The Queen gave Meghan the earrings she wore on Wednesday on June 14, 2018, shortly before they both attended an official engagement in Halton, England.
Meghan described this moment in her interview with Oprah Winfrey last year. The Duchess of Sussex said that she and the Queen were traveling to the engagement by train when the monarch gifted her “beautiful pearl earrings and a matching necklace.”
“We had breakfast together that morning, and she’d given me a beautiful gift. I just really love being in her company,” Meghan said.
