Meghan Markle wears constellation necklaces for Archie and Lilibet

Meghan Markle’s two children are the real stars in her life.

The Duchess of Sussex marked her 40th birthday on Wednesday by sharing a special video message on her and Prince Harry’s Archewell website announcing her new 40×40 mentorship program.

And for her first public appearance since giving birth to daughter Lilibet in June, she wore two diamond-studded jewelry pieces with sweet family ties.

Megan layered Logan Hollowell’s Taurus Constellation Necklace ($1,600) — a nod to 2-year-old son Archie’s astrological sign — with the Gemini Constellation Necklace ($1,785), in honor of 2-month-old Lili’s.

The LA jeweler uses recycled gold and ethically sourced gemstones in her work, making her delicate pieces an ideal pick for the sustainability-focused Duchess.

Megan’s got plenty of other sentimental gems in her collection, including a diamond eternity band featuring her birthstone alongside Harry’s and Archie’s. She’s also been spotted wearing a tiny gold “A” pendant in her son’s honor, as well as zodiac necklaces adorned with Virgo and Taurus charms for Harry and Archie, respectively.

She’s also the proud owner of several of her late mother-in-law Princess Diana’s precious pieces — among them the aquamarine ring she wore for her wedding reception in 2018, a pair of pretty butterfly earrings and the diamond tennis bracelet she chose for her bombshell interview with Oprah Winfrey in March.
