Black, matte and porous Lava stones are featured in this simple bracelet. Match it with my white howlite stone bracelet and you have the perfect yin and yang... Opposites attract! Being that Lava beads are porous in nature, they make great essential oil diffusers. Just put a drop or 2 of your favorite essential oil on the stone; the healing scent will last up to a day! -Stones are strung on genuine silk cord -Stone size: 3mm wide -Gold beads are made with gold fill metal -Bracelet is adjustable to fit betwee 6-9 inches. Gold-fill looks the same as solid gold and can last for years or decades with proper care. Gold-fill is a great option for most people with sensitivities to cheaper metals. To keep the jewelry in its best shape-do not shower, swim or sleep in your jewelry. Keep all jewelry separately, best in airtight bags. Gemstones have varying hardness and harder ones might scratch softer stones. Found in most stores, jewelry polish pads for gold and silver are brilliant for cleaning.
