Diamond Miner Gem Diamonds has found a 202 carat rough diamond at its Letšeng mine in Lesotho, Sothern Africa. The rough diamond is the latest of seven recovered over 100 carats this year.
The D colour type IIa diamond was recovered when they mine switched to the higher grade K6 section of the main pipe earlier this year.
The Letšeng mine is one of the highest diamond deposits by value in the world with the an average price of $2,397 per carat for the July tender.
De Beers is planning to add the world’s largest custom built diamond mining vessel to its fleet at a cost of $142 million.
The ship will be the sixth belonging to Debmarine Namibia, a 50/50 joint venture between the miner and the Republic of Namibia, De Beers said Tuesday. Expected to begin operations in 2021, it will enhance the company’s ability to recover diamonds off the southern African country’s Atlantic coast, the rough producer added.
“There is a great amount of potential in Namibia’s marine diamond deposits, and this new vessel will support our strategy to continue to grow our offshore operations,” said De Beers CEO Bruce Cleaver.
Earlier this year, De Beers launched the MV SS Nujoma, the world’s largest diamond sampling and exploration vessel. Acquiring the new ship will help the company capitalize on that vessel’s work, and support the long-term future of Namibia’s diamond sector, Cleaver added.
Kleven Verft, a Norwegian ship-building company that constructed the Nujoma, will also build the new vessel, and has signed a memorandum of understanding with De Beers.

Dealers reported a difficult but stable rough market as De Beers’ November sight closed with a value of $455 million — 4% lower than the same period a year ago.
The rough market improved slightly from the October sight, which was the smallest sale of the year as Indian manufacturing slowed for Diwali. However, sightholders still noted weak profitability on De Beers goods during November, with premiums on the secondary market close to zero.
Most boxes of diamonds from last week’s sight commanded prices on the dealer market that did not cover the costs of doing deals, explained Dudu Harari of diamond broker Bluedax in a report on the sight.

The Diamond Mine in Ontario started production in July 2008 will continue to operate until the open pit is exhausted. This is in line with the company’s original study of mine and the plan for the project.

De Beers’ October sight closed with a value of $370 million as rough-diamond buying slowed due to holidays and sightholders reported a sluggish dealer market.
Proceeds from the miner’s eighth sales cycle fell 27% from $507 million in the previous sight in August, and dropped 25% compared with the equivalent period a year ago, according to Rapaport records. Rough prices were largely unchanged from the previous sight, sightholders noted, with many dealers on the secondary market struggling to make a profit on the goods or even cover costs.
De Beers offered fewer rough diamonds for sale during the month as last week’s sight occurred during a period when polishing factories in India and Israel were closed for religious holidays, the company’s CEO Bruce Cleaver explained Tuesday.
“Sales were in line with expectations, at what is a seasonally slower time for rough-diamond demand,” Cleaver added.
The Indian cutting industry is preparing to close for Diwali, which occurs this Thursday. Buyers brought rough purchases forward to the July sales cycle because of the relatively early date of the festival this year, De Beers noted at previous sights. The last two sights have both been significantly smaller than a year ago as a result.
Sightholders were optimistic about the end-of-year holiday season, even as De Beers’ rough sales have declined 7% to $4.38 billion for the year to date, Rapaport records show. Russian miner Alrosa echoed this positive outlook, also noting that the timing of Diwali had weakened sales in September.
“We expect the traditional revival of the market situation in the fourth quarter, as the industry starts to prepare for the winter holiday season,” Alrosa vice president Yury Okoyomov said last week.

A yellow diamond is a coloured diamond characterised by its natural yellow body colour. Yellow must be the predominant colour in the diamond, though it can be modified by other hues, such as green, orange, or brown, which can influence the overall appearance of the stone.
Key Characteristics of Yellow Diamonds
Colour Origin:
The yellow colour in diamonds is primarily caused by the presence of nitrogen atoms within the diamond’s crystal structure. These nitrogen atoms absorb blue light, which results in a yellowish hue. The more nitrogen present, the more intense the yellow colour can become.
This unique characteristic makes yellow diamonds distinct from other coloured diamonds, such as blue diamonds, which gain their colour from the presence of boron.
Colour Variations:
While yellow diamonds are often uniformly yellow, the shade and intensity of the yellow can vary widely. Some may show a subtle, faint yellow, while others exhibit a vibrant, rich yellow that is striking and eye-catching.
The yellow can sometimes be modified by secondary hues. For instance, greenish-yellow diamonds might show a yellow-green tinge, while brownish-yellow diamonds can appear more earthy or muted. These variations in colour can affect the diamond’s overall value and appeal.
Canary Diamonds:
The term “canary diamond” refers to a particularly vivid, intense yellow diamond. These diamonds are much rarer than the more common yellow diamonds, and their colour can range from brilliant lemon yellow to golden hues.
Canary diamonds are highly prized in the market for their bright, vibrant appearance and often fetch higher prices due to their rarity and striking colour.
Rarity and Availability:
Natural yellow diamonds are relatively common compared to some other coloured diamonds, like pink or blue diamonds. However, the intensity and depth of the yellow colour can influence the rarity and desirability of a diamond.
Yellow diamonds are found in several regions around the world, including Africa, Australia, and South America.
Grading Yellow Diamonds:
Like all diamonds, yellow diamonds are graded on a combination of colour, clarity, cut, and carat weight. However, when grading coloured diamonds, the hue, tone, and saturation are the primary focus.
Hue refers to the primary colour of the diamond (in this case, yellow), tone refers to the lightness or darkness of the colour, and saturation measures the intensity of the colour. A high saturation, deep yellow diamond will generally be more valuable than a pale or less saturated one.
The most sought-after yellow diamonds have a vivid yellow hue with high saturation and a pleasing, even colour distribution throughout the stone.
Symbolism and Use:
Yellow diamonds are often associated with happiness, wealth, and success due to their vibrant, sunny appearance. They can also symbolise optimism and joy, making them a popular choice for engagement rings, jewellery, and special gifts.
Due to their striking appearance, yellow diamonds are often used in high-end jewellery, where their bold colour can stand out and create a dramatic effect.
Price and Market Appeal:
The price of yellow diamonds can vary significantly depending on factors like colour intensity, clarity, and size. Vivid yellow diamonds, particularly those with a deep, rich hue, tend to fetch higher prices due to their rarity and the high demand in the luxury market.
However, the relative abundance of yellow diamonds compared to other coloured diamonds like pink or blue means they are often more affordable than rarer varieties.
Yellow diamonds are a beautiful and unique variety of coloured diamonds, with their colour arising from the presence of nitrogen in their crystal structure. While yellow diamonds are relatively common, those with intense yellow hues, such as canary diamonds, are rarer and more valuable. These diamonds are graded based on their hue, tone, and saturation, and are prized for their vivid and radiant appearance. They are a popular choice in fine jewellery, symbolising happiness, wealth, and success, while also offering an affordable yet striking alternative to more expensive coloured diamonds.
