“Gem Diamonds also unearthed an 80 carat stone and another 79 carat diamond from Letseng on the same day.”
Few things are more dazzling and impressive than a large, glistening diamond. The valuable gems are one of the most beautiful and labor-intensive gifts from Mother Nature.
Of course, the larger ones weighing 100 carats or more are even rarer and more special.
If 2019 was a year of transition and growing pains for the diamond sector, 2020 is expected to bring collaboration and growth. It is shaping up to be a profitable period for diamond miners with the recovery of a slew of stones, including yet another large diamond weighing more than 100 carats.
Given the recent activity in the diamond space, we have compiled a list of 2020’s largest finds to date. Read on to learn more about them and stay tuned for new additions to the list.
1. Lucara Diamond’s 549 and 176 carat diamonds from Botswana

The year’s most recent discovery is also the largest gem of 2020 to date. In early February, Lucara Diamond (TSX:LUC,OTC Pink:LUCRF) recovered a 549 carat white diamond of “exceptional quality” from its Karowe mine in Botswana. The exquisitely rare find came as a result of the company’s Mega Diamond Recovery XRT circuit, which allows for diamond recovery after primary crushing and prior to milling.
The integration of technology to allow for the retrieval of larger stones is helping the sector rescue big diamonds that may have been crushed or broken in the past.
“New recovery technologies, including X-ray transmission, have resulted in less breakage of the largest stones in recent years. However, the recovery of these diamonds is still extremely rare on a relative basis,” diamond analyst Paul Zimnisky told the Investing News Network.
Lucara’s 549 carat diamond was captured from the same ore block that produced a 176 carat diamond earlier this year. The gem-quality stone and the 500+ carat white diamond are among four other 100+ carat diamonds the miner has already unearthed since the beginning of the year, with the most recent two being the most valuable.
“Lucara is extremely pleased to be starting off 2020 with the recovery of two, large, high quality diamonds that builds on the positive momentum generated following the completion of a strong fourth quarter sale in December and the announcement of our ground breaking partnership with Louis Vuitton on the Sewelô in January,” said Lucara CEO Eira Thomas.
2. Gem Diamonds’ 183 carat diamond from Lesotho

In early February, Africa-focused miner Gem Diamonds (LSE:GEMD) discovered a 183 carat stone. The jewel is a type IIa diamond, the purest and highest valued of the classifications.
The diamond was discovered at the company’s renowned Letseng mine in Lesotho. Letseng is a large open-pit mine that has produced some of the largest diamonds ever, including the 910 carat Lesotho Legend, the 603 carat Lesotho Promise and the 550 carat Letseng Star.
Gem Diamonds also unearthed an 80 carat stone and another 79 carat diamond from Letseng on the same day. These smaller diamonds are described as high quality as well.

While all large recoveries are impressive, they are certainly not all of the same quality. Type IIa stones, colored gems and naturally shaped high-quality diamonds are all more valuable than an extremely large, low-quality stone.
“I estimate that there have been less than 20 gem-quality diamonds that are in excess of 100 carats recovered per year on average over the last five years,” said Zimnisky.
This extreme rarity only adds to the mystery and allure that diamonds possess.
3. Lucapa Diamond’s 117 carat diamond from Angola

2020’s large diamond haul was kicked off on the ninth day of the year when Australia’s Lucapa Diamond (ASX:LOM) recovered a 117 carat gem-quality stone from its Lulo mine in Angola.
Commenting on the company’s latest discovery, Managing Director Stephen Wetherall announced, “The recovery of this gem-quality 117 carat diamond represents a positive start for Lulo in 2020 as we continue rolling out our plans to increase production and revenues this year.”
The area where the miner unearthed the gem — mining block 19 — has been fruitful. Adjacent blocks 6 and 8 have produced a dozen 100+ carat gems, including the largest diamond ever mined in Angola, the 404 carat 4th February diamond, which sold for US$16 million in 2016.
