Lucara Recovers 470 Carat Diamond from the Karowe Mine in Botswana

    470 carat diamond recovered from the                    Karowe Mine in Botswana

Lucara Diamond Corp. is pleased to announce the recovery of a 470 carat top light
brown clivage diamond from its 100% owned Karowe Diamond Mine located in Botswana.

The diamond, measuring 49x42x26mm, was recovered from direct milling of ore sourced from the EM/PK(S) unit of the
South Lobe. The 470 carat recovery forms a notable contribution to a series of top quality gem and clivage quality
diamond recoveries during a recent production run, including an additional 5 diamonds greater than 100 carats
(265ct, 183ct, 161ct, 116ct, 106ct) and 13 diamonds between 50 and 100 carats in weight.

The May production run, dominated by EM/PK(S) ore, produced diamonds greater than 10.8 carat in weight accounting for 12.7% weight percent of total production, exceeding resource expectations. Continued strong resource performance and recovery of large diamonds reinforces the significance of the EM/PK(S) as an important economic driver for the proposed underground mine at Karowe.


The 470 carat diamond was recovered in the Coarse XRT circuit and represents the third +300 carat diamond
recovered to date in 2021. Year to date, Karowe has produced 10 diamonds greater than 100 carats including 6
diamonds greater than 200 carats, including the 341 carat (link to press release) and 378 carat (link to press release)
top white diamonds recovered in January 2021.

Petra puts “exceptional” 39-carat blue diamond up for sale


    39.34 carat blue diamond recovered by Petra                                         South Africa

South Africa’s Petra Diamonds has put a 39.34 carat Type IIb gem recovered at its iconic Cullinan mine in April up for sale, with viewings beginning June 15.

The company said the diamond of “exceptional quality” in terms of both its colour and clarity, will be showcased in Antwerp, Dubai, Hong Kong and New York.

Petra, which anticipates that the diamond will be sold via a special tender, said that biddings via its online platform will close on July 12.

While it didn’t set a price range for the stone, the miner said high-quality blue diamonds like the one for sale usually fetch the highest values.

Petra’s Blue Moon of Josephine diamond, cut from a 29 carat rough blue diamond, sold for $48.5 million in 2015.

The figure corresponds to a price of $4 million per carat, which remains the world record price per carat ever paid for a diamond.

Cullinan is known as the world’s most important source of blue diamonds, as well as being the birthplace of the 3,106-carat Cullinan diamond, which was cut to form the 530-carat Great Star of Africa. The operation also yielded the 317-carat Second Star of Africa. They are the two largest diamonds in the British Crown Jewels.

73ct. Yellow to Shine at Sotheby’s New York Sale

                            73.11 carat yellow diamond

Sotheby’s will offer a fancy-vivid-yellow diamond ring at its New York sale next month, estimating the piece could fetch up to $3 million.

The cut-cornered square step-cut, 73.11-carat, VS2-clarity jewel by Mayfair designer Glenn Spiro, called The Sienna Star, is one of the largest fancy-vivid-yellow diamonds to come to auction, Sotheby’s said Wednesday. The piece is one of the top items at the June 9 Magnificent Jewels sale. The auction will feature jewelry for the “Roaring Twenties 2.0” as people return to the social scene following long lockdowns, Sotheby’s noted.

A private collection of six jewels with a combined estimate of more than $13 million are another headline lot at the New York sale. Those include a necklace by Andrew Clunn, set with 28 oval-shaped diamonds totaling over 168 carats, which carries a high estimate of $3 million, and an emerald-cut, 23.59-carat, D-color, internally flawless, type IIa diamond ring with an upper valuation of $2.8 million.

A Colombian emerald and diamond garland necklace by Harry Winston, estimated at up to $2.5 million, and a 13.02-carat Burmese ruby ring, mounted by Carvin French, with a $2 million high valuation, are also part of the collection. Proceeds from the sale of those six items will be donated to charity.

Additionally, Sotheby’s will showcase a Bulgari ring with a 25.29-carat Kashmir sapphire flanked by diamonds, which it expects will bring in up to $3 million. Meanwhile, a modified square brilliant-cut, 3.75-carat, fancy-intense-pink, VVS1-clarity diamond ring, accented by triangle-shaped and round diamonds, is estimated to fetch up to $2.5 million.

The auction house will present jewels from the collection of philanthropist Margaret Jonsson Rogers, the daughter of Texas Instruments founder and Dallas mayor J. Erik Jonsson, as well as property from the estate of Mary Ethel Weinmann, the daughter of Count and Countess André de Limur, it added.
