The 2010 Academy Awards brought out the stars and the best (or worst) of fashion.  As usual, Oscars jewelry was prominently on display, whether deliberately small and subtle or large and opulent.  Each year, as celebrities crowd the red carpet, they are asked “who are you wearing?”  This year, not only was it the tuxedos and gowns getting attention, but the amazing array of diamond jewelry. 

Kate Winslet had perhaps the most distinctive jewelry at the famed awards show.  To complement her silver Yves St. Laurent gown, she chose a Tiffany necklace made with emerald-cut white and yellow diamonds with matching earrings and cuff.  Their total estimated value is over $2.5 million. 

Carey Mulligan made her debut at the show wearing what the Diamond Information Council called “the most stunning diamond moment of the night”.  She chose 19th-Century diamond and diamond briolette earrings and a 2.5 carat, pear-shaped Everlon Diamond Knot ring, all by Fred Leighton.  Kwiat diamond jewelers created the look for Best Supporting Actress Nominee Anna Kendrick, who wore diamond pendant earrings, an oval diamond bracelet, and diamond web ring.  Amanda Seyfried, more noticed for her choice of gown, was wearing 250 carats of Lorraine Schwartz diamonds in champagne, brown, and mint-colored bracelets.

Dame Helen Mirren went subtle with her selections of the Badgley Mischka gown and diamond jewelry by the famed house of Chopard.  On the other side of the spectrum was designer Tom Ford, whose shirt studs were all princess-cut diamonds, and a tuxedo made, of course, by Tom Ford. 

Stacking bracelets was certainly on-trend this year.  Sarah Jessica Parker wore a 1950s diamond swirl bracelet with one of cognac-colored flexible diamonds and another of rose-cut diamonds.  She complemented those with an antique cushion-cut 9-carat diamond ring and 19th-Century diamond cluster earrings, all from Fred Leighton.  Penelope Cruz also wore a number of bracelets, combining a 23-carat Asscher-cut diamond bracelet with a 28-carat emerald-cut bracelet, and a Diamond Line bracelet—all by Chopard.  Mariah Carey stacked H. Stern tennis bracelets to go with a diamond cuff by the same designer.  Kathy Bates was adorned with over 54 carats in her stacked Rough Diamond Astra Bangles, another 62.48 carats on her Rough Diamond Astra Necklace, and yet another 56.59 carats on Rough Diamond Astra Earrings.

The stars were sparkling on Oscar night 2010.  As expected, celebrities went all out in their displays of fashion and diamond jewelry.  Trends were easy to pick out, but one thing remained constant: everyone wanted to have the most beautiful diamond jewelry on the red carpet.
