Mandy Moore in Chopard

On Sunday, Feb. 27, swarms of celebrities turned out to the Kodak Theater in Hollywood for the 83rd annual Academy Awards. Lavish gowns stylish tuxedoes pierced the red carpet. And while we were certainly fascinated by the garments of choice worn by A-listers, were also noticed that many were spotted wearing luxury jewelry and watches by Chopard, one of the world’s most coveted luxury brands.

Mandy Moore, who performed a song from her animated feature film, Tangled wearing a pair of pave round diamond earrings set in yellow gold and a 10-carat rose cut and pear shape diamond ring with diamond 3-carat micropave in yellow gold;

Colin Firth wore a LU.C XPS watch with a black dial set in white gold.

E! News host Giuliana Rancic was live on the red carpet interviewing all the clebrities, wearing pieces from Chopard’s Animal World Collection: 77-carat grey pear shape moonstone earrings with orange, yellow, and black diamonds set in yellow and white gold and a fancy deep brown yellow 10- carat pear shape diamond ring with brown and white diamonds set in rose gold.

And while many stars attended the awards, there were just as many who chose to instead watch the show across town from the 19th annual Elton John AIDS Foundation Oscar Viewing Party. Chopard helped sponsor the event, giving both the atmosphere and the stars a little added panache and pizzazz.

Of course, the evening’s host, Sir Elton John, along with his co-host David Furnish, each sported Chopard watches.

Other guests included Chopard Co-President and Artistic Director, Caroline Gruosi-Scheufele (pictured above with Heidi Klum), who donned Chopard’s 105-carat icy quartz briolette earrings set in white gold and a 50-carat Animal World sting ray purple sapphire bracelet in white gold.

Jessalyn Gilsig, (wearing 14-carat Chopard briolette with marquise diamond earrings set in platinum and a 10-carat heart shape ring set in white gold); along with Steven Tyler, Quincy Jones, Ben Kingsley, Chase Crawford, Hayden Panettiere, Heidi Klum, Emma Roberts, Jamie Foxx, Ashley Tisdale, Vanessa Hudgens, Claire Danes, Nicole Richie, Joel Madden, Sharon and Kelly Osbourne, Sharone Stone, Tori Spelling, and many others.
