London-based miner Gem Diamonds has announced the recovery of an exceptional quality 149 carat, D color Type IIa diamond, with excellent shape, from the Letšeng mine in Lesotho, the highest dollar per carat kimberlite diamond mine in the world. This is the fourth high quality diamond of over 100 carats recovered so far this year, and follows closely upon the recovery of the exceptional 910 carat diamond announced on 15 January, 2018.
Investors are taking notice, as the company's stock price on the London Stock Exchange has surged approximately 25% over the past month. The London-based company recovered seven such stones in 2017 after unearthing only five in 2016, and has now nearly duplicated that result in the first month of 2018 alone. The 910-carat diamond, the largest recovered from the Lesotho-based mine, is believed to be the fifth largest gem quality diamond ever recovered.
