Now that "Glee" star Naya Rivera and Big Sean are engaged, it's going to be hard for the rapper to top a gift as gorgeous as Rivera's shiny new engagement ring, but he managed to pull off quite a complementary piece for the holidays, Us Weekly reports.

Rivera Instagrammed a photo of a new, expensive-looking diamond necklace from her husband-to-be alongside her massive ring on Dec. 25, captioning the pic, "Merry Christmas. photo and gift credit @bigsean."

Her followers responded with plenty of compliments and even adoration, one writing, "I wanna be you" while another estimated that her ring is "at least $30,000," if not more.

Rivera and Big Sean confirmed their engagement back in October, just six months after going public with a red carpet debut together. The 26-year-old actress first showed off her ring at Latina magazine's Hollywood Hot List party at the Redbury Hotel in Hollywood, according to Us Weekly.

As for when the two will tie the knot, Big Sean said during an interview with during an interview with Rap-Up TV at Power 106′s Cali Christmas, "That's for us to know."
