People celebrate special occasions by decorating things with baubles, as evidenced by hanging ornaments on Christmas trees and emptying drums of diamonds over winning coaches. Bauble up with today's Groupon: for $49, you get $100 worth of interchangeable fine jewelry at Charlotte Ehinger-Schwarz.

Fourth-generation goldsmith Wolf-Peter Schwarz designs and oversees the production of Charlotte Ehinger-Schwarz’s lauded, interchangeable jewelry, which is distributed to and sold at ateliers around the world, including a location in Memphis. Gemstones and pearls detach from one piece of jewelry thanks to a squeeze from a pair of jewelling tweezers, then snap on to another piece like a drill bit burrowing straight for the beholder’s heart. The online catalog details the extensive 2011 collection, letting eyes envision circles of stainless steel ($40) and bruyère wood ($65), which brings out the dimensions of silver-set amber ($110+) and amethyst ($150+). Sets can then swap jewelry pieces crafted from silver, gold, platinum, and Swedish steel, such as a sterling-silver ring ($370).
