This adjustable sliding knot bracelet features 6 and 8 mm black Lava beads and 8mm Chakra gemstones: Amethyst (Crown Chakra), Sodalite (Third Eye Chakra), Magnesite (Throat Chakra), Green Aventurine (Heart Chakra), Tiger�s Eye (Solar Plexus Chakra), Carnelian (Sacral Chakra), Red Agate (Root Chakra). Lava beads are lightweight volcanic rock and, being porous, can be used as diffuser beads to hold essential oils (please check that any dye does not come out of the beads first). Lava beads are also thought to alleviate anxiety, promote emotional tranquillity and bring calmness and feelings of relaxation, making them a great choice in Chakra jewellery. Finished with a sliding knot, the bracelet is fully adjustable, fitting most wrist sizes, and can be altered for maximum comfort. Wear on its own or stacked with other bracelets, this hand knotted macrame friendship bracelet makes a great gift for a loved one, friend or just for yourself.
