'Shahs of Sunset' Star: Mike Shouhed Can Keep His Money and the Stupid Diamond

"Shahs of Sunset" star Jessica Parido wants to wash her hands clean of husband Mike Shouhed, and she's willing to give back her 4.5 carat rock to do it.

Sources close to Jess tell us when she walked out on Mike in August she left with only two small bags and her engagement ring ... worth around $200k. She left behind their two dogs and her wardrobe (mostly purchased by Mike) because she wants nothing to do with him or his money.

Although the box for spousal support was checked on the divorce docs -- we're told it was a mistake on her lawyer's part ... since Jessica doesn't want a dime.

Jess and Mike were only married for 4 months when she walked out. As for the wedding gifts ... that might have to be sorted out in court, since they haven't yet discussed what to do with them. They haven't even sent 'thank you' notes yet!

We're told their split will be featured on the next season of 'Shahs.'
