Christina Aguilera's new fiance spent a year designing her engagement ring.
The 33-year-old singer's boyfriend, Matt Rutler, popped the question on Valentine's Day (14.02.14) and he spent months planning the proposal because he wanted to "reflect" their "journey" in the jewellery.
A source told Us Weekly: "Matt has been working on the ring for over a year and been working on the proposal for several months.
"Matt spent a year's time mastering all the specific details with the designer to signify their love and their journey together - it's all reflected in the ring."
Matt - who has been dating Christina since they met on the set of her 2010 movie 'Burlesque', on which he was a production assistant - took inspiration from two of the 'Beautiful' hitmaker's favourite pieces of jewellery and thought carefully about the meaning behind the nine gemstones which accompany the diamond.
The source continued: "Matt knew what her two favourite rings were and married them together into one, incorporating all the details that she specifically loved. Every jewel and diamond placing has a reason and meaning for being placed there."
The coloured gemstones were placed beneath the main diamond "so they always touch her actual skin in forever-encouraging love ... and surrounding her at all times."
The band is also woven with diamonds to symbolise how the couple's bond will continue to grow stronger.
Christina was previously married to music executive Jordan Bratman, for five years until 2010, and they have six-year-old son Max together.

Matthew McConaughey has a "lot to be thankful for".
The 44-year-old actor has won a string of awards for his portrayal of AIDS victim Ron Woodruff in 'Dallas Buyers Club' and is "proud" of the recognition - including an Oscar nomination for Best Actor - his work is receiving.
He said: "For the next two months, I'm playing the character of Matthew McConaughey, an actor proud of the films he's been in.
"And if any of those films or [my] performances are in awards shows, [I'm] going to go, heart high and head up, and look them all in the eye and say, 'Damn right this is a great time in my career.' That's the role I'm in now. I've got a lot to be thankful for."
Matthew - who has children Levi, five, Vida, four, and Livingston, 13 months, with wife Camila Alves - famously shed over 40lbs to play Ron but he says having the focus and dedication the role needed was "exciting".
He told Variety: "I've got a saying; When faced with the inevitable, get relative. The inevitable was, I'm going to do this. I've got support from my family that insulates me.
"I surrounded myself with everything I needed to go on this adventure. And the focus was exciting. I said to myself, 'We're taking a trip, McConaughey. This is a story you want to tell. Those adventures you talk about - you're on one now.' "
And he claims the "clarity" his weightloss gave him was tough on those around him.
He added: "I went from being cranky to hyper aware. That clarity is hard on other people, because my bulls**t meter was zero. I was like, 'Speak up. No adjectives or adverbs. Just nouns and verbs. Speak!' "
