Prince Harry's engagement ring for Meghan Markle will have Diana's diamonds

Rumours about Prince Harry and actress Meghan Markle will announce their engagement this week have become stronger by the day. Now the reports about how the engagement ring will be designed have surfaced too.

Prince Harry and Suit star Markle have been together for 16 months. After wrapping up her show, it is reported that the star who plays Rachel Zane on the show is ready to move in with the Prince at his Nottingham cottage with her two dogs. Speculation about engagement being made official grew when it was reported that Harry and Meghan met with the Archbishop of Canterbury about the wedding.

According to a report in Express.co.uk, the royal has designed the ring which is made using diamonds from a broach that once belonged to his mother late Princess Diana.

In an interview with Vanity Fair in September, Meghan had revealed that the couple is really happy. "It’s really simple. We’re two people who are really happy and in love," she said.

The couple made a first official public appearance together for this year's Invictus Games. The relationship became public in last November when the prince issued a rare warning to the media to leave his 36-year-old girlfriend and her family in peace, reflecting his own battles with the press.
