Top 5 Most Expensive Diamonds

While all diamonds are extracted from the ground, they are not all made equal. Diamonds have captivated gemologists and proceeded to break price records throughout the years. So, which diamonds are the most valuable? We've compiled a list of the top 5 most valuable diamonds ever.

  1. The Koh-i-Noor (Unknown)

    The famous Koh-I-Noor is at the top of our list of the world's most valuable diamonds. The world's most valuable diamond, weighing in at a whopping 105.6 carats, is oval in shape. The stone, which is shrouded in mystery and folklore, is said to have been mined in India in the 1300s. The stone was purchased by the United Kingdom in 1850, and Prince Albert had it cut from 186ct to 105.6ct in 1852 to improve its brightness and glitter. Mountain of Light and the Diamond of Babur are two names for the colorless oval-cut diamond.

  2. The Cullinan (up to $2 Billion)

    The Cullinan is the world's biggest gem-quality rough diamond, weighing an astounding 3,106.75ct. In 1905, it was discovered in Cullinan, South Africa, and given to King Edward VII. The Star of Africa raw diamond was cut into nine major stones, the biggest of which is the 530.2ct Cullinan I.

  3. The Hope Diamond ($200-250 Million)

    The Hope Diamond, thought to have been found in India in the 1600s, was purchased by King Louis XIV in 1668. This 45.52 carat Fancy Dark Gray-Blue ancient cushion cut diamond was taken in 1791 during a crown jewels theft, but it was subsequently discovered in London in 1839. In 1949, Harry Winston bought the diamond and gave it to the Smithsonian Institution, drawing a large number of tourists. Due to the misery and tragedy that many of its former owners have endured, the stone is said to be cursed.

  4. The Centenary Diamond ($100 Million)

    The Centenary Diamond weighed more than 500 carats as a raw diamond. It was eventually reshaped into a modified heart form and weighed 273.85ct. The reduction in carat weight, on the other hand, increased the color (D) and clarity (flawless) of this one-of-a-kind diamond. It took their highly-skilled staff 154 days to complete the re-cutting procedure.

  5. The Pink Star ($71.2 Million)

    The Pink Star, formerly known as the Steinmetz Pink, was discovered in South Africa in 1999 and is the world's biggest Fancy Vivid Pink diamond. In 2017, Hong Kong-based Chow Tai Fook Enterprises won the Pink Star at a Sotheby's auction through a telephone bid. CTF Pink Star was dubbed after the current Chow Tai Fook chairman's late father. It was an internally perfect oval diamond weighing a massive 59.60ct.
