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.

Kate Bosworth Collaborates on JewelMint Monthly Jewelry Club

Kate Bosworth is the celebrity face behind a new costume jewelry site that uses the "push shopping" concept to attract customers to monthly deals. JewelMint, from social shopping company BeachMint, has a subscription model. Those who pay $29.99 each month can pick out one piece of jewelry designed by Bosworth and her stylist Cher Coulter (if you don't see anything one month you can skip a month). Each subscriber completes a style quiz that helps JewelMint tailor its monthly jewelry selections to each person. The designs will sell for 70 percent off of retail prices. Check out JewelMint for videos with Bosworth and Coulter explaining how it works and showing off more pieces from the collections.

As TechCrunch noted, ShoeDazzle, which is promoted by Kim Kardashian, has a similar model. Will be push shopping be the new private sale with a bunch of brands flooding the marketplace?
