Handmade in Brooklyn, NY By Etymology Jewelry. A bright, saturated, sparkling rose quartz crystal is the focal point in this eye catching cuff. An easy way to rock your favorite crystal, these gem stones are securely and tightly hand wire wrapped to the vintage brass cuff base. The substantial cuffs themselves are from the 1970s originally. Rose quartz is known as a stone to bring about love and strengthen relationships. Cuffs best fit average wrists, and  can be slightly adjusted.
