Fiorello Necklace, Sterling Silver with Black Rhodium and White Topaz Gem. 
Clasps closed under your chin with the hinged ring and the Flower pendant enhnacer snaps to the ring. So you you can wear them separately or together. Consider adding another pendant this chain or wearing 2 together. I personally snap in the Red Hot Heart when I wear together or I wear them individually on a velvet ribbon. So fun to mix it up and find your own style! BTW this was the necklace Beyoncé wore in her visual album...Check it out!
 
Chain measures 18 1/2 inches in length  Flower 2 3/4 tall X 2 1/8 wide
