Thick sterling or 14k gold-filled wire is whipped around chunks of pure natural gemstone goodness. Choose clockwise from top left: ice blue aquamarine, green/gold pyrite or deep purple amethyst. Also avail in clear quartz, not shown (same shape as amethyst). Cocktail, with a twist. Each centerpiece will vary in shape -- aquamarine is flat and oval, while the other stones are more of a tri-cut, 3D shape. Available in sizes 6, 7 and 8.
