Whether they're from Beverly Hills or New Jersey, the Real Housewives across all franchises have one thing in common: __seriously__bling-y engagement rings. Lisa Vanderpump's mega-watt sparkler caught our eye when we were browsing red carpet photos, which got us wondering what the rest of the ladies' engagement rings looked like. So we decided to find out.

Here's your comprehensive guide to the left hands of all the Real Housewives. (We limited our search to current stars and skipped Miami (which Andy Cohen has called "dead in the water") as well as D.C., which is off the air, and Potomac and Dallas, which have yet to debut.) One weird commonality from coast to coast: Round-cut center stones are by far the most popular, probably because they're widely regarded as the sparkliest, and all of these ladies love sparkle.

*Everyone is either divorced or widowed; there's not a single engagement ring among them. *NEW JERSEY

Teresa Giudice

Teresa's engagement ring features a round center stone flanked by tapered baguettes. She pairs it with a hefty band featuring more round diamonds.

Melissa Gorga

It took some digging to figure out exactly what's happening on Melissa's left hand. At first glance it looks like Joe proposed with a round diamond in a diamond halo with a trillion side stone on either side of the center stone. The bands on either side appear to be separate rings—until you look at the side of the ring.
