The Tiffany & Co. Engagement Ring Finder app for iPhones allows brides and grooms to use their iPhone, iPod Touch, or iPad to find the perfect diamond ring.

For the men, the Tiffany iPhone app will show rings in their actual size, so they’re more likely to compare the on-screen rings with their partners.

The “ring sizer” aims to simplify ring sizing by stealing one of her rings, placing it on the screen and waiting for the correct ring size to pop up!

For the woman, the Tiffany iPhone app makes designing the perfect ring simple, all through the iPhone app.

Browsing the collection according to shape, setting, metal or design is equally simple. Each style may be viewed with diamonds of six different carat sizes.

Users may zoom in on a ring’s exquisite details, pair the rings with wedding bands, and save or share their favorites via e-mail, Facebook and Twitter.

In addition, users can make an appointment for a diamond consultation via phone or e-mail.

The app will appear in English (in the U.S., U.K., Canada and Australia) and Japanese, with prices in local currency.

Prices will not appear in the Chinese version or in the international English version that is available to all other countries.

Download the free Tiffany & Co. Engagement Ring Finder app directly from the iTunes store.
