Take a look at Jessica Biel’s engagement ring! While the 30-year-old actress hasn’t been one to show off her sparkler ever since she and fiancé Justin Timberlake confirmed their news in January, the ring made a public debut yesterday when she went out with her beau in Los Angeles. And it’s a rock—the custom piece features a large square-cut diamond in a vintage-inspired setting. (See a larger photo below.)
