what is the most expensive diamond in the world

The most expensive diamond publicly sold in the world so far is the Pink Star diamond, a 59.60-carat fancy vivid pink, internally flawless stone that sold for about 71.2 million USD at auction in Hong Kong.

What Is the Pink Star Diamond?

• The Pink Star is a 59.60-carat, fancy vivid pink, internally flawless diamond, one of the largest and highest-quality pink diamonds ever graded.

• It was originally a 132.5-carat rough stone mined by De Beers in Africa and took over two years to cut and polish into its current oval shape.

Record-Breaking Price

• At a Sotheby’s auction in Hong Kong, the Pink Star sold for about 71.1–71.2 million USD, setting the record for the highest price ever paid for a diamond at auction.

• This price also makes it one of the most expensive pieces of jewelry ever sold, not just the most expensive diamond.

Other Ultra-Expensive Diamonds (For Context)

• The De Beers Centenary Diamond is often valued around 100 million USD on paper, but it has not been sold at public auction, so its price is an estimate rather than a confirmed sale.

• Other record-setting diamonds include the Graff Pink and various blue and pink diamonds that have sold in the tens of millions, but none have surpassed the Pink Star’s confirmed auction price.

Why It’s So Valuable

• Pink diamonds are among the rarest colored diamonds; large stones with vivid color and top-tier clarity are exceptionally scarce.

• The combination of carat weight, color intensity, internally flawless clarity, and a high-profile auction in a major luxury market helped push the Pink Star to its record price.
