Princess Diana’s Engagement Ring
About 12 carats, as most reports state oval ceylon (sri lankan) sapphire by Garrard

Celebrity engagement rings / Meghan Markle
In short: Meghan Markle’s ring is a three-stone design by Prince Harry: a cushion-cut diamond he sourced from Botswana, with two round diamonds from Princess Diana’s collection. It was made by London jeweller Cleave and Company. The centre stone is estimated at 3 to 4 carats.
The ring
To scale
From above, it covers roughly 1.9× the area of a typical 1 carat round diamond. Drawn from the reported weight and typical proportions for the cut, so treat it as a close estimate.
The story
In their November 2017 engagement interview with the BBC, Prince Harry said: “the main stone itself I sourced from Botswana”. The two smaller diamonds came from his mother’s jewellery collection.
The ring originally sat on a yellow-gold band. In 2019 it was seen on a new band set with small diamonds; reports say the reset was done alongside an eternity ring by Lorraine Schwartz, though that isn’t confirmed.
What it means for you: a three-stone ring is the classic way to include family stones. Many Hatton Garden jewellers will reset diamonds you already own around a new centre stone, which can make a ring both personal and better value.
