As part of our Wearable Minerals Jewelry Collection, the oblong Brut Amethyst Point Bracelet features a raw stone displayed on a classic, gold-plated chain. Celebrated by ancient cultures through to present day, the amethyst ranges in hue from pale to deep purple. The crystal quartz, which is known as a stone that brings clarity and good sleep, actually is known to change based on the person it adorns or on the temperature of a room.
