The world may call it an ostentatious display of wealth, but for an Ambani, it is simply an accessory. From a $150 million Cartier necklace to 50-carat diamond earrings worth a staggering $17 million, and now to the latest addition, a 70-carat diamond thumb ring, nothing seems too extravagant for this family with a well-known fondness for spectacular jewels. Then again, this is Isha Ambani, a member of Asia’s richest clan, headed by Mukesh Ambani. The Reliance Industries heiress is increasingly becoming a fashion-forward fixture on the stages that matter most around the world. From art to culture, the Yale graduate is attending them all, sometimes with a $450,000 Hermès Mini Kelly bag in hand and, at other times, with a sparkler such as the whopping 70-carat thumb ring she wore to the Oscars after-party.

Designed by Lorraine Schwartz, the 34-year-old paired the striking piece with high jewelry, including an extraordinary set of 80-carat nude diamond drop earrings. To put that in context, even Elizabeth Taylor’s legendary Krupp Diamond was an Asscher-cut, 33.19-carat diamond ring gifted to her by Richard Burton in 1968. On closer inspection, Ambani’s diamond appears to be a Type IIa stone, a category known for being almost completely flawless and among the rarest in the world. Such diamonds typically sell for around $1.2 million per carat, which means it would be fair to place the ring in the $55 million to $70 million range.

Isha is emerging as a style icon who does not chase fads or trends, but instead leans heavily on stature, legacy, and fashion with purpose. She turned heads not in a Schiaparelli gown, but in a custom Swadesh x Dilara Findikoglu ensemble at the 2026 Vanity Fair Oscars after-party, using the moment to spotlight Indian handloom on a global stage. Celebrating Indian art and artisans is deeply embedded in the Ambani style DNA, and Nita Ambani has done so on several occasions. Isha’s widely admired look featured handwoven Banarasi brocade from the holy Indian city of Varanasi, crafted from mulberry silk and gold threads, and brought together through a gothic corseted silhouette. The highlight, undoubtedly, was the 70-carat diamond thumb ring, a jewel that turned an already memorable look into something truly unforgettable.
