Meghan and Prince Harry made a surprise cameo in Spotify's Stream On event on Monday, marking their first appearance since announcing that they are expecting their second child.

For more on Prince Harry and Meghan Markle, listen below to the episode of PEOPLE Every Day! She sported the $1,144 Pink Sapphire Cocktail Ring With Diamond Pavé by Ecksand, a Canadian jewelry brand.

The ring features an ethically-sourced rose cut pink sapphire set into a 100% recycled gold band with diamond pave, touching on another important issue for Meghan: sustainable style. "Not only are we excited for the Archewell Audio podcast, we are incredibly honoured that Meghan chose to re-wear one of our sustainable jewels during her first public appearance since announcing her pregnancy," said Erica Bianchini, Co-Founder and Creative Director of Ecksand. "Our commitment to sustainable practices is something Meghan connects with. That's a cause that Harry and Meghan hold close to their hearts."
