45-carat diamonds are an ultra-large gemstone category with an estimated value ranging from 50 to 60 million USD (about 1,200 to 1,500 billion VND), usually appearing only in private auctions or national museums. With diameters reaching 22 - 25mm, these diamonds are considered humanity's heritage, most notably the legendary "Hope Diamond." Let's join Jemmia Diamond to explore why this diamond possesses such an "entire fortune" price tag.
How much does a 45-carat diamond cost?
The current price of a 45-carat diamond ranges from about 1,200 billion VND to over 1,500 billion VND (50 – 60 million USD), depending strictly on GIA's 4Cs standards. This is the price level for stones of perfect quality.
To extract a rough diamond large enough to cut into a finished 45-carat gem, millions of tons of earth and rock must be excavated, making it one of the rarest assets. The appeal of a 45-carat diamond lies in:
- Rarity: The chance of finding a diamond of this size is 1 in millions.
- Progressive value: Unlike gold, diamond prices increase exponentially as weight (Carat) rises. A 45-carat diamond is worth thousands of times more than 45 combined 1-carat diamonds.
- Status symbol: Owning this stone means holding a "national treasure," affirming the owner's unrivaled class.

Famous 45-carat diamond masterpieces associated with celebrities
Around the world, 45-carat diamonds are not only jewelry but also historical treasures associated with dynasties and the most powerful figures. With their enormous size, these stones are often crafted into pendants or unprecedented engagement rings:
- Hope Diamond (45.52 Carats) – A treasure of the American elite: This is the most famous blue diamond on the planet. Before being donated to the Smithsonian Museum, it belonged to billionaire Evalyn Walsh McLean. She frequently wore this diamond to lavish parties in Washington, and even attached it to a collar for her pet dog.
- Taylor-Burton Diamond (69-carat ring version): Although this stone weighed nearly 70 carats, its story is the clearest proof of the allure of large diamonds. Actress Elizabeth Taylor was initially given this stone in the form of a ring. However, because it was too heavy and massive to wear on her finger, she asked Cartier to redesign it into a diamond necklace worth 80,000 USD at the time to cover a scar on her neck.
- Rarity in Hollywood: Top stars like Mariah Carey and Beyoncé only own engagement rings from 24 to 35 carats (worth about 5 - 10 million USD). This shows that a diamond reaching the 45-carat threshold is a major leap in rarity and value, far exceeding the jewelry standard of most entertainment superstars today.
