Keep her guessing this holiday season and buy the lady in your life some truly unique sparkle. These lightweight earrings are actually a chain of interlocking spheres, digitally designed and created by a machine using a process called Selective Laser Sintering (SLS). This process involves selectively binding nylon powder using a laser, which allows the whole piece to be created all at once. They may be practically weightless, but your lucky lady will never forget them.
