Meghan Markle wore a new ring during her most recent appearance, which fans believe could have been a gift from Prince Harry.
The Duchess of Sussex wore the sparkler on her right hand during a surprise joint appearance at Kevin Costner's starry gathering in Santa Barbara last weekend.
Some of her favourite bracelets complemented the pear-shaped ring at the One805LIVE! concert, which took place at Mr Costner's oceanside estate.
The "Queen" ring is estimated to cost £3,185 from the brand Logan Hollowell, and was potentially gifted just in time for Meghan's 44th birthday on August 4.

The ring comes in three sizes - Micro Queen, Baby Queen and Classic Queen.
It is understood that Meghan was wearing the latter, which is the biggest size available.
According to the product description, the central "moonstone" brings "good fortune, success in love as well as business matters".
Sussex fans believe the ring may have been gifted by Prince Harry, as the description contains a nod to the late Diana, Princess of Wales.

It says: "The moonstone is associated with the moon and was the stone of the goddess Diana.
"The most powerful time to use the moonstone is in a full moon."
The ring contains 14k gold, and the pear-shaped gem is surrounded by a halo of white diamonds totalling 0.25 carat weight.
Meghan's new sparkler is available in yellow, rose, or white gold.
