She was surrounded by some of the world’s most beautiful diamond jewels, but Blake Lively still managed to outshine them at the unveiling of Van Cleef & Arpels redesigned New York 5th Avenue Flagship Maison on Tuesday evening.

The 26-year-old wife of hunky actor Ryan Reynolds looked both stylish and sexy in a lingerie-inspired silk and lace black gown from Marchesa’s Spring Summer 14 line. The delicate attire featured pale pastel floral threadwork embroidery, Chantilly lace cutouts and tulle flounce skirt and was perfectly slinky over the star’s slender figure.

The Savages star wore a vintage-style fur jacket as she made her grand entrance down the set of stairs to the store, and she boosted her already statuesque five foot ten height in a pair of black embellished heels. But it was Blake’s stunning diamond earrings, matching bracelet and ring that really completed the ensemble, with the accessories lighting up like a Christmas tree under the flashbulbs.

However, the jewels had some stiff competition from Blake’s Lorianne Schwartz engagement ring, given to her by her hubby Ryan. The actress continued the Old Hollywood theme in her hair and makeup, styling her blonde tresses in loose curls and applying some crimson lipstick to her pout.
