Comprehensive Deep-Dive: King Charles’s Surprising and Symbolic Nickname for Meghan Markle
During the early period following her entry into the British royal family, King Charles bestowed a unique and unconventional private nickname upon Meghan Markle: “Tungsten”.

1. The Meaning Behind “Tungsten”
While comparison to a heavy industrial metal might sound unusual or harsh at first glance, the moniker was initially deployed as a profound compliment.
-
A Symbol of Resilience: Tungsten is renowned in chemistry and physics for having the highest melting point of any known element and extreme structural toughness. Charles used the name to acknowledge Meghan’s formidable inner strength, unyielding character, and remarkable resilience under intense public scrutiny.
-
Providing a Backbone: Insider sources revealed at the time that Charles deeply respected the stability and strength Meghan brought to his younger son. Because he viewed Prince Harry as naturally more sensitive or a “softy,” Charles felt comforted knowing Harry had a partner as unbending and robust as tungsten to help anchor him.

2. A Reflection of Early Warmth and Rapport
The nickname serves as a window into a time when relations between the future King and the Duke and Duchess of Sussex were exceptionally warm.

-
Walking Down the Aisle: This mutual respect was visibly underscored when Charles stepped in to walk Meghan down the aisle at St. George’s Chapel during their May 2018 wedding after her father was unable to attend.
-
Public Praise: In royal author Katie Nicholl’s book The New Royals, accounts detail how Charles frequently praised Meghan’s polished demeanor, sharp intellect, and passion, even referring to her early on as a “breakout star” within the family fold.
3. Shifting Contexts in the Wake of Royal Fallout
As subsequent years brought intense estrangement, institutional conflict, and the Sussexes’ departure from royal duties, public interest in the “Tungsten” moniker has repeatedly resurfaced.
While the nickname began as an affectionate private tribute to her strength, royal commentators frequently note the irony of the descriptor given how fiercely independent and unyielding both Meghan and Harry ultimately proved to be in charting their own course away from the traditional constraints of “The Institution.”
