This necklace is 21” long. The wide base of the neck is 1” wide. The multi drops are 6” at the longest, and 1/2” at their shortest. This necklace has some basic changes made. For example, someone removed the original chain and substituted an 8” length gold chain and then took the latch/hook and changed it into a lobster latch. We are selling as is because we don’t know our customer’s needs. If you wish us to change the lobster claw, we will be glad to do it.
