Savannah Brinson has stood by NBA star LeBron James through thick and thin and the pair have been dating since since high school and have two children.

So it makes sense that after all that time, the NBA star finally asked for his longtime love's hand with an impressive, off-the-charts engagement ring!

"LeBron rules, on and off the courts! He scored a slam-dunk with this magnificent platinum and diamond engagement ring, featuring a 7-carat pear-shaped center diamond with classic tapered baguette sides," jewelry expert Michael O'Connor told Us Weekly. "We haven’t really seen this style of ring with a large pear-shaped center diamond since another great love affair: Richard Burton and Elizabeth Taylor!"
