When Meghan Markle made a surprise appearance during Prince Harry's interview with James Corden on The Late Late Show she looked happy and relaxed in a £21 summer dress.
However, eagle-eyed fans also noticed that the Duchess of Sussex – who was shown on camera via a video call – had accessorised with a stunning blue gemstone necklace.
It has been revealed that the pretty piece of jewellery costs £1,029.78 from a collection of "wearable talismans" created by US fitness brand The Class, which was founded by her friend Taryn Toomey.
Prince Harry's wife opted for the Trapezoid Necklace In Lapis – and it comes with an inspiring hidden meaning.
According to The Class' website, this particular gemstone – also known as lapis lazuli – "aids in self-expression and revelation of one's inner truth".
The company adds that it is "widely regarded as a token of sincerity and wisdom – and is especially helpful to anyone in need of a boost in self-confidence and a stronger connection to their inner voice".
The necklace is from the brand's 'The Airelume' range, which features pieces that act as "reminders of one's infinite truth".
They are designed onto a 14k yellow gold chain, and are handmade in New York, with other gemstones enlisted including labradorite and tourmaline.
Toomey – a former executive for Ralph Lauren and Dior – founded The Class in 2013 after training to become a yoga teacher and studying with a shamanic healer.
Jennifer Aniston, Christy Turlington, and Gisele Bundchen are fans of the brand's classes, which it describes as a "cathartic workout experience that guides you to strengthen the body and notice the mind to restore balance".
The duchess – who is pregnant with her second child, a daughter – wore the necklace shortly before speaking to Oprah Winfrey in an interview in early March in which she said she felt "liberated" to be "able to speak for myself".
It has a stretchy "smocked bodice" – making it ideal maternity-wear for a growing bump – and it also features a scoop neck and elbow-length puff sleeves.
What's more, it is designed to slip on over the head, without any faffing with zip or button fastenings – perfect for busy mornings as a parent when the weather heats up.
During her chat with Corden, the duchess jokily responded to the suggestion her young family should move into the real-life The Fresh Prince Of Bel-Air house, which is located in the Brentwood area of Los Angeles.
Laughing, the mother-of-one said: "That's wonderful, [but] I think we've done enough moving!"
