are unique and rare, but there is a long tradition in the embellishment of sunglasses with sparkling gems. We have created a collection of sunglasses that use beautiful Swarovski crystals to add color, flavor, and pizazz to some of the most elegant eyewear models in the world. Swarovski crystals come in many shapes, sizes, colors and patterns, and you will see many of them here. A caution: When you use sunglasses frames that have Swarovski crystals, you need to be aware that crystals sometimes pop out of the frame. Crystals are normally glued into frames, and when an optician heats up a frame to adjust it, crystals can fall off. Once they have fallen off, there is no way to get the crystals replaced and installed into the frame, except by a jeweler.
