A ring fit for royalty! Charlotte Casiraghi, granddaughter of Hollywood royalty Grace Kelly and eighth in line for Monaco’s throne, flashed an impressive engagement ring while attending the 2018 Rose Ball this past weekend, leading royal fans to get giddy about another royal wedding this year.

Casiraghi, 31, and her now-fiancé, film producer Dimitri Rassam, reportedly got engaged three weeks ago while on vacation together in Austria, but the fashion muse first debuted her stunning ring on Saturday at the gala in Monte Carlo.

Casiraghi donned a head-turning, feathered black-and-white dress by Saint Laurent by Anthony Vaccarello for the event (and wore no jewelry aside from the oversized ring!), while Rassam, 36, wore a simple black suit by the same designer.

Though neither side has yet publicly confirmed the details of the bling, eagle-eyed social media users are surmising that it appears to consist of a diamond solitaire set in yellow gold.

The pair first confirmed their relationship in March of last year after meeting through mutual friends back in 2016, and the royal wedding is reportedly set to take place this coming July, possibly in Sicily, where Rassam’s mother, actress Carole Bouquet, owns a 20-acre vineyard.

Both Casiraghi and Rassam will be marrying more than each other, however; the pair are both already parents from previous relationships, and would be joining their families together in holy matrimony. Casiraghi has a 4-year-old son Raphael with her ex Gad Elmaleh, and Rassam has a daughter from a previous marriage.

Casiraghi and Rassam’s wedding would mark another major milestone for the royal family this year: Meghan Markle and Prince Harry are due to be married at Windsor Castle in May and Princess Eugenie, who announced her engagement to longtime boyfriend Jack Brooksbank this past January, will get married in October.
