A fantastic 404-carat diamond was just found in Angola. This is the world's 27th biggest diamond that could be worth $14.3 million or A$20 million.

NBC New York has informed that the diamond was unearthed by miners from the Lucapa Diamond Company of Australia, in association with Endiama, Angola's national diamond company and the privately owned Rosas e Petalas.

Lucapa is one of the global top diamond producers. The company has announced that the amazing precious stone is 7 cm long, and is the largest to be discovered in Angola. Before it, a 217.4 carats diamond was found in 2007 in Angola, and was called as the "Angola Star."   

Yehuda, a diamond retailer based in New York examined the spectacular diamond, according to CNN. Lucapa has mentioned that it is tested from its color and clarity, and classified as a Type lla stone, which means it is almost perfect.

The most extraordinary thing from the diamond is the D-colored, or nearly without color, Lucapa added. According to the Gemological Institute of America, this color grade is what makes white diamond the most valuable. In 2015, the Lulo Diamond Project started the exploration of a 1,148 square-mile plot of area. The company confirmed that it has so far delivered more than 60 special diamonds in large sizes.

Lucapa is a smaller diamond exploration company with the symbol LOM on Australia's ASX stock exchange. Before the phenomenal diamond finding was announced, the company had suspended trading for several days. When it started trading again on Monday, the shares hiked to 30 percent. The diamond value of A$20 million had been confirmed by Chairman Miles Kennedy.  

It has been known that Angola is the fourth greatest nation in the world to produce diamond. While this Angolan diamond is the 27th biggest diamond in the world, in the first position is the "Cullinan", a huge diamond in 3,106 carat pearl. It weighed 1.3 pounds and was discovered in 1905 in South Africa. It was now displayed at the Tower of London.  

Yahoo News Australia cited Stephen Watherall, Lucapa Diamond Company chief executive, "We have always emphasized the very special nature of the Lulo diamond field and this recovery - together with the other 100 carat-plus diamonds recovered this year alone - is further evidence of that. And while we continue mining these exceptional alluvial gems from mining blocks 6 and 8 at Lulo, we are also continuing to advance our systematic exploration program to find the kimberlite source of these diamonds."

It is no doubt that Angola is one of those countries, which have produced the biggest diamonds in the world. The 404 carat diamond news has positively increased the company's share. The diamond is spectacular not only for its size, but also for the quality, which has been proven to be very rare and valuable in the world.
