Lady Gaga Engagement Ring [PHOTO]: 'Chicago Fire' Taylor Kinney Surprises Mother Monster With Band Design

Lady Gaga might have just taken the engagement ring game to a whole new level as her boyfriend and now fiancé Taylor Kinney surprised her with the most fabulous heart-shaped engagement ring to ever grace the Earth. However, Mother Monster has given her fan another reason to be super jealous of her new piece of bling, as the diamond was only the beginning.

The star took to her Instagram account to post what the back of the ring looks like, and can we just say how incredibly jealous of it we are?

"My favorite part of my engagement ring, Taylor and Lorraine designed 'T (heart) S' in white diamonds on the band," the singer said, which stands for Taylor loves Stefani Germanotta, Gaga's real name. "He always called me by my birth name. Since our very first date. I'm such a happy bride-to-be! I can't stop smilling!"

The Chicago Fire star popped the question to Gaga on Valentine's Day with the heart-shaped diamond, which world-renowned jeweler Lorraine Schwartz helped him design.

Lorraine reached out to E! News, saying that the piece was "the most beautiful," as well as a "high quality" diamond. She also sent the happy couple a congratulatory message, saying, "Congratulations to this wonderful romantic and super cool couple! Wishing you all the happiness in the world."

The site also speculated at how much the ring might have cost, thanks to the help of Simon G. Jewelry CEO, Zaven Ghanimian.

"Lady Gaga's center stone is a heart-shaped diamond, approximately 6 carats," the jeweler explained. "I would estimate at least SI1 clarity or better, G color or better. For a stone of this size and quality, the price could be up to $400,000."

Now ladies and gents, this is the kind of love to aim for!
