From historic diamonds to innovative designs, these rings represent the pinnacle of luxury. Here are The 10 Most Expensive Rings that have set records and turned heads this year.
The 10 Most Expensive Rings in the World
1. Wittelsbach-Graff Diamond Ring – $80 Million
The Wittelsbach-Graff Diamond Ring holds the title of the most expensive ring in the world. Featuring a 31.06-carat deep blue diamond, this gem boasts a storied history dating back to the 17th century. Originally part of the Austrian and Bavarian crown jewels, it was acquired and recut by Laurence Graff in 2008, enhancing its clarity and color.
A Storied Past: From Indian Mines to European Royalty
The journey of the Wittelsbach-Graff Diamond begins in the mid-17th century, originating from the Kollur mines in the Guntur District of India, an area famed for producing some of the world’s most exquisite diamonds. Initially weighing 35.56 carats, the diamond’s deep-blue hue and exceptional clarity set it apart. Its early history is somewhat shrouded in mystery, but it is believed to have entered European nobility through the Habsburg family.
In 1722, the diamond became part of the Bavarian Crown Jewels when Maria Amalia of Austria married Karl of Bavaria. It was prominently featured in the Bavarian Elector’s Order of the Golden Fleece and later adorned the Bavarian royal crown. The diamond remained a symbol of Bavarian royalty until the monarchy’s end in 1918, after which it disappeared from public view.
Rediscovery and Transformation
The diamond resurfaced in the mid-20th century, passing through various private collectors before being sold at auction in 2008. Renowned jeweler Laurence Graff acquired the gem for £16.4 million (approximately $23.4 million at the time). Recognizing its potential, Graff made the controversial decision to have the diamond recut to enhance its clarity and color. This process reduced its weight to 31.06 carats but elevated its status, leading to its reclassification by the Gemological Institute of America as an “Internally Flawless Fancy Deep Blue” diamond—the largest of its kind ever graded.
The recutting sparked debate among gemologists and historians, with some criticizing the alteration of a historic gem. However, others acknowledged the improved brilliance and quality achieved through modern cutting techniques.
Current Ownership and Display
In 2011, the diamond was reportedly sold to Sheikh Hamad bin Khalifa Al Thani, the former Emir of Qatar, for a staggering $80 million. While it resides in a private collection, the Wittelsbach-Graff Diamond has been exhibited in prestigious institutions, including the Smithsonian National Museum of Natural History, allowing the public to appreciate its beauty and significance.
Cultural and Scientific Significance
Beyond its monetary value, the Wittelsbach-Graff Diamond holds immense cultural and scientific importance. Its deep-blue color results from trace amounts of boron within its crystal structure, a rarity that offers insights into the geological conditions of diamond formation. The diamond’s transformation also highlights advancements in gem-cutting technology and the evolving standards of gemological assessment.
Impact on the Jewelry Industry
The story of the Wittelsbach-Graff Diamond underscores the dynamic nature of the jewelry industry, where historical artifacts can be reimagined through modern craftsmanship. It reflects a growing trend of blending tradition with innovation, as jewelers seek to enhance the intrinsic qualities of gemstones while honoring their heritage. This approach resonates with contemporary consumers who value both authenticity and excellence.
