkle of diamonds on the side adds a finishing touch.
