She was overjoyed to receive a Valentine's Day proposal from longtime boyfriend Matthew Rutler, but Christina Aguilera may be surprised at how much thought and effort went into the big moment.

On Friday (February 14), the film producer popped the question in Hawaii with a giant diamond sparkler.

According to People, he'd been working on designing the ring for over a year with care taken to make sure each part represented their three-year relationship.

A source familiar with the ring told the magazine, "The actual band weaves and intertwines [the] diamonds. Every connecting criss-cross symbolizes how their paths crossed … the ring narrows at the base [to] reflect how their bond continues to grow closer and stronger over time. There are nine special multi-color gemstones that you cannot see. They all symbolize something meaningful to the couple. Christina is very spiritual and having the stones touch her actual skin will emit positive energies surrounding her at all times. They represent things like love, protection and healing.”
