The Lucara Diamond Corporation has made most of the discoveries of very large rough diamonds in recent years at their Karowe mine in Africa. Now they have made their mark on the diamond industry in a new way with the introduction of their Clara Diamond Solutions System.

Since the founding of the modern diamond industry, the diamond mining companies have offered their product for sale to the diamond manufacturing sector in assortments or boxes. The manufacturers had to buy the entire box or not without being able to select from it just the stones that suited their manufacturing plans. It was an arrangement that suited the mining companies well but not the manufacturers and DeBeer’s had the market power to make it stick. This is what Lucara has changed.

With Lucara’s Clara Diamond Solutions System, the manufacturers buy only the rough diamonds that they need for the polished diamonds they intend to produce. In fact, they upload the exact specifications of the diamonds they want to produce and the Clara System matches the order with the appropriate rough. It even shows the buyer the best manufacturing plans by providing scans from Sarine Technologies’ Galaxy cut planning machines.

The Clara System was introduced last December and the rough diamonds sold achieved an 8% premium over what they would have earned in a regular tender. It is a win win since the manufacturing sector may be paying more for the diamonds they want, but they are avoiding the excessive inventory costs for the diamonds they don’t and the cost of reselling what they don’t want in the secondary market.

The Clara System works best for rough diamonds 1 to 8 carats which is the bread and butter of the diamond industry. These diamonds are not the mainstay of the Lucara Corporation which has made most of its money in the big diamonds it has discovered. But the selling or spreading of the system to the rest of the industry has great potential to improve the efficiency of the entire system and improve the pressure on the midstream.

For decades, Hollywood starlets have worn jewelry that they did not own to the Oscars and other high profile events. This jewelry is lent to them by famous jewelry artisans because what the starlets wear gets lots of coverage on TV and in magazines.

One of the newest and most interesting trends in the jewelry trade is something similar. It is the rental of fine jewelry to the general public for short periods of time. A handful of jewelry rental companies have come into being in the last decade or so that rent fine jewelry, usually for 5 day periods of time. There are also several retail jewelers that have opened rental departments within their stores.

These companies have discovered that there is a demand for rental created by the fact that it is prohibitively expensive for ordinary people to purchase jewelry for a specific event. If she is attending a wedding, charity event, holiday party, corporate event or any situation where she wants to impress and not be seen wearing the same, old jewelry, renting is far more affordable than buying. Many rental customers are women who deal with clients on a regular basis in sales, real estate, banking and wealth management.

Some rental companies (Flont, for example), charge membership fees ranging from $59 per month to $379 depending on the cost of the jewelry she wants to rent. Others, such as Adorn, do not assess membership fees and are single event rentals. These companies report that about 10% of their customers end up purchasing pieces.

There is concern and debate within the trade as to whether this trend is a threat or benefit to the high end retail jewelry trade. Flont’s founder and CEO believes they are creating future clients for the retail trade because renting the jewelry leads to enhanced appreciation of it. “You never rent the engagement ring,” she says. “And you can’t get away from the personal touch of buying an anniversary band.” She’s probably right about that.

Last summer the Federal Trade Commission (FTC) revised its guidelines regarding the marketing of diamonds in ways that were widely interpreted as a victory for the lab grown diamond industry. The previous guidelines had defined a diamond as a “natural” product. The new guides define a diamond simply as “a mineral consisting essentially of pure carbon in an isometric system.” This change was interpreted as putting the lab created product on an equal footing with the product mined in nature.

The FTC also dropped the word “synthetic” from its list of recommended descriptors of lab grown diamonds as confusing the public into thinking it was not a real diamond. It also allowed the use of the term “cultured” to describe lab grown diamonds but only if accompanied by other descriptors clearly indicating the product is lab grown. Even with these changes, the only product that can be described simply as “diamond” is one found in nature. All lab grown products must contain some qualifying descriptor indicating their origin.

So, does this mean, as the lab grown industry hopes, that the difference between the two products will dissolve and there will be just one market for diamonds whether lab grown or mined in nature? Probably not.

Remember, DeBeers announced last year that they will begin selling lab grown diamonds at $800 per carat with the express purpose of lowering the market price of lab grown diamonds to make them a separate product category and not a true substitute for the mined diamond.

A report by Baine & Company, reported in Rapaport Magazine, found that lab grown output is rising 15-20% per year and that prices of the polished grown product had declined significantly due mostly to declining production costs. That finding was confirmed by other analysts.

The lab growers dispute the impact of DeBeers entry into the lab grown market noting that most of DeBeer’s offering are small diamonds set in mountings which is unlikely to impact the sale of larger, loose lab grown diamonds. Nevertheless, the Baine report says the price of large, loose stones had declined significantly.

Another analyst cited in the Rapaport article, says there is significant consumer demand for a one carat lab grown diamond under $1000 but not for those costing $4000 or $5000. If he is right, and the trends noted in the Baine report continue, the markets will separate themselves and lab grown diamonds will settle at the high end of the fashion jewelry niche.

Debeers To Sell Synthetic Diamonds

Posted by & filed under Blog.

As any follower of this blog or the Hull Loan System facebook page knows, diamonds gown in a laboratory have improved in size and quality enough to be used in jewelry and are making inroads into the retail jewelry sector.  Some retailers, such as Wedding Day, have started stocking and selling lab grown diamonds almost exclusively marketing them as eco-friendly.  They are also cheaper than diamonds mined in nature and could potentially become much cheaper as mass production techniques improve.  Currently, lab grown (aka Synthetic) diamonds sell for about 50% of the price of a diamond mined in nature.  A one carat round synthetic diamond sells for about $4000 compared to $8000 for a comparable, naturally mined diamond.


Global mined diamond production last year was about 142 million carats, compared to about 4.2 million carats of lab grown production.  That’s only 3% of the market but it is up from 1.5% just a few years ago.   Everybody in the trade is anxious about the effect that lab grown diamonds will have and the diamond mining companies are some of the most vocal critics and opponents of them.  Debeers chief executive, Bruce Cleaver, says that synthetic diamonds are “not special, they’re not real, they’re not unique.  You can make exactly the same one again and again.”


Debeers has always said that it would not sell synthetic diamonds, but get this: They are very good at making them.  Debeers has been growing diamonds in the lab for decades, both for industrial purposes and also for research purposes: to understand the differences between diamonds made in nature and those made in the lab so that they have the means to reassure customers they are buying the real thing.


On May 29th, Debeers reversed itself and announced that it will begin to sell synthetic diamonds produced in the company’s Element Six facility. This decision reflects how serious Debeers regards the threat of synthetic diamonds moving into the retail jewelry sector.  Debeers announced they will sell their one carat round synthetic diamonds for $800, compared to the current market price of $4000 for synthetic and $8000 for naturally mined.  They also announced that their synthetic diamonds will not be graded since “they don’t deserve to be graded”.  Clearly, Debeers strategy is to disparage the product and undercut it’s value so much as to make it not a substitute for a naturally mined diamond.  At the same time, they intend to create a small profitable business in it own right trying to transform the market for synthetic diamonds into a small, niche, better than costume jewelry but not directly competing with naturally mined diamonds.

Squeeze on the Midstream

Posted by & filed under Blog.

A new research paper by the Rapaport Group provides a good overview of the current state of the diamond market. As late as the early 1990s, the Debeers Company controlled about 80% of the rough diamonds coming into the diamond pipeline. They used that control of diamond supply to maintain stable and modestly increasing diamond prices. Today, the 3 largest diamond mining companies, Debeers, Alrosa and Rio Tinto combined control less than 60%. There are new players in the market, more competition and more price volatility.

Diamond mining companies sell their rough diamonds to manufacturers who cut (polish) rough diamonds into the finished product that is sold to retailers (or wholesalers). The mining companies insist on getting paid in cash in order to fund continuing investment in their operations. Manufacturers have a hard time selling their finished product for cash to retailers and often lend them diamonds “on Memo” for them to sell, waiting to get paid until the inventory sells. A wait of six to nine months after their initial outlay for rough is not unusual. The manufacturers need financing to fund the purchase and stockpiling and that has historically been provided by European, Israeli and Indian Banks.

But the banks have become skittish about the midstream and are pulling back the amount of credit they are willing to extend. They believe “the midstream is congested with too many players and too many stones…the diamond sector is still operating in an oversupply environment with inventory largely stuck in the midstream…That is part of a long term correction the polished diamond market is undergoing, resulting in a prolonged decline in polished prices…The RapNet Diamond Index (RAPI) fell for the sixth straight year in 2017.”

The accompanying chart shows the decline in prices, the predictable result of oversupply. Consequently, three major banks have closed their diamond lending departments, resulting in $2 billion of credit either shifting to other banks or being lost to the trade. The remaining banks will surely cherry pick the dislocated manufacturers on the basis of their credit worthiness with the rest resorting to alternative financing, self financing or leaving the trade.Diamond Price Chart

Since the advent of modern diamond grading about 80 years ago, gemological laboratories have graded diamonds for carat weight, cut, color and clarity using some tools but applying human judgments. Scales, of course, were used to determine carat weight. But loupes, microscopes, millimeter gauges and master color grading diamonds were the tools used to apply standards to the diamond under observation so that a human could make judgments as to the color, clarity and cut grade to give the stone.

And that has led to controversy at times. Everyone in the trade has heard stories of the same diamond being sent to the same lab twice and getting a different grade the second time. And some labs have reputations for grading standards that are more lenient than others. Retailers know which lab to send a diamond to if they need a certain grade to justify their investment in the stone.

Now comes Sarin Technologies to change all that. Sarin is an Israeli company that makes MRI like machines for the mapping of inclusions in rough diamonds and for planning the cutting of rough into finished stones. Now they have produced machines to automate the grading of diamonds. Sarin’s CEO, David Block, says they have tested their clarity grading machine on approximately 20,000 diamonds and their color grading machine on about 10,000. He tells Rapaport magazine that they have shown “greater accuracy and consistency than manual grading by gemologists.”

Sarin has partnered with certain retailers to use their machine graded diamonds as part of the retailer’s “branding” efforts. The Sarin lab reports will also include data on the diamonds’ light performance, a feature that originated with the Gemex reports but has not been embraced as much as I expected it to be.

The big question is whether this will be a competitive option to lab reports from the big gemological labs or will Sarin eventually sell the machines to the labs? Will the big gemological labs embrace them or find fault with them? As the creator of the diamond grading system, the response of the Gemological Institute of America (GIA), in particular, will be especially interesting to watch. Stay tuned

As The Times Change

Posted by & filed under Blog.

Among the most pressing challenges to the diamond industry is the need to lift consumer demand. Historically consumer demand has been principally related to marriage. Consequently, diamonds have been marketed as symbols of eternal love and commitment. But millennials commitment to marriage is less than previous generations. They are marrying later, less often and it is seen more as a choice than a necessity.

The Diamond Producers Association led the way in altering the industry’s marketing campaign with its Real is Rare commercials (see my post on that below). Now comes Forevermark with a new campaign to support what they see as an emerging trend in the diamond market, the self purchasing female.

Forevermark’s research shows a big increase in self purchasing of diamond jewelry by women to about one-third of total sales. They think that reflects the shifting role of women in society and the changing attitudes that account for it. Their research shows a new model of femininity emerging with 82% of women globally preferring to be considered strong rather than sweet; with women no longer defining themselves as much by their relationship status; and with relationships or marriage, if it is chosen, more about personal growth and united goals. Women have become the largest emerging market with a global income of $5 trillion.

To tap into this emerging trend and the shifting diamond market that it portends, Forevermark is launching a new ad campaign to support and promote this new growth segment of the market. Diamonds can be about love but they can also be about “celebration, growing up, achievement and success.” They can represent a woman’s “inner character and qualities…her individuality and personal development.” Modern milestones have shifted, says Charles Stanley of Forevermark. Diamond jewelry is now purchased to mark coming of age, job promotions, graduations and financial success. Forevermark’s campaign is intended to encourage this trend. The ads will run from October to Christmas. Look for them.

DeBeers’ Forevermark Unveils Black Label Collection

Posted by & filed under Blog.

442x480xforevermark_black_label_five_shapes_group_jpg,qitok=p0t6cyny_pagespeed_ic_rAQ34O-i_JA number of years ago, the DeBeers Corporation saw its influence over the supply of rough diamonds into the retail pipeline decrease as more players entered the field independent of their marketing network. They correctly saw this as a permanent change and responded by going downstream, opening their own retail outlets and “branding” their finished jewelry as Forevermark. This echoed their “Diamonds are Forever” advertising campaign of earlier decades.

Now, they have introduced a new Black Label Collection of diamonds that they say is the “best representation of the most beautiful of our diamonds. These diamonds, they say, are for light lovers only. Well, who isn’t a light lover when it comes to diamonds? That is what we find beautiful about diamonds, the optical effects: the brilliant return of light to the eye, the dancing of light that we call scintillation and the flashes of color that is caused by the separation of white light into the spectral colors.

The Black Label Collection, says DeBeers, does this to a degree not seen before, especially with fancy shaped diamonds. The Black label Collection, they say, are the world’s most beautiful and symmetrical diamonds. Great emphasis is put on the symmetry of the cut. In creating this collection, DeBeers along with HRA Group spent 10 years developing perfectly symmetrical fancy shaped diamonds. The perfect symmetry extends beyond the bellies and shoulders to the facets themselves and is said to account for the brighter, more sparking fancy shaped diamond that was their goal.

The Black Label Collection is intended to appeal to Millenials to give them something different. DeBeers named the arrow pattern seen under magnification in a perfectly symmetrical diamond the “Compass of Light” in an attempt to signify to Millennials that this is a diamond cut to a degree of perfection beyond ideal. The ideal cut is a range of parameters that makes for a beautiful stone, but the Black Label is an even narrower range of parameters. I would suggest that you should expect to pay more.

Christie’s Celebrates 250 Years in Business

Posted by & filed under Blog.

The English auction house, Christie’s, is celebrating its 250th year in business. As the interesting article in Rapaport’s December issue reports, the auction house was started by a Scot, James Christie, born in Perth, Scotland in 1730. Christie went to London in 1750 and found work with a Covent Garden auctioneer, from whom he learned the trade. He held his first auction under the name of Christie’s on December 7, 1766, and included among the lots sold was a ruby and diamond buckle. So jewelry has been among the prominent items sold at Christie’s since the very beginning. Christie’s first ever all jewelry auction was held February 18, 1772.

James Christie died in 1803 and the firm was taken over by his son, also James, who was in turn succeeded by his son George Henry Christie in 1831. In 1889, the great grandson of the founder retired as the last member of the family to work at the auction house, although the name remains to this day.

Over the years, Christie’s has auctioned some of the world’s largest and most famous diamonds (and other gems as well); the jewelry collections of royalty, the famous and wealthy, and the world’s most famous designers. Among the famous diamonds sold at Christie’s auctions are the Wittlesbach, the Archduke Joseph, the Emporer Maximilan, the Oppenheimer Blue, the original diamond ring of Mary, Queen of Scots and the Elizabeth Taylor Diamond. Christie’s has sold the jewelry collections of Queen Charlotte, wife of King George III, Empress Eugenie, wife of Napolean III, the wives of Aga Khan, the Duchess of Windsor, Princess Margaret, Elizabeth Taylor as well as many wealthy socialites whose names are less familiar. They have sold the world’s most famous designers including Cartier, Van Cleef & Arpels, Tiffany, Schlumberger, Bulgari and more.

Christie’s first expanded overseas in 1958, opening an office in Rome. Today, they hold auctions in Geneva, Hong Kong, New York and Dubai as well as in London. Along with Sotheby’s, Christie’s is the preferred venue for the sale of great collections and estates as well as for the fabulous and colossal new diamonds just coming on the market. This is a great company with a long, rich tradition that is still going strong after 250 years and appears to have a great future ahead.

This post is abstracted from an article in Rapaport Magazine by Shaun Sim about technological advances in the diamond cutting industry. Historically, diamond cutters inspected stones for flaws with nothing more than a 10X loupe and their eyes. In the 1980s, computer applications began to aid them in locating flaws in a rough diamond but a window still had to be polished to reveal the interior of the stone.

In 2009, Sarin Technologies, based in Israel, introduced the first product in its line of machines that do inclusion mapping in rough diamonds. It was capable of scanning and mapping the inclusions in a rough diamond without needing to polish a window. Sarin’s machines now take a video of the exterior of the stone while using a scanner that maps the interior of it. It is similar to the magnetic resonance imaging used in hospitals and is a breakthrough in materials engineering.

The data from the video and scanned imaging is fed directly into another Sarin machine that is designed to facilitate the planning and cutting of the rough diamond. This machine offers options for visualizing the number of diamonds that can be cut from the rough stone and how the stone must be divided to optimize the number and size of the finished diamonds produced.
