Heavy. Metal. Rockstar. I faceted sterling silver to look like a giant piece of 'ice.' And I don't mean the kind you slip on sweetheart. This necklace is not for the meek, it is a luxurious center of attention all focused on Y.O.U! What a stunner you are. Now go rock the house. 'Gem' is 1 1/2" x 1" Chain length: 17 3/4" long, can be adjusted. E-mail us for additional lengths.
