The Moussaieff Red Diamond was displayed as part of the eight most incredible diamonds in the world, thus, magnifying its prominence in the diamond industry.


Blue diamonds represent only 1% of all minedfancy colored diamonds. The Heart of Eternity, a fancy vivid blue, was mined in the South African Premier Diamond Mine. An exceptionally rare diamond thanks to its lack of gray or black undertones, this stunning heart shaped stone was originally cut from a 777ct rough diamond.

The original owner of The Heart of Eternity was the Steinmetz Group, but De Beers later bought it in 2000. Rumour has it that in 2012 boxer Floyd Mayweather purchased the diamond for then-fiancée, Shantel Jackson. This has not however been confirmed by De Beers.


In 2010, Christie’s sold The Perfect Pink to an unknown bidder. This Fancy Intense Pink is a 14.23 ct emerald cut diamond. What makes this gemstone so rare is both its size and intensity of pink. It has a clarity grade of Very Very Slightly Included 2 (VVS2) due to slight internal blemishes, which is common in diamonds such as The Perfect Pink.

Mined in South Africa in 1999, the Pink Star, previously known as the Steinmetz Pink, is the largest diamond to have been graded a Fancy Vivid Pink. Chow Tai Fook Enterprises, a Hong Kong, bought the Pink Star from Sotheby’s auction in 2017 in a telephone bid. An internally flawless, oval diamond weighing a huge 59.60ct, this gemstone was later renamed to CTF Pink Star in memory of the current Chow Tai Fook chairman’s late father.


As a rough diamond, the Centenary Diamond weighed over 500ct. It was later cut to a modified heart-shape, weighing 273.85ct.

It took a total of 154 days for their highly-skilled team to finish the re-cutting process.


Believed to have been discovered in India in the 1600s, the Hope Diamond was bought by King Louis XIV in 1668. This 45.52 carat Fancy Dark Gray-Blue antique cushion cut diamond was later stolen during a crown jewel looting in 1791 but resurfaced in London in 1839. Fast forward to 1949, Harry Winston purchased this diamond and donated it to the Smithsonian Institution, attracting many tourists. The stone is rumored to be cursed due to the misfortune and tragedy that many of its previous owners experienced.


The Cullinan is the largest rough diamond of gem quality ever found, weighing an incredible 3,106.75ct . Discovered in Cullinan, South Africa in 1905, it was then gifted to King Edward VII.

Topping our list of the most expensive diamonds in the world is the legendary Koh-I-Noor. Weighing in at a massive 105.6ct, the most expensive diamond in the world is oval shaped. Steeped in mystery and legend, the stone is believed to have been mined in India in the 1300s.

The controversy behind the stone lies in claims that Britain stole the stone from India and that it rightfully belongs to India. Rightly or wrongly, Britain acquired the stone in 1850 and in 1852, Prince Albert had it cut from 186ct to 105.6ct to increase its brilliance andsparkle. The colorless oval-cut diamond is also known as Mountain of Light and the Diamond of Babur.
