These cluster earrings have what appear to be white/ transparent, black and grey stones. Not sure what the stones are made of so l don't want to guess and be wrong. They are secured in the ear with these great omega style backings for pierced ears. A tad tarnished, May have scratches or scuffs but I don't see any. You will be pleased! They are no longer available in stores or on their website. Great to add to your rock candy collection! These are wonderful for a black tie event Please see my other listings for more Ippolita, David Yurman, and Tiffany & Co. jewelry also!
