See Meghan Markle’s new diamond ring up close

Meghan Markle’s finally giving fans a close-up look at her new sparkle.

The Duchess of Sussex debuted a mysterious (and massive) pear-shaped diamond ring at the One805LIVE! charity concert last September, and later slipped on the same bauble for the NBA All-Star Game in February.

And on Sunday, the giant rock was front and center in Markle’s latest As Ever Instagram post, stacked with several other bands on her right-hand ring finger.

Rare Carat CEO Ajay Anand told Page Six Style the center stone looks to be around 6 carats.

The duchess often opts for lab-grown diamonds, and Anand’s company sells similar gems for between $5,000 and $6,000.

If Markle’s diamond is natural, however, her new ring would be worth far more — anywhere from $100,000 to half a million dollars, depending on the quality of the stone.

While seemingly not an engagement ring upgrade — the duchess also sported her three-stone sparkler from husband Prince Harry, which features a pair of stones once owned by Princess Diana, at both the benefit concert and the basketball game — it’s possible that this new piece also has a tie to her late mother-in-law.

“My first instinct is that the diamond (or gemstone) could be from Diana’s collection,” What Meghan Wore founder Susan Courter wrote on her site, which chronicles Markle’s wardrobe choices.

“Perhaps it was once part of a necklace, a pair of earrings, or another piece that was later redesigned into a ring. We’ve seen meaningful stones reimagined before, so it wouldn’t be out of the realm of possibility.”
