The 59.60-carat diamond, worth more than $60 million, will be auctioned off at [Sotheby’s](https://money.com/sothebys-most-expensive-picasso/) “Magnificent Jewels and Jadeite Spring Sale” in Hong Kong. It’s the largest "Internally Flawless, Fancy Vivid Pink" diamond ever to be graded by the Geological Institute of America (GIA), Sotheby’s [said](http://www.sothebys.com/en/news-video/videos/2017/the-pink-star-a-true-masterpiece-of-nature.html). The diamond fits onto a ring. One jewelry expert — Tobias Kormind of 77 million, an online diamond seller — expects the “Pink Star” to go for more than $100 million, [CNN reported](http://money.cnn.com/2017/04/04/luxury/pink-star-diamond-auction-sothebys/index.html?iid=hp-stack-dom) Cutting the diamond took nearly two years to complete. The diamond was first auctioned off by Sotheby’s in Geneva in 2013, where it [sold for a record](http://www.bbc.com/news/business-24934297) $83 million to New York-based diamond cutter Isaac Wolf. He ended up defaulting on the deal, CNN reported. By bringing the diamond to Hong Kong, Sotheby’s is “writing a new chapter in its story by offering it for sale in Hong Kong, now a global epicenter for the world’s wealthy,” Kormind told CNN. ```json { "@context": "https://schema.org", "@graph": [ { "@type": "BreadcrumbList", "@id": "https://money.com/rare-59-carat-diamond-expensive-sothebys-auction-hong-kong-pink-star/#breadcrumb", "itemListElement": [ { "@type": "ListItem", "position": 1, "name": "Home", "item": "https://money.com" }, { "@type": "ListItem", "position": 2, "name": "Lifestyle", "item": "https://money.com/lifestyle/" }, { "@type": "ListItem", "position": 3, "name": "Art and Culture", "item": "https://money.com/art-and-culture/" }, { "@type": "ListItem", "position": 4, "name": "This Rare 59-Carat Gem Could Become The Most Expensive Diamond Ever Sold at Auction" } ] }, { "@type": "WebSite", "@id": "https://money.com/#website", "url": "https://money.com", "name": "Money", "publisher": { "@id": "https://money.com/#organization" } }, { "@type": "WebPage", "@id": "https://money.com/rare-59-carat-diamond-expensive-sothebys-auction-hong-kong-pink-star/#webpage", "url": "https://money.com/rare-59-carat-diamond-expensive-sothebys-auction-hong-kong-pink-star/", "name": "This Rare 59-Carat Gem Could Become The Most Expensive Diamond Ever Sold at Auction", "isPartOf": { "@id": "https://money.com/#website" }, "datePublished": "2017-04-04T12:00:06.000Z", "mainEntity": { "@id": "https://money.com/rare-59-carat-diamond-expensive-sothebys-auction-hong-kong-pink-star/" }, "inLanguage": "en-US", "breadcrumb": { "@id": "https://money.com/rare-59-carat-diamond-expensive-sothebys-auction-hong-kong-pink-star/#breadcrumb" }, "dateModified": "2024-04-17T05:34:54.000Z" }, { "@type": "Article", "headline": "This Rare 59-Carat Gem Could Become The Most Expensive Diamond Ever Sold at Auction", "articleSection": "Lifestyle", "image": [ { "@type": "ImageObject", "url": "https://img.money.com/2017/04/pink-star-diamond.jpg", "width": 5000, "height": 3168, "caption": "The Pink Star Diamond goes on auction with Sotheby's Hong Kong" } ], "author": [ { "@type": "Person", "name": "Jennifer Calfas", "url": "https://money.com/author/jennifer-calfas/", "@id": "https://money.com/author/jennifer-calfas/#author", "sameAs": [ "https://x.com/jencalfas" ] } ], "publisher": "https://money.com/#organization", "datePublished": "2017-04-04T12:00:06.000Z", "description": "The 59-carat Pink Star diamond is expected to become the most expensive diamond ever sold at an auction", "abstract": "The 59-carat Pink Star diamond is expected to become the most expensive diamond ever sold at an auction", "@id": "https://money.com/rare-59-carat-diamond-expensive-sothebys-auction-hong-kong-pink-star/", "inLanguage": "en-US", "dateModified": "2024-04-17T05:34:54.000Z", "wordCount": 180, "keywords": [ "luxury", "onetime" ], "about": [ { "@type": "Thing", "name": "Lifestyle", "sameAs": [ "https://en.wikipedia.org/wiki/Lifestyle" ] }, { "@type": "Thing", "name": "Contents/Culture and the arts", "sameAs": [ "https://en.wikipedia.org/wiki/Wikipedia:Contents/Culture_and_the_arts" ] } ] } ] } ```
