Emeralds

Angelina Jolie sparked the emerald trend when she wore a pair of gorgeous Lorraine Schwartz oversized teardrop earrings at the Oscars in 2009. Since then, emerald jewels have become a trademark for Jolie; the actress has been spotted wearing the gemstone most recently at the Producers Guild Awards and the New York Film Critics Awards. Now, even more of Hollywood's leading ladies, like Miranda Kerr and Debra Messing, are following suit. Emerald-hued jewels add an extra luxe touch to any ensemble — red carpet or cocktail — and look amazing against any skin tone. Want more proof?

Even if you're single and loving it, there's something alluring about being a bride. That's why we're kicking off wedding season with a month of can't-miss editorial on the best dresses, rings, shoes, and party outfits for a wedding. To kick it off, we're starting at Step 1: the ring. While few women want to resist a big, old-fashioned diamond ring, there are plenty of gorgeous, nontraditional options if you're planning to get engaged and want something different. We combed the market for 15 beautiful, unique rings that, quite frankly, don't require you to plan a wedding around.

Just in time for the holidays, Cartier celebrates 100 years in America with an extensively sparkly exhibit. San Francisco's Legion of Honor is hosting an exclusive exhibit through April 18. The collection houses more than 200 objects, starting with the Belle Époque through to the 1960s and '70s; jewelry of the gilded age and art-deco period surround platinum-set diamond tiaras, mystery clocks, and exotic creatures. The real stunners are the royal pieces worn by high society and Hollywood legends; an exotic flamingo brooch made for the Duchess of Windsor, diamond bangles worn by screen legend Gloria Swanson, and — my favorite — Princess Grace of Monaco's Cartier engagement jewelry (pictured). There's no denying Cartier's pukka power. Here's to another 100 years of diamonds, rubies, and emeralds.
