The Merlot is the smallest of the Cluster series EarClimberZ. It is 1 inch in length. It has 4 Swarovski crystals, sizes 3 and 4 mm and a delicate wire zigzag between the top crystal and the cluster that covers the piercing hole on the ear. The Swarovski Crystal AB is a clear crystal with an Aurora Boreales coating to reflect light beautifully. It is the birth stone used for April.
