I purchased this necklace almost 20 years ago strictly because it was unique and being sold at almost nothing. I have often times been at the point where i almost donated it. I am a child of the 1980's and perhaps unknowingly had memories of similar objects and thus saw the beauty of it. The necklace has no markings on it. The only thing is the green metal tab on the end of necklace. Can someone please help me identify? I do not have a place to store this item and am wanting to sell it or donate it depending on what it is. PLEASE HELP. I appreciate it.
