J Lo She's Still Got that $1.8 Mil Engagement Ring!!!

J Lo and A-Rod may have broken up, but there are still some housekeeping matters to tend to  .... notably, who gets the $1.8 million engagement ring?

Sources with direct knowledge tell TMZ ... J Lo still has the ring in her possession. As you may know, an engagement ring legally is a "gift in contemplation of marriage." When the couple breaks up before hitting the alter, in most states the person who proposes gets the ring back.

Our sources say there's been no discussion between J Lo and A-Rod over the fate of the ring. However, our sources are quick to add ... the former couple exchanged "massive amounts of jewelry." A-Rod bedazzled J Lo with all sorts of bling, and she fortified his massive watch collection. So, they could just call it a wash, but they haven't decided yet.

We're told the engagement ring is NOT in the Dominican Republic, where J Lo's been shooting a movie. She didn't want it lying around every day while she films ... for security reasons.

Our sources say there will be no conflict over jewelry ... they are getting along well, and even plan to stay in business together, so don't look for J Lo and A-Rod on a "Judge Judy" episode.
