De Beers taps into polished diamonds market with first-time auction

Anglo America - De Beers

Anglo American’s De Beers, the world’s largest rough diamond producer by value, has decided to begin selling its own polished diamonds in auctions for the first time in its history.

The pilot auction, scheduled for June, will include a wide range of polished stones manufactured directly from the company’s own rough diamonds.

"The pilot auction, scheduled for June 29, will include a wide range of polished stones manufactured directly from De Beer's own rough diamonds." All the polished rocks will carry grading reports from both the International Institute of Diamond Grading & Research (IIDGR) — De Beers’ in-house grading unit — and the Gemological Institute of America (GIA).

“We are interested in testing the level of demand from polished buyers for diamonds that have a clear and attractive source of origin, and that offer the assurance of product integrity that dual certification provides,” Neil Ventura, the miner’s executive vice president of auction sales, said in the statement.

If successful, the process would provide De Beers with more insight into the polished market, while also helping consumers fill gaps in supply or inventory if they were unable to find goods at the company’s rough auctions, he added.

All registered De Beers auction buyers will be eligible to bid in the first sale, which takes place on June 29.

US Wobble Takes Shine off Pandora Sales

Pandora jewellery

Pandora reported strong growth in the first quarter, but US store closures and sluggish mall traffic dented its performance stateside.

Global sales jumped 9% year on year to $756.9 million (DKK 5.16 billion), while net profit increased 4% to $199.7 million, the Denmark-based volume jeweler reported Tuesday.

The rise was mainly due to a 46% surge in revenue at Pandora-owned concept stores, which came to $270.4 million, driven by an increase in the number of stores. In the US, revenue fell 7%, or 10% in local currency.

While the company added a net 21 concept stores in the US in the past year, it closed about 600 other points of sale in the fourth quarter of 2016 and suffered from a decline in mall traffic, the retailer explained.

A one-off shipment to Signet Jewelers-owned brand Jared a year earlier also had an impact on the sales decline. “The retail climate in the US remains difficult, which was reflected in our performance in the US for the quarter,” said Pandora CEO Anders Colding Friis.

Important Advice on How to Sell Your Diamonds

How-To-Sell-My-Diamond HowTo Sell My Diamond

If you are you considering selling your diamond, but feel as though you have no idea how or where to begin with the process?

This article will give you a few tips to help you along the way.

TIP #1 Diamonds are usually given to display love, making the sentimental value higher to the seller than the actual value to a buyer. Should you be in the market to sell your diamond, make sure you are ready to part with the diamond before begining the process.

TIP #2 Be sure of the quality and authenticity of what you are trying to sell. Make sure of the quality and the grade of the stone. This is most important for the ultimate value of the diamond. There have been many instances where a seller is committed to selling their diamond only to find out the quality isn’t as described when originally purchased.

There are Jewellers or services available, who will give an unbiased assessment of your stone. But it is far more valuable in the long run to get a report from a recognised Laboratory.

It is also recommended to verify the report matches the Laser inscription before placing your diamond on the market, to assure your diamond is the same stone should it not sell.

TIP #3 Now that you have an accurate report of the quality, make sure you get a realistic selling value. Believing the diamond holds a higher value than it truly possesses will lead to a challenging, frustrating experience which can be dragged out.

An appraiser can assist you with determining a fair selling, price so you can avoid this pitfall. Diamonds are priced in US dollars, so your diamonds price will be affected when converted to your local currency.

A good way to see current retail values is to visit online stores like or

TIP #4 There are many ways to sell a preloved diamond or diamond jewellery. Research your selling options to make an educated decision that works best for you. Be it an online market or exploring options through a local jeweller or dealer, be sure you are using the best option for your needs.

Example, if time is not of the essence, an online market or an auction house could be the best way forward. If you want a quick sale, visiting your local dealer may be the best option.

Gem Diamonds recovers 80 carat rough diamond

80 carat rough diamond

Another D colour Type II diamond weighing 80 carats has been recovered.

Shares in Gem Diamonds spiked on Thursday after the miner announced it had recovered one of the highest quality stones to come out of its Letseng mine in Lesotho.

The discovery of this 80 carat diamond comes less than a month after the miner announced the recovery of a 114 carat rough diamond. And two years after Gem Diamonds found a 357 carat rough diamond, which sold for $19.3 million.

Gem Diamonds has recovered four of the 20 largest white gem quality diamonds ever recovered, which makes of the Lesotho mine the world’s highest dollar per carat kimberlite diamond operation.

This Blue Diamond Is Natural—and Also Synthetic

Blue Diamond

The good news is, from everything we know, all lab-grown diamonds are detectable, and the detection devices are getting better and (somewhat) cheaper.

The bad news is that unethical people are still apparently devising new and innovative ways to cheat. Take GIA’s first sighting of a natural/lab-grown composite diamond with a fancy colored grade, which was first announced at the U.S. Jewelry Council forum on undisclosed lab-grown diamonds last week.

According to a GIA Lab Note published on Monday, the 0.33 ct. diamond was first graded fancy blue at the GIA’s New York laboratory. But what caught scientists’ attention was it had both nitrogen and boron defects. It is rare to see boron defects in a natural diamond—and even rarer to find both types of defects in one stone.

Further examination showed something else quite unusual: The stone was both type Ia and IIb diamond, another rare combination. (In fact, GIA reports running across that combo only once before, in 2009.) Finally, the truth was discovered. This was a colorless natural diamond with a small CVD coating on top. That coating gave it a fancy blue color when viewed from the table.

While the GIA note mentions that composites have been produced before, this is apparently the first composite GIA has discovered submitted (undisclosed) to its lab. This raises the possibility of more in the wild. This obviously is a troubling discovery—though someone with knowledge of the issue said at last week’s forum that he believes that GIA’s devices would be able to spot it.

Another lab exec told me producing these composites is likely not easy, or cheap, to do. But this will clearly be something to watch (and watch out for) in the future.
