Cheryl Cole Launches Capsule Collection With Promise Ring

British singer Cheryl Cole has a unique tie-in with her new single, "Promise This." Last week was at the launch party for "Promise", a design collaboration with jeweler, Fawaz Gruosi, the founder of de Grisogono. The first piece from her new capsule collection is a rose gold and blackened silver ring that spells out the word "Promise" with a heart-like "m." The ring is designed to be worn on the pinky finger. It sells for 920 euros (approximately $1,270). At the Cannes Film Festival this summer, the company paid Cole £250,000 for a 30-minute performance. Several of Cole's Girls Aloud bandmates showed up to support her at the event which was the first appearance she made in several months after suffering a bout of malaria.
