Put A Ring On It

Waiting for your boyfriend to propose but worried that he won't give you the ring you really want? There's an app for that. Tiffany & Co. just launched an engagement ring app for the iPhone so you can design your dream ring. Pick from classic diamond shapes, settings and various metals, or browse the jeweler's stable of ready-made designs. But the most high-tech feature is the ring sizer: All you do is place a ring on the touch screen and it brings up the best size match for your finger. Then you can email your design off to friends, family and your beau — and keep your fingers crossed!
