(CNN) -- If your partner loves their Big Macs - then they're really going to want this.
McDonald's is giving away a Big Mac beauty.
It's a seven-layer, stackable ring called the "Bling-Mac," and Cosmo reports it's worth upwards of $12,000 dollars.
But McDonald's is giving the 18 karat gold, gem-encrusted version of it's classic sandwich away for free.
For a chance to win it, social media users must tweet out their love for the Big Mac, using the #blingmaccontest.
Mcdonald's tongue-in-cheek promotion comes with the launch of three different Big Mac sizes: Grand Big Mac, Big Mac, and Mac Junior.
