Diamonds are Karen Elson's best friend! The 34-year-old British model and singer hosted Tiffany & Co.'s relaunch of their stunning Atlas collection in NYC on Tuesday, Sept. 10.

The collection's debut was celebrated inside the Fifth Avenue store at a private, star-studded event. Elson wore a sexy red dress with her hair pulled back to better show off the gorgeous jewelry.

Fashion bloggers Aimee Song of Song of Style, Jessica Stein of Tuula and Chiara Ferragni of The Blonde Salad were also hosts for the evening. They shared global style tips featuring the Atlas collection, while enjoying music spun by New York stylista and entrepreneur DJ Hannah Bronfman.

Guests included models Doutzen Kroes, Julie Henderson, Lindsay Ellingson and others. Victoria's Secrest Angel Ellingson wore a beige Victoria Beckham dress, which was the perfect canvas for the collection.

"Since trends come and go, it's important to have jewelry that is timeless," Elson tweeted Tuesday, Sept. 10. "@tiffanyandco #TiffanyAtlas."
