The most unique celebrity engagement rings

![Matt Rutler spent over a year preparing his heart-warming Valentine's proposal and just as much thought went into designing the engagement ring. Christina shared a photo of her new sparkler on Twitter, with the caption: "He asked and I said."
Matt had taken two of Christina's favourite rings to create something that incorporated both designs into one. The result was an intricate oval-cut diamond ring, featuring different stones that represent different aspects of Matt and Christina's relationship.
"The actual band weaves and intertwines [the] diamonds," an insider told People. "Every connecting criss-cross symbolises how their paths crossed."
The rock also features nine special multi-colour gemstones underneath the band that aren't visible when the ring is worn.

Lady Gaga had one of the sweetest proposals, quite literally. The Just Dance singer, who is engaged to Taylor Kinney, was at first presented with a joke "candy" ring made of sweets on Valentine's Day.
"First he gave me a Ring Pop," Lady Gaga told Access Hollywood. "That was kind of amazing and I was crying, I was so excited. I said, 'Yes!' right away. And then he pulled out the heart-shaped diamond. First it was candy. I was happy with the candy."
Lady Gaga's actual ring was a beautiful heart-shaped, 10-carat rock. It features the initials T and S in white diamonds on the band, as the singer's real name is Stephanie, separated by another heart-shaped symbol.
"He gave me his heart on Valentine's Day, and I said YES!" Lady Gaga, 28, captioned her Instagram snap of the ring.
