In the market for an engagement ring? Forget the usual brick-and-mortar browsing — head to your iPhone's app store and download Tiffany & Co.'s free Engagement Ring Finder. Scroll through the jeweler's collection by metal, diamond shape, setting, and design. See prices and actual sizes and match each ring to a wedding band, too.
If you are looking to surprise your partner, surreptitiously snag one of her rings, place it on the iPhone screen, and align the ring with the correct circle. Better than guessing, right? (I took the size finder for a test drive, and my ring matches the 5.5 size.)
