My favorite part of my engagement ring, Taylor and Lorraine designed "T💗S" in white diamonds on the band. 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 smiling!!

This ring gets more and more impressive by the day.

On Wednesday, Lady Gaga showed off some very personal detailing from her heart-shaped engagement ring from new fiancé Taylor Kinney. The bottom of the glittering band features the couple’s initials — a “T” for Taylor and an “S” for Gaga’s birth name, Stefani, connected with a heart.

“My favorite part of my engagement ring,” read the caption of the blinding snapshot from Gaga (whose full birth name is Stefani Germanotta), 28. “Taylor and Lorraine [Schwartz] designed ‘TS’ in white diamonds on the band. 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 smiling.”

The ring’s designer, Lorraine Schwartz — also the woman behind tot North West’s impressive diamond studs — said creating the ring was no easy feat.

“The stone is big and quite beautiful, and actually more expensive than some of the estimates I have read,” Schwartz told InStyle of Gaga’s ring. “It’s a challenge to get an excellent heart shape with perfections — the shoulders of the gem have to be totally symmetrical; Lady Gaga’s is all that.”

A report from E! News estimated the ring could be worth up to $400,000.

Gaga and “Chicago Fire” star Kinney, 30, got engaged on Valentine’s Day and have been dating since 2011.
