Buffalo Bills defensive end Mario Williams filed a lawsuit against his ex-fiancée Erin Marzouki in Houston on Monday for a $785,000 engagement ring. The ring is a GIA certified radiant cut diamond weighing 10.04 carats. The lawsuit also alleges that Marzouki charged $108,000 between January 1, 2012 and December 31, 2012 on Williams' American Express card. Williams also claims that "additional luxurious items" were purchased to the tune of $230,000.

According to CourtHouseNews.com, Williams is also asking for a restraining order and a writ of sequestration to stop Marzouki from selling the ring.

"The termination of the relationship was solely caused by defendant," the complaint states. "Defendant never intended to marry plaintiff and used the relationship as a means to get to plaintiff's money and acquire gifts. Defendant has absconded with the diamond engagement ring. Plaintiff has demanded that defendant return the diamond engagement ring, but defendant has failed and refused to do so."
