Rare Blue Diamond found in South Africa's Cullinan mine
01.22.2014 - bbcnews
A rare blue diamond has been discovered in a mine in South Africa. The 29.6-carat stone was recovered by Petra Diamonds at its Cullinan mine, about 40km (25 miles) north-east of Pretoria. "This stone is one of the most exceptional stones recovered at Cullinan during Petra's operation of the mine," the company said. Petra unearthed a 25.5 carat blue diamond which sold for $16.9m (£10.3m) in 2013. "The stone is an outstanding vivid blue with extraordinary saturation, tone and clarity, and has the potential to yield a polished stone of great value and importance," Petra said in a statement on Tuesday. Cullinan mine has produced hundreds of large stones and is famed for its production of blue diamonds - among the rarest and most highly coveted of all diamonds. The mine was acquired in 2008 by Petra Diamonds, which also operates in Botswana and Tanzania. A similar 26.6-carat blue rough diamond discovered by the company in May 2009 was cut into a near perfect stone and fetched just under $10m at a Sotheby's auction. Another deep-blue diamond from Cullinan was auctioned for $10.8m in 2012 and set a world record for the value per carat. The largest ever rough gem diamond was discovered at the Cullinan mine in 1905 and was presented to the British monarch Edward VII. The 3,106-carat stone was then cut, with two of the principal diamonds forming part of the British crown jewels - the 530-carat First Star of Africa and the Second Star of Africa at 317 carats.

Zimbabwe’s New Diamond Discovery Could Help Struggling Miners
01.14.2014 - rin

The Africa Report said yesterday that Zimbabwe expects to gain billions of dollars from mining new diamonds fields “almost the size of Swaziland.” That’s good news for the African nation, which about a month ago received news that its Chiadzwa diamond fields are becoming less viable to mine. As quoted in the market news: Deputy Mines minister Fred Moyo told state media that the diamond fields located between Manicaland and Masvingo province stretch over 10,000 square kilometres. He said the government has already begun sourcing funds to kick start operations ‘It is a very huge area. So, obviously the whole area cannot contain a large concentration of diamonds, but the fact is there is huge potential,’ Moyo said. ‘What we need to do is mobilise funds to carry out extensive exploration that will determine the areas profitable to mine. ‘We are actually going to use part of our national budget allocation to send our experts to carry out exploration activities in the area.

Diamond Rings Now Available As Wedding Rentals
01.07.2014 - Israelidiamond
As economic recessions take effect in recent years, more and more middle-class people are finding it hard to maintain the same standard of living that their parents were accustomed to. In such a situation, people will look for ways to cut down on costs. But at the same time, some things remain sacrosanct, and no matter how difficult things get, people will continue to pay for items with great sentimental value, such as wedding rings. Now a new threshold seems to have been breached, with a Mexican resort offering even those for rental, PRweb reports. At the Casa Velas boutique hotel in Puerto Vallarta, a popular tourist destination, guests are able to rent polished diamond wedding rings up to eight carats in weight. The rentals runs from $200 for the night at the low end, up to $10,000 for the biggest rocks, and need to be reserved 48 hours in advance. In coordination with Diamonds International, Casa Velas also offers diamond rings for sale, as well as necklaces and bracelets with diamonds and other precious gems, according to PRweb.
Lucapa Diamond unearths 32.2 carat rock from Angola mine
01.03.2014 - miningcom
Shares of Australian Lucapa Diamond (ASX:LOM) were momentarily halted Friday morning as the Australian Stock Exchange was waiting for a formal update on the recovery of a 32.2-carat white diamond from its Lulo mine, in Angola. Later in the day the firm announced it had recovered the D colour massive diamond from a bulk sample approximately 1,600 metres south east of the priority Se251 kimberlite pipe. A D colour is given to only the finest white diamonds; these are totally colourless and classified as “exceptional white”.

The diamond measures 32x10x8mm, is of irregular dodecahedral shape, is the largest recovered through Lucapa's new Dense Media Separation plant, and the fourth largest diamond recovered at Lulo to date.

While the diamond appears flawless to Lucapa staff, this will need to be confirmed by independent examination. Lulo, a joint venture between Lucapa and the Angolan government, hosts type-2a diamonds, which the company qualifies as "the world's rarest and most valuable gems". These kinds of precious rock account for less than 1% of global supply and, according to Lucapa, the world's most famous large, white, flawless diamonds belong to this category.
RUSSIA: What’s Ahead for 2014
01.01.2014 - diamondsnet
The market is optimistic that at the least 2014 will not be a worse year than 2013, which saw both prices and demand fluctuating through the year, before ending on a downward trend. The hope is that the situation in 2014 will at least be stable. ALROSA, Russia’s largest diamond miner, ended 2013 with the same prices it was charging at the end of 2012. By May 2013, its rough prices were up by 6 percent, but the company had to lower them in the second part of the year due to falling demand. However, prices did remain stable and there were no further reductions in November and December. “We see the signs of market recovery,” said an ALROSA representative. “In December, for the first time in three years, buyers faced shortages in some categories of diamonds when we couldn’t supply extra volumes of diamonds due to high demand.” Sightholders Still Refusing Goods ALROSA said demand is good along the full assortment of stones. Market participants say the rough in greatest demand is small stones of medium characteristics. The volume of stones rejected by sightholders remains within contract limits. The miner’s clients are allowed to refuse a certain percentage of the purchase volume specified in their contracts and the company let its buyers refuse more than the contracted allowance in August and September due to the stagnation at the market. Even so, most market participants say that the prices for ALROSA’s rough are still too high for the current polished prices. Even though sales were tough throughout 2013, ALROSA said it expects to meet its revenue targets. It also expects that rough prices will go up around 2 percent to 3 percent in 2014 and that demand will be stable though the year. It also expects its mining volumes to remain at 36 million carats in 2014. The company is planning to reduce its inventory by 1.2 million to 2 million carats, with most of this reduction taking place over 2014. Kristall Forecast Nikolay Afanasiev, the head of sales at Kristall Smolensk, Russia’s largest manufacturer, said he expected the situation at the retail market to remain flat in 2014, with a slight downward movement. “The decline in prices is not yet over and polished prices will continue to experience pressure from rough prices,” he said, adding that rough prices are still around 5 percent too high. Yet an even larger problem for the industry is the shortage of financing. “As demand for polished is going down, banks’ trust in the industry is also falling,” Afanasiev said. At the moment, he explained, companies and dealers have very little stock, but they are carrying too much debt to the banks and too many receivables from companies and paying them off may become a problem. Kristall, which sells most of its production outside Russia, expected to close 2013 with approximately the same sales as it had in 2012, but Afanasiev said those numbers were not a surprise because the year was very difficult. He said that one way to fight the stagnation in sales is to offer more services to clients. Kristall Smolensk is working on an internet system that will allow dealers, jewelry companies and private buyers all around the world to order stones online. Already, the company is selling a small volume of stones online in Russia. “Most of the sales are based on specific orders from jewelry companies, even dealers are working based on the orders they have, rather than what they have in stock,” said Afanasiev. He also noted that customers increasingly want to know the manufacturer of the diamonds because they are afraid of synthetics. Jewelry Sales Russian jewelers say 2013 was a tough year, with most companies reporting either a slight or no growth in sales compared to 2012. Most diamond jewelry is with stones of less than .30 carats. Nikita Nikolaev, commerce director of Yakutia-based Sakhayuvelir, said that people are also buying predominantly smaller certified diamonds. In 2012, companies said that people were looking for certified diamonds larger than .30 carats. Anatoly Korolev, director of Valery Gold, based in the south of Russia, said many customers still don’t understand the characteristics of diamonds, and are scared by the high price of stones with high characteristics. Many jewelers said that buyers are spending less on holiday presents. At the New Russian Style show held in Moscow in mid-December, most customers were looking for silver items or jewelry with small diamonds. Eugeniy Kustov, director of the Kostroma-based Kustov jewelry company, said that items with emeralds are very popular. He also noted that while Moscow prefers white and yellow gold, some regions still favor rose gold. At New Russian Style, many companies displayed items with emeralds, noting that these stones are more popular than the sapphires that were selling best in 2012. Larisa Ionkina from jewelry company Almaz explained that while sapphires were in fashion partially due to Kate Middleton’s engagement ring, emeralds and drop earrings were popular in 2013 because of a televised Russian soap opera, “The Magnificent Century,” which focuses on the life of a nineteenth-century Turkish harem.
GJEPC Launches Probe of Surat Synthetic Diamond Production
12.31.2013 - idex
The Gems and Jewellery Export Promotion Council (GJEPC) has launched an operation to discover which diamond factories in Surat are manufacturing synthetic stones. The move follows the alarm expressed in the global diamond industry in recent months over undisclosed lab-created diamonds being sold with natural melee stones, including in India. The GJEPC has appointed global management consulting firm A T Kearney and De Beers brokers Bonas & Co. to assist in the project of “establishing the current status, and to prepare a framework/guideline for the industry members to trade in natural and synthetic diamonds,” according to The Times of India. A Natural Diamond Monitoring Committee (NDMC) has also been created, including bodies such as the Bharat Diamond Bourse (BDB), the All India Gems and Jewellery Trade Federation (GJF) and the Mumbai Diamond Merchants' Association (MDMA), to take vital decisions pertaining to synthetic diamonds. Industry sources said experts from Mumbai have been in Surat in recent days with the aim of uncovering the scale of synthetic diamond production and how they are mixed with natural diamond parcels. A senior GJEPC official said, "We have sent a team of experts to Surat to find out units manufacturing synthetic diamonds. The manufacturers would be quizzed on various points. A detailed report will be submitted to the Natural Diamond Monitoring Committee (NDMC)."
