• AGS Laboratories Will Resume Grading Laboratory-Grown Diamonds

    The nonprofit lab expands its mission of consumer protection to the laboratory-grown market AGS Laboratories is pleased to announce that they will resume grading laboratory-grown diamonds, a service they previously offered until 2012. The enhanced report is the result of over a year of research and development to create a product that helps jewelry buyers better understand the qualities of their laboratory-grown diamonds. The Laboratory-Grown Diamond Grading Report will be in a digital format and is a component of Only My Diamond® (OMD) for Laboratory-Grown Diamonds, which will contain additional educational information, including a special section on the 4Cs of laboratory-grown diamonds. Other noteworthy features of the report include: Unique color and clarity grading nomenclature, enhanced educational information, and a focus on precision cutting.

  • The Golan Q1 2020 Diamond Market Report–LGD

    Healthy lab-grown sales were reported in January and deep into February. Rough LGD supply from China was halted due to theChinese New Year vacations that started in mid-January. Factories were due to open in February, however, production did not startuntil late in the month, and then only partially. The travel ban posed an obstacle to purchasing, with producers willing to ship only if buyers were willing to accept parcels withoutseeing them first. That kind of trust is limited. And by mid-March shortages in HPHT were reported.According to LGD manufacturers and wholesalers, sales of polished ended abruptly in early March and in early April was yet toresume.LGD prices kept steady in the first couple of months, while business continued. The exception was a price decline in thirds andquarters over a supply/demand imbalance. In addition to the pandemic induced impact, patent issues also impacted CVD activity, evident in February. As a result, HPHT was inbetter demand, leading to firm pricing.It is difficult to predict what will happen to LGD demand and prices once the COVID-19 storm passes and trade resumes. One LGDjewelry…

  • CDC announces the world’s largest untreated High-quality Created Diamond

    Recently, Created Diamonds Company(CDC) announced up-to-date the world’s largest high-quality created diamonds, which is supreme in both colour and clarity while without any post-growth treatments or enhancements. Shortly the stone caused much of a stir in the LGD industry. The diamond has been identified by the IGI (International Gemmological Institute) with relevant specifications showing below: Weight: 7.06 carats, Color: F, Clarity: VVS2, Cut: 3EX, Fluorescence: None Provided by Hangzhou ChaoRan Diamond Co., Ltd.(ChaoRan), this super diamond was created through CVD ( Chemical Vapor Deposition) method. According to ChaoRan staff, before being designed, cut and polished ,the rough stone weighed 28 carats. And the final come-out of the polished stone reached 7.06 carat. Which made it currently the world’s largest unheated high quality CVD round diamond. CVD (Chemical Vapor Deposition) is one of the 2 methods to create diamonds. HPHT (High Pressure High Temperature) represents the other. Speakingof the 2 technologies, HPHT was applied years earlier than its counterpart CVD tocreating gem-quality diamonds. HPHT diamonds has already emerged in the jewellerymarkets in 2010; while CVD diamonds started to show up from 2013 . In terms of grades, the colour of HPHT diamond usually can reachto D-F, but most of thestones’ clarity ranges around SI.While according to the industry, the CVD technology seems alwayslack of control in colour stability. A large proportion of CVD products need post-growth treatments or enhancements in orderto get better grading . Statistic shows that, a USA based…

  • Lightbox Jewelry Seizes the Lab-Grown Diamond Moment

    Below, Coe talks to JCK aboutthe status of Lightbox’s new factory near Portland, Ore.; what the brand haslearned about consumers’ take on colored diamonds; and why the company recentlyintroduced grading reports for its products. What are your biggest initiatives for 2020? The opening of the new manufacturing facility in Oregon. It’s already well advanced. The building is complete and services are complete. They are literally installing reactors as we speak. It will come online the second half of this year and will give us significantly more volume of product—something like 200,000 polished carats per year. That will enable us to get into much wider distribution than today. Today, our production is significantly lower because we’re doing it out of Element Six in the U.K. This factory is a game changer. It’s going to ramp up over a period of time; the idea is that by the end of the year, it will be fully running. How are sales? They’re going well. Very positive. We’re doing a trial with Reeds—we’re in 45 of their doors and in two doors with Bloomingdale’s. The trial runs through the end of…

  • GSI ANNOUNCES LAUNCH of LGX Complete™ GRADING REPORT

    The grading report will be themost comprehensive available on the market today for lab-grown diamonds Gemological Science International (GSI), one of the largestgemological organizations in the world, announced today that it will startoffering its new LGX Complete™ for lab-grown diamonds that do not have anypost-growth treatments or enhancements. The LGX Complete™ is the mostcomprehensive grading report available on the market today for lab-growndiamonds. The new GSI report will include if the lab-grown diamond wasproduced by HPHT (High-Pressure High Temperature) or CVD (Chemical VaporDeposition) process and if it’s “As Grown,” which is a commonly used term inthe industry for lab-grown diamonds that do not have any post-growth treatmentsor enhancements. GSI is the only major laboratory to issue grading reports forlab-grown diamonds with these disclosures. As lab-grown diamonds become moreaccepted by consumers it’s important that all relevant information is in placein order to maintain consumer confidence in our industry. “Consumer confidence is key and consumers want more informationand complete transparency about the natural and lab-grown diamonds they arebuying, “said Debbie Azar President and Co-Founder of GSI.

  • Retail Margins Could Be Boosting Man-made Diamond Sales

    While lower prices as well as marketed ethical and sustainable benefits relative to that of natural diamonds has been the prominent narrative around man-made diamonds, a seemingly less-obvious factor is also likely helping to drive the product: the profit margin they offer retailers.  When analysing the wholesale and retail prices of unbranded man-made and natural diamonds, it appears that the retail gross margin of man-made diamonds in popular carat-sizes is as much as 1.8-times that of natural diamonds (see below figures). To further quantify this, for example, in some cases aretailer would theoretically only have to sell $5,000 worth of man-madediamonds to generate the same gross profit as selling almost $10,000 worth ofequivalent natural diamonds. Here, “gross margin” is considered to be aretailer’s top-line profit when selling a diamond, i.e. the sales pricerelative to the wholesale cost of the diamond.  This is important metric for a retailer selling bothman-made and natural diamonds because the theoretical high gross profit marginof man-made diamonds serves as an implied incentivize to prioritize sellingman-made diamonds over natural –as long as the profit margin differentialremains in place. Further,…

  • Canada Trade Releases Created iamonds Guidelines

    TheCanadian Jewellers Association (CJA) has issued a guide to advertisinglab-grown diamonds in response to a rise in marketing of the product toconsumers in the country. The CJA based its rules on a number of Canadian legal sources, including the Competition Act and the Canadian Guidelines for Gemstones. It also takes into account the US Federal Trade Commission’s (FTC) Jewelry Guides, as well as other international rule books. “These guidelines are intended to assist industry trade members in presenting lab-grown diamonds in compliance with Canadian law, and avoid consumers being misled by unsubstantiated or false claims,” the CJA said last week. The rules state that when used alone, the word “diamond” can refer only to a mined diamond. Sellers must state that a lab-grown stone is either a “lab-grown,” “lab-created” or “synthetic” diamond, with the descriptive term immediately preceding the word “diamond.” “Neither word shall be given greater prominence or emphasis than the other, nor may they be separated,” CJA noted. The group also urged retailers to make sure any claims from a supplier or manufacturer are verified and not misleading…

  • WD Lab Grown Dismisses Case Against ALTR

    On Friday, Carnegie Institution of Washington and M7D—the legal name of WD Lab Grown Diamonds—dismissed their patent infringement suit against ALTR Created Diamonds and parent company R.A. Riam. The case, originally filed in January in New York federal court, was dismissed without prejudice, leaving open the possibility it could be refiled. ALTR declined comment. WD chief executive officer Sue Rechner tells JCK viaemail, “We can’t comment on ongoing legal matters. We will certainly reach outas soon as we are able to share any information on the situation.” The case was one of three suitsthat WD filed last month. At press time, Carnegie Institution and WD still hadcases pending against two other pairs of lab-grown diamond companies: PureGrown Diamonds and sister company IIa Technologies, based in Singapore; andFenix Diamonds and owner Mahendra Brothers, based in Mumbai, India. Like its now-dismissed caseagainst ALTR, the suits charge those companies with infringing on Carnegie’spatents for growing diamonds with the chemical vapor deposition (CVD) methodand treating the diamonds after they are grown. M7D has licensed growingand treating technology from the Carnegie Institution since 2011. At press time, the other cases have not…

  • GSI CAUTIONS OF “TREATMENT IMITATION” IN LAB GROWN DIAMONDS

    Recently, Gemological Science International’s (GSI) Mumbailaboratory identified HTHP lab-grown diamond with what appeared to be a laser-drilledchannel. GSI researchers and scientists observed and studied this diamond sinceit would be highly unusual to laser drill a lab-grown diamond. Upon closerexamination, the “laser drill channel” was found to be a typical HTHP inclusionthat was cut open from top and pavilion. After this, the content of theinclusion was acid bleached out, while some residue was still present. Theremnants of the inclusion have a strong resemblance to a laser drill treatment– this treatment is generally used to “clean out” black inclusions and enhancethe appearance of a diamond. It is a common misconception that a diamond can be identified asnatural or lab-grown based on inclusions as the claim was made recently on GoodMorning America Investigates. In this specific case, a hasty and inaccurateconclusion could have been made that the diamond is natural, with theappearance of what seems to be a laser drill channel since there are norecorded cases of lab-grown diamonds with this treatment, nor would it currentlymake sense to laser drill these diamonds. “Diamond growing…

  • De Beers CEO Bruce Cleaver Talks Lab Grown and Patent Suits.

    De Beers chief executive officer Bruce Cleaver (pictured) talked with JCK Thursday, following the release of his company’s preliminary financial results for 2019. The results were, to no one’s surprise, not very good, with total revenue falling 24% and rough diamond sales falling 26%. But Cleaver feels the market has begun to turn thecorner, and here he discusses his reaction to the ruling in his company’slab-grown and patent lawsuit. Lab-grown remains a hot topic. Where do you see it going over the next year? We still feel that it’s a perfectly legitimate category, butit’s not the same as the natural. There is no doubt that the lab-grown businesshad a good Christmas, but so did the natural. The key remains allowingconsumers to make the proper choice. I have no doubt the prices will continueto come down in the lab-grown space. That trend has already started in 2019. With Lightbox, until we get the facility in Oregon up and running, I have little stock to sell elsewhere. The website has done very well. What is your reaction to the court ruling from Singapore, regarding De Beers subsidiary Element Six’s ongoing patent…
