Finally, there's a way to coordinate your jewelry with your water bottle. California jewelry designer Anjanette Sinesio recently founded Gem-Water (from $78 to $340), a company that sells a reusable water bottle that contains a removable glass pod filled with opals, garnets, emeralds, amethyst, quartz, or diamonds. The company, which also sells decanters, claims that the gemstones "enliven your water, restoring its crystal structure to the quality of actual spring water." Whether or not you believe in the transformative energy of crystals, there's no denying their accessorizing potential.
