Blueberry colored rubber (neoprene) is a delicious color in a great material. A jewelry design incorporating the blueberry color would be just wonderful. Unlike natural rubber, neoprene will not burn or tarnish silver. Ordering by the foot leaves it up to you how long you want your necklace or bracelet to be. At Artbeads.com, we consider your convenience! The neoprene rubber material is latex-free, so it's safe for anyone to wear!
