This unique design by Quore puts one gemstone into another. Per the designer’s website, “The Wheel of Light Ring is the ultimate cocktail ring, it is a shining statement piece. A paraiba tourmaline is set inside faceted quartz crystal in an architecturally designed upright setting. Light enters through the top and through the sides. Available in 18k yellow, rose and white gold or silver.” Stones inset also can be ruby or emerald, rather than tourmaline.

Prices range from USD$700 for the silver ring with one combination of inset stones, to $4,500.
