Celebrities Sparkle with Loaned Jewels at the Oscars

March 3, 2014— -- Best Actress nominee Amy Adams may not have taken home a statuette from the 86th annual Academy Awards on Sunday night, but by many counts she was a winner on the red carpet.

The star of "American Hustle" posed confidently for paparazzi photos while wearing a strapless, sapphire Gucci gown that was accented by sparkling jewels from the 2014 Tiffany Blue Book Collection, including rhodocrosite, lapis and turquoise earrings and a yellow diamond and spessartite bead ring. Around her wrist, a bracelet with Tiffany yellow diamonds also played off of a Tiffany metro diamond band ring.

Luxury bling helped transform many of the night's attendees and gave the evening an air of royal pomp--even if none of the actresses actually had to pay for them. After all, it's always fun to play dress up. Here are five more looks dripping with jewels:

1 - Mrs. Justin Timerlake, aka actress Jessica Biel, who was a presenter at the Oscars ceremony looked romantic and regal in drop earrings and a bow bracelet with emerald-cut aquamarines and diamonds, both from the 2014 Tiffany Blue Book Collection, according to a company spokesperson. In addition, Biel wore a diamond cluster necklace, a wide diamond bracelet and a five-row diamond bracelet by Tiffany & Co.

2 - Ever the arbiter of brave yet successful fashion choices, Best Actress in a Leading Role Winner Cate Blanchett accessorized her embellished gown with giant opal drops set in white gold from Chopard.

3 - The $2 million Neil Lane necklace draped around Best Actress in a Supporting Role nominee Jennifer Lawrence's neck was no less than 100 carats.

4 - 2004 Oscar-winner Charlize Theron commanded attention at the 86th annual Academy Awards flaunting a dramatic Christian Dior Gown and dangling a 31-carat diamond cluster Harry Winston necklace in the center of her plunging deep-v neckline.

5 - Best Costume and Production Design winner Catherine Martin matched a bold gown with equally bold jewelry that included a Tiffany & Co. Schlumberger Arrows brooch from Tiffany’s 2014 Blue Book Collection, as well as a "diamond X bracelet, a flower ring with a cushion-cut pink sapphire and diamonds and a red spinel ring with spessartites and diamonds by Tiffany & Co.," according to a company spokesperson.
