Well this sparkler might break your finger, because it is quite bigger than you think. A massive 404 carat sparkler was unearthed in the southern African country of Angola on Monday.

An Australian company Lucapa Diamond discovered the precious. It is the biggest ever diamond found in Angola and the 27th biggest diamond discovered in the world, according to a report by The Sydney Morning Herald.

The diamond was discovered in the Lulo Diamond Project Mine in Angola’s Lunda Norte province. The mine reports 75% of Angola’s annual diamond production, says Lucapa.

The company claimed that Angola is among the top four countries of the world producing diamonds.

Lucapa Chairman Miles Kennedy, said that it is one of the biggest achievements in the industry.

“When we first looked at the property, 3,000 square kilometres of untouched ground, 700 kilometres inland from the coast, you are talking about a very, very remote area.” said Kennedy.

“The results today are a wonderful vindication of eight years of pretty hard work.

“It’s the biggest diamond ever recorded from the country of Angola and it’s the biggest diamond ever recovered by an Australian diamond miner.”

“So, we have hit a number of firsts finding this diamond.”

According to Australian Broadcasting Corporation, the diamond could be valued at over $20 million.

“We’re not used to valuing 400-carat diamonds, but if we look at other diamonds slightly less weight than this, you’re looking in the order of $20 million” he added.

In early 1990s, Myles Kennedy setup the Ellendale diamond mine in Western Australia’s Kimberley. He later moved to Angola with his geology team and set up Lucapa.

He said during 14 years in Ellendale they only found  one diamond greater than 10.8 carat known as a special diamond.

“With this company in Angola, we have now found over 100 of these special diamonds in the last six months.” he said.

Lucapa’s shares increased by 29 percent after the announcement on Monday.
