We love these Smokey quartz. They are faceted and pick up gorgeous tones in all kinds of lighting. We paired them with peitresite. Both stones are known for their super powers to cleanse auras and chase away bad vibes. This set has been intentionally made to promote the feeling of safety and wellbeing. We strive to source our materials in sustainable and ethical ways. We want our products to be a guilt free luxury. If you have any questions please ask.
