We expose the honesty gaps in the diamond And jewelry industry
What is a rose cut diamond you ask? It is a vintage cut diamond first produced about 500 years ago. It has 3 to 24 facets, has a flat bottom and a domed top with triangular facets that makes it resemble petals in a rose. Essentially it looks like only the top half of a diamond.
The rose cut diamond will appear physically larger than a full cut diamond because there is no bottom to the diamond. It is estimated that only 0.1% of all diamonds currently is a rose cut diamond.
The origins of a rose cut started in the 1500’s when diamond cutting techniques and knowledge was basic and the style reflects that simplicity. They were cut by hand and meant to sparkle under candlelight. The large facets performed nicely under low light conditions.
In the last 4 to 5 years it has gained in popularity partly due to celebrity endorsement. Jennifer Aniston received an 8 ct. antique rose cut engagement ring in 2012 from Justin Theroux. Recent history has seen a rise in vintage styled rings and the rose cut follows in this tradition.
We have been seeing more and more jewelry pieces featuring Black Diamonds. Black Diamonds are unusual, striking and fascinating to many consumers. And while most sellers of black diamond jewelry are ethical there are two huge issue that should be considered before purchasing a piece - IS IT REALLY A DIAMOND? IS IT A NATURAL EARTH GROWN BLACK DIAMOND?
Several years ago black diamonds hit the market and it was first used mostly as a fashion statement, usually smaller diamonds that are pave set along with white diamonds as a black and white theme. You can now find these black diamond jewelry in most of the major retail and online stores. It has increased in popularity and with it evolved to include larger engagement size black diamonds. With this increased popularity there have also been instances where consumers ended up owning black moissanite, or black lab grown diamonds instead of a genuine earth grown natural black diamond.
For consumers detecting the difference is next to impossible without special equipment. More so because moissanites are synthetic material that is carbon based and will fool most standard diamond testers. It takes a special tester that can detect moissanite from a diamond. To detect a lab grown diamond you will need a very expensive specialized piece of equipment that most jewelers do not have access to.
To BE SURE that the diamond is a genuine earth grown black diamond you should ask for a GIA document, a Colored Diamond Identification and Origin Report, that will identify the diamond as a genuine or treated fancy black diamond.
Do not get ripped off! Take time to get the proper documentation for confirmation and not have to worry a bit about your purchase.
GIA Discloses Companies Banned in Hacking Investigation
Rob Bates | October 27, 2015 JCK
The Gemological Institute of America is publicly disclosing the names of the 19 companies it says submitted diamonds that received altered grading reports due to unauthorized remote access of its computer system.
The companies can no longer submit stones to the lab, pending further investigation by Indian police.
A statement says that Indian authorities have also arrested two former employees of Tata Consultancy Services, the GIA’s systems provider, in the investigation. GIA said it did not know what they are charged with. Tata did not respond to a request for comment.
The discovery of the unauthorized access has led GIA to invalidate 1,042 grading reports. Their report numbers, along with the submitting companies, can be seen here.
GIA decided to release the names after “police informed GIA that the investigation has reached a point where we may now publish the client accounts that submitted the diamonds in question,” according to a statement.
GIA’s spreadsheet lists 19 submitting companies, mostly based in India, though at least one looks to be based in Hong Kong. Most of the clients submitted dozens of diamonds; three listed names submitted only one. At least two seem to share common ownership.
The spreadsheet lists the stones’ report numbers, carat weights, and shapes. It does not list their color and clarity, as they have may have been altered.
Several of the diamonds can be found online. For instance, Googling GIA report 1208363128—a 1.43 ct. round brilliant—leads to several online diamond listings, most of which have been removed.
Here is an online scan of one invalidated report (5203571257), which says the accompanying a 1.06 ct. stone has been graded D internally flawless.
GIA “strongly request[s]” that anyone in possession of any of these diamonds and grading reports return them immediately to GIA for examination at no charge.
Entering the affected report numbers into its online Report Check returns the message: “The report you requested has been invalidated; the report and the diamond must be returned to GIA for further review. The report will not be available in Report Check until the diamond is re-examined.”
At press time, it could not say how many of the 1,042 affected reports or diamonds have been returned.
There are many diamond and jewelry companies that are willing to make easier sales and extra profits by cheating. Both the consumer and the ethical companies in these industries must contend with all sorts of attempts to deceive or cheat. Now we have to deal with computer hacking on top of overgraded certificates, the application of substances that temporarily improve color, synthetic diamonds and so on.
On October 23, 2015 the Jewelers Circular Keystone reported by its online service that the GIA reported that their diamond grading report database was hacked. GIA has invalidated 1,042 diamond reports as the grades on those reports were changed through computer hacking.
Here is the article. Included is a link to a list of the affected reports. If any consumer finds their diamond included in this list then GIA requests that the diamond and grading report be sent to GIA. Anyone in this situation may contact us for assistance in doing this.

GIA INVALIDATES MORE THAN 1,000 REPORTS BECAUSE OF HACKING
Rob Bates | October 23, 2015 |
The Gemological Institute of America has invalidated 1,042 grading reports issued by its grading lab, as they bear grades that were altered after its system was accessed without authorization by former employees of its database support contractor, Tata Consultancy Services (TCS).
The list of affected reports can be seen here. GIA requests that anyone with these reports or their accompanying diamonds return them to its lab for inspection. Entering their numbers into Report Check will show that the reports have been invalidated.
The affected diamonds were mostly submitted in India, though some also came into GIA’s Carlsbad, Calif., headquarters. The stones were graded in whole or in part at various GIA locations, including its U.S. and India labs. The diamonds were submitted between November 2014 and September 2015; approximately 900 were submitted in July and August.
The issue was caught when the lab flagged certain grading discrepancies through its internal controls. It subsequently launched an investigation in conjunction with TCS.
The investigation revealed that one or more former TCS employees gained remote access to the system and made unauthorized changes to specific grades on behalf of certain parties. The clients who submitted the diamonds in question have been contacted and suspended from subsequent submissions to GIA pending further investigation.
The unauthorized changes involved both color and clarity grades, says spokesperson Stephen Morisseau.
GIA and TCS have made the results of their investigation known to law enforcement agencies in India, and they are actively investigating the matter, a statement said, adding that the incident has led GIA to strengthen its controls.
The Diamond Loupe
June 16, 2015
In his latest Diamond Intelligence Briefings, Chaim Even-Zohar recounts the discovery and the documented reversal of a treated diamond, upgrading the stone temporarily by several grades, discovered at the Antwerp IGI lab in November last year. According to the IGI lab, the reversal process - through acid boiling -, which was witnessed and documented in an affidavit, revealed the diamonds were treated with a coating, temporarily upgrading the color grade of a 3.03ct diamond four grades, from J to G+ color. The precise nature of the coating, which may involve an very thin film visible only at 500 times magnification, is unknown. The article adds that the treated diamonds IGI discovered do not come from the same source(s) as the treated diamonds that were discovered by the GIA recently. IGI reportedly informed relevant trade bodies after the discovery to let them decide on taking disciplinary actions, but according to Even-Zohar, they kept silent.

Carlsbad, Calif.--The Gemological Institute of America has cut off four clients traced to hundreds of diamonds submitted with an undisclosed treatment that improves their color by as much as three grades but fades over time.
The approximately 500 diamonds passed through the GIA’s laboratory in Ramat Gan, Israel in the past several months and now are circulating in the trade. The GIA sent out notifications about the still-unidentified temporary treatment Tuesday and is asking anyone in the trade with these 424 potentially treated stones to turn them back into the GIA for reexamination. (Approximately 76 of the 500 already have been reexamined by the GIA.)
The vast majority of the stones are 1 carat or larger, with a number of 3-, 4- and even 5-carat stones in the mix. A three color-grade jump for stones of this size would amount to a big difference in price or, as one industry player observed, “big bucks” for the sellers.
Meanwhile, the GIA has terminated the client agreements of the companies linked to the stones, as the lab “reasonably suspects” that the companies knew the diamonds were treated and did not disclose it, GIA spokesman Stephen Morisseau said.
The companies are listed online as: E.G.S.D Diamonds Ltd., L.Y.E Diamonds Ltd., Abramov Romok and Yair Matatov.
None of the four companies could be reached at the phone numbers listed online for them, all 972-54-397 numbers, mobile phones on the Israel Diamond Exchange’s cell phone system.
Only one of the four, Romok Abramov, replied to request for comment on the case via email.
In his email, he claims that “the amount of stones (that) can be submitted to GIA by one account is limited,” and so “Gabi” at E.G.S.D Diamonds, who presumably had hit his limit, asked him to submit stones on his behalf. “(I) never saw any of those stones and don’t have any idea if they were treated,” Abramov stated.
The GIA confirmed that there are indeed stone submission limits at its lab in Ramat Gan. And Morisseau said the lab does have a procedure whereby clients can ask for another client to submit stones on their behalf, but he doesn’t know if that procedure was followed in this case.
The GIA said it has notified the diamond bourses about what happened. In a statement issued Wednesday, the Israel Diamond Exchange said it called an emergency meeting of its board of directors upon hearing the news and has “resolved to identify the suspects” and act immediately to “take the needed measures.”
Morisseau said the GIA has not yet identified the treatment but are “actively researching it.”
The lab became aware of this potentially new color treatment when a client (not one of the four listed above) purchased one of these diamonds and the treatment began to wear off, leaving him with a diamond that had a much lower color grade than what he had paid for.
He returned the stone to GIA for reexamination. It was then that the GIA discovered the treatment and connected this stone with hundreds of others that had been submitted by the four companies.
While the GIA hasn’t drawn any solid conclusions yet, Morisseau said they “reasonably believe” that all of the approximately 500 stones have been treated but won’t be able to say definitively until the lab reexamines them.
He added that they are monitoring other GIA labs worldwide for similar submissions.
The report numbers of the potentially treated stones are posted on GIA.edu. Anyone who has purchased or has access to any of these diamond is asked to submit them to any GIA lab for free, expedited review.
“Visions of Beauty” is a video blog featuring customer directed custom designs ranging from the sublime to definitely ornate. It could be modern, vintage, classical, free form or anything else one desires. Customers bring to the table, pictures, sketches or ideas of what they want. With a good understanding of what they desire computer renderings are done for them to see if we understand their wishes. If the renderings are not right in their perceptions adjustments are made until they are satisfied. A wax model is then produced from the renderings which then show the exact size, height and width the ring will end up to be. If the wax is accepted then it is used to make the casting from which it is then finished and the diamonds are set. These are videos of the finished product. Each ring is exquisitely crafted to express the personality of the owner in creating their dream ring. Consider making yours today!
