'Real Housewives' Jill Zarin -- Check Out My $19,000 Ring ... Courtesy of Elizabeth Taylor

Former "Real Housewives of NYC" star Jill Zarin ain't bitter she got the boot from the show -- telling TMZ, she's still got a filthy rich husband ... and she proved it by flashing the $19,000 ring he bought her last month at Elizabeth Taylor's jewelry collection.

Honestly, we have no idea how she walked around with that thing last night in New York -- because it's freaking MASSIVE ... a gemstone the size of a baby's fist, designed by famed jeweler Zohrab Istanboulian, and once worn by Liz Taylor herself.

The ET auction took place last month in NYC -- and you may recall ... rich people of all shapes and sizes were at each other's throats to get their grubby mitts on the late legend's bling.

Kim Kardashian herself dropped $65,000 on a couple bracelets. Must be nice.
