Metal type : 14K Solid Yellow Gold Country of origin : Italy Ring(s) Inside Dimensions : 0.08" (2.03mm) Length : 8.5MM Lobster Clasp, 10.5MM with ring Product dimensions LxWxH (MM) : 10.5x3.5x1 This 14-karat yellow gold oval lobster clasp features a smooth, bright finish and an open attach ring. Complete the clasp with a plain or fancy ring on the opposite of the strand. One of the most common clasp styles, the lobster clasp offers a streamlined look and good security for all types of strands. Named for its resemblance to the action of a lobster claw, this clasp features a hook shape with a spring-operated closure. Simply press the ring at the opposite end of the strand against the closure, pushing it open enough to let the ring pass onto the hook (or press the release lever to open the closure). The spring holds the clasp closed until the lever pulls it open to release the ring.
