Beautiful Ralph Lauren necklace! Silver hardware Blue ribbon necklace wit extension clasp closure RL is etched inside the stone and on the end of the clasp dangle (as seen in picture) A bit dusty behind the stone, unsure what it is made of it could be sapphire, glass or some sort of stone. When the sun shines through it, you could see how shiney it looks! Comment if you have any questions. Reasonable offers welcome! :) Thank you for stopping by my closet!
