Sterling Silver Snap and Set mountings look great and are so easy to use! Just lay your favorite faceted stone face down on a flat surface, push the earring down on top of the stone and it will snap perfectly into place. Beautiful earrings instantly! Snap and Set mountings work best with natural stones, CZ’s, and other synthetic stones, but are not recommended for use with foil back stones such as a Swarovski Xilion Crystals.
