Prince Albert II of Monaco and his wife Princess Charlene were among a full room of celebrities and royalty who attended the Montblanc Champaign Brunch at the Hotel Bel-Air in Los Angeles Saturday to get an up close view of the Collection Princesse Grace de Monaco. It was a final chance for many of the guests to choose a Montblanc piece to wear on the red carpet at the Oscars, being held Sunday.

It was the first time Montblanc showcased the complete collection, which is intended to honor the style and majesty of one of the 20th century’s most revered leading women. The collection is designed as a tribute to Princess Grace of Monaco, who is regarded by many as the epitome of classic beauty. The collection features fine and high jewelry as well as writing instruments and timepieces in the Swiss watch-making tradition.

Oscar-Worthy Jewelry

The Collier Entier Romanov by Fabergé is set with 2,225 gemstones totaling 363.48 carats. It includes 79 emeralds totaling 186.85 carats, featuring sugar-loaf cabochons and a single pear-shaped drop of 30.65 carats. The diamond include 1,991 round white diamonds totaling 98.15 carats, 151 rose cut diamonds, of 43.29 carats, 0.67-carat rose diamond, and a pear-shaped rose cut diamond of 3.48 carats. The choker detaches from the collar, allowing the two necklaces to be worn separately, while the choker can be worn alone or with the emerald drop pendant.

It’s not only Hollywood’s finest who will be under the glare of the international spotlight as they stroll the red carpet and appear on stage for the 84th Annual Academy Awards. What they wear will be under the scrutiny of fashion experts and the general public—and that includes the jewelry they choose.

Leading style expert Michael O'Connor—who is hosting StyleLab's styling event for Academy Award nominees, presenters and stylists—says that there will not be one dominate color this year. “Bright and vibrant colored gemstones that were big in past decades including pink, blue, orange and green, will make a resurgence.”

O'Connor, who curated a selection of one-of-a-kind jewelry pieces from world-renowned designers for celebrities to borrow for the red carpet, says large pieces will be prevalent on the Red Carpet, from “chunky cuff styles with geometric shapes and vintage designs” to “oversized drop or chandelier earrings that practically touch the collarbone.”

Following Christie's Elizabeth Taylor auction, look for vintage pieces to take center stage as well. In fact, maybe statement pieces owned by the late movie star will make an appearance. After all, the renowned Italian jewelry house, Bulgari, reportedly purchased $20 million of its own jewelry at the auction. The speculation is that it will be used for a museum. What better way to announce the museum and make a bold statement than to have a multi-million piece of jewelry adorn one of the world’s top actresses.

Another company that is bringing in the nostalgia is Montblanc. It has created several lines of haute joaillerie, timepieces and writing instruments that honor the Hollywood actress and first lady of Monaco, Princess Grace. These items along with others by the venerable brand are being presented at its own “Styling Lounge” showroom.

The famed luxury jewelry house, Fabergé, has been making a comeback and it isn’t shy about letting Angelina Jolie know that it has an emerald and diamond necklace(top photo) that it wants the international star to wear. Set with 2,225 gemstones and 2,043 diamonds, the choker detaches from the collar, allowing the two necklaces to be worn separately, while the choker can be worn alone or with the emerald drop pendant.
