According to historical records the Hope Diamond first appeared in India during the 1600s before King Louis XIV purchased it in 1668.

The Koh-I-Noor — Unknown

Among all diamonds in the world the legendary Koh-I-Noor stands as the most expensive gemstone. The most expensive diamond exists as an oval stone which encompasses 105.6 carats in total weight.

The popular rough diamond was found in 2019 by Lucara Diamond Corp a Canada based diamond mining company at its Karowe operation. The 1,758-carat rough diamond was about as big as a tennis ball. First, it seemed to be black since it was coated with a thin layer of black carbon. This meant that it was only possible to assess the quality of diamond, by cutting through it as a means of getting acquainted with the kind of diamond the client wanted. 

#3. Lesedi La Rona Diamond

Nine employees of Lucara discovered this 1,109-carat, colorless diamond in 2015 at its Karowe mine. When found it was the biggest diamond discovered in over a century, and only second to the Cullinan diamond. It was bought by Laurence Graff in 2017 for $53m for his jewelry house brand GRAFF, and it took gemologists of the company several months to examine the diamond before they began to cut it. Because the diamond was too large to fit in the company’s existing scanning equipment and software, Graff’s technicians required new ones. 

#4. Lucara Diamond

The Karowe mine saw Lucara discover its namesake diamond in the year 2021. It has a dimension of 77mm by 55mm by 33mm but it is not a 100 % gem quality diamond. In its stead, the company refers to it as a clivage gem of variable quality that has large areas of high quality white gem material.

Miners stumbled on it on February 14, 1972 at the Diminico alluvial mine in the Koidu region of Sierra Leone. 

#9. Lesotho Legend Diamond

#13. Golden Jubilee Diamond

The Golden Jubilee was discovered in 1985 in the Premier mine, South Africa by the De Beers workers, the same mine as that of Cullinan origin. It settled for hiring Gabriel Tokowsky to chop 755.

The thing was, the diamond was not of the usual round shape at the beginning.

#15. Peace Diamond

Of all the stones in our top 15, the Peace Diamond stands out as the luckiest find of them all.
