This is a four strand graduated branch coral necklace. The ornate clasp is made of some type of brass like metal and measures 7/8" square. The shortest strand measures 15.50" and the longest 17". The width of the coral at the center part of the strands is approximately 1/2" tapering down to 1/4". The clasp is tight and secure. I don't see any damage to any of the coral pieces.
