Prince Harry and Prince William may be at different stages in their life, but they will always be brothers. Harry proved that sentiment back in 2010 when William popped the question to Kate Middleton.

When the royal brothers lost their mother, the late Princess Diana, each of them chose one of her possessions as a keepsake. As reported by Express, Prince William chose a gold watch while Prince Harry chose her engagement ring.

As most know by now, Kate Middleton was the recipient of that engagement ring, which corroborates what Amazon Prime's "The Diana Story" shared. The documentary claimed that Harry gave the ring, which is set in 18k white gold and boasts a 12-carat oval sapphire centerpiece surrounded by 14 solitaire diamonds, to his older brother after finding out he was going to propose.

Even though since then things have gotten tenser between the brothers and Prince Harry and Prince William are on "different paths" at the moment, body language expert Judy James revealed that they are still bound together by humor.

"His laugh, when asked about the rumoured rift with his brother William, looked rueful and he paused to compose his words," James explained of Harry's reaction to being asked about the rumored rift between the brothers.

"His grin looked almost like a reflection of what he thought William’s response would be if he were asked the same question and he shoved his hands into his pockets as he told Tom 'I love him dearly' but that they have good days and bad days as brothers," she continued.

"It was clear from his grin that humor is still the tie that binds between them," James finished.
