This large smoky quartz is polished smooth in it's natural shape, it measures 4.5cm x 4.5cm and is netted in a navy color cord. This smoky quartz has a nice yellow tint to it which is my favorite (almost like a smoky citrine). Smoky quartz is a superb grounding stone and a great antidote to stress. Smoky quartz helps you to tolerate difficult times with equanimity, fortifying resolve. Many people use smoky quartz to ground themselves after meditation. This piece is approx. 30" in length and can be adjusted with a simple knot to your desired length, it has a small bronze circle at the top to symbolize unity - this piece is one of a kind and as you see in the photo.
