Tiny. The price tag had 24K typed on one side and 18K with the Bernini Logo on the other side. Go figure! And, when will I ever learn to read the product descriptions more closely?! When will I ever remember to bring out my measuring tape to understand just exactly how small 5.5mm really is?! Oh well. Cute. Tiny. Gold (plate). Only recommend if you are small, or have short hair, or are buying for a child.
