This ring is adjustable and can fit most sizes. However, if there's a particular size you'd like the ring to fit, leave a note in the comments box when you check out & we will pre-size it for you! Our rings are made of aluminum, so they're lightweight and will not tarnish, or turn your skin green. Aluminum is also hypoallergenic and is safe to wear in water. Due to its handmade nature, the final product may vary slightly from the photo. Each ring is made to order, so please allow 1-2 weeks before your order ships.
