Product Description CZs by the Yard are one of the hottest necklace styles. If you want to be trendy but unique at the same time, you will love this 16" CZ Cubes by the Yard. Rather than having single czs spaced across this sterling silver chain, there are four 3-Dimensional cubes spaced across the front of this chain. This necklace comes complete with a 2 inch extender so that it can be adjusted and worn from anywhere between 16 and 18 inches in length.
