Bronze Adjustable Stingray Ring. Manta rays symbolize grace and flow. They are "birds of the sea" as they gracefully glide though the water, often flying above the surface, as well as inches from the sandy bottom. They are sensitive to flows of energy, and can help us tap into our flow and dance with it, rather than resist. Mantas teach us to notice the nuances of energetic flows, and to navigate the varying depths of our emotions with grace. The adjustable ring sizing starts at size 7, making it ideal for sizes 6-8. As with all adjustable rings, we suggest adjusting this ring to the desired size and then leaving it alone. Our bronze is a high quality Italian alloy of copper and tin that contains an anti-tarnish compound which delays, but does not eliminate, eventual oxidation.
