Are Meghan Markle's rings a hint about her due date?

It does all make sense!

Meghan Markle and Prince Harry announced the exciting news that they were expecting their first child together earlier this month, just days before the newlyweds departed on their royal tour of Australia, New Zealand, Fiji and the kingdom of Tonga.

And now that the Duke and Duchess of Sussex are well into their royal tour, the buzz hasn’t died down with fans and royal experts speculating about everything from the future baby names (apparently Harry likes Harriet) to the predicted god parents (George and Amal, anyone?)

But the real question on everyone’s lips is 'when is the baby due?' When Kensington Palace announced the Duchess of Sussex’s pregnancy, it was announced that the newborn was expected in Spring 2019. When however in Spring 2019 is not yet known.

Fans have been predicting due dates based on the size of Meghan’s baby bump and the announcement date, with most people announcing their pregnancies after their first trimester.

During the Duke and Duchess’ royal tour, Meghan was spotted wearing three gold stacking rings by the jewellery brand, Ecksand.

But on closer inspection these three rings aren't just any stacking rings, they are actually each decorated with a birthstone.

The stones in question? Green peridot, diamond and sapphire.

Meghan's August birthday means green peridot is her birthstone, and Prince Harry's September date grants him a sapphire birth stone.

So that just leaves one stone unaccounted for - the diamond.

Eagle-eyed fans are speculating therefore that this diamond represents the future baby. But what month does diamond represent? April.

Yes, as far as fan theories go, this one certainly seems to have legs.

Will baby Sussex be born in April? We'll have to wait and see, but we wouldn't be surprised!

Congratulations again to Harry and Meghan!
