CVC Stones - CVC Stones’ 18kt gold Goth necklace is thread with a smooth black pebble that embodies French founder Charles de Viel Castel’s fascination with the natural world. It’s handcrafted by a goldsmith in New York and encrusted with 0.28ct worth of white round-cut bezel-set diamonds for a touch of sparkle. Adjust the fine cable chain to your desired length and dress it up and down throughout the week.
