A Detection Dictionary
Having the right testing equipment is as necessary as a scale for any diamond business today, but selecting the right machine isn’t easy.
![Devices that can detect or screen out lab-grown stones and simulants are as vital to diamond businesses today as a loupe or a scale, experts say. Pictured here is one such device, the DiamondSure from De Beers Group. 20211027_De Beers Ignite detection header.jpg](https://uploads.nationaljeweler.com/uploads/a57a9aedad9a132fe83a1b16552a98a4.jpg)
This past summer, diamond dealers, manufacturers, and designers were presented with a rare opportunity—to see and experiment with more than a dozen diamond testing instruments in one room.
Held at 580 5th Ave. in New York’s Diamond District, the Diamond Technology Showcase featured instruments from De Beers, Alrosa, the Gemological Institute of America and other manufacturers, pieces of equipment that are vital for any fine jewelry business today.
Lifelong diamantaire Matthew Schamroth, a vice president of the Diamond Manufacturers & Importers Association of America and head of the DMIA’s Diamond Integrity Committee, likens the necessity of these instruments to something as simple as a scale.
“You can’t open your doors without a diamond scale. You have to know the weight of what you’re sending to somebody.”
Dealers, wholesalers, designers, manufacturers, and retailers today also need to know: Exactly what do I have in front of me? Is it a natural diamond, a lab-grown diamond, or a diamond simulant?
They are straightforward questions but, unfortunately, there is no one machine that can provide all the answers.
When National Jeweler did a roundup of diamond testing devices in 2018, several of the experts interviewed noted there is no “magic bullet,” meaning one device that does everything and is relatively compact and affordable.
The same holds true today. Companies often use a combination of machines in concert and, in some cases, have to submit stones to a grading lab for final verification.
“What device you use depends on what your needs are,” Schamroth told National Jeweler when one of its editors visited the showcase in July.
Companies need to ask themselves: How do goods flow through the office? What technology, if any, is the company currently using to screen diamonds? And, if the company has multiple devices, is it incorporating all the technology that’s out there?
It’s also worth pointing out there are very few detection devices on the market today, meaning instruments that give the user a definitive result of a natural or lab-grown diamond.
Most instruments are screening devices, meaning they “screen out” potential lab-grown diamonds, diamond simulants, and/or treated material that require further testing.
Again, there are no easy answers.
What follows on these pages is a breakdown of the devices National Jeweler was introduced to at the Diamond Technology Showcase along with a summary of what each machines does, what type of company uses it, and its cost.
Also listed are three rates measured by the Assure Program, the Natural Diamond Council’s testing regimen for diamond verification instruments.
As defined by Assure, the false positive rate measures the ratio of lab-grown diamonds that are mistakenly identified as natural by each machine. A rate of 0% is most preferable; the higher the percentage, the higher the risk of passing a lab-grown diamond as a natural diamond or simulant.
The diamond accuracy rate refers to the ratio of natural diamonds correctly identified as natural. Overall, a higher rate is preferred, although it is worth noting that this rate does not factor in the false positive rate.
The majority of instruments listed also have a referral rate. The referral rate is the percentage of stones that cannot be positively identified as natural diamonds; the higher the percentage, the more stones that will require further testing.
Companies can use the “Assure tested” sticker on their devices for two years.
After that, manufacturers need to submit them for renewal of their certification in order to keep referring to the machine as Assure tested, NDC’s Head of External Affairs and Industry Relations Raluca Anghel explains.
She says some instruments were up for renewal earlier this year, but their manufacturers were granted an extension in order to allow the Assure Program time to open a second lab in Antwerp (testing will continue at the Underwriters Laboratories facility in Canton, Massachusetts), and to update its sample of testing stones to reflect the latest lab-grown diamond manufacturing technologies.
In addition, updated sample sets will be tested in triplicate for the first time, uncertainty ranges will be reported for all metrics, and Assure will introduce jewelry testing with a mounted stone sample set.
Some manufacturers confirmed to National Jeweler their plans for submitting, or resubmitting, their machines for Assure testing this fall; those are noted in the text.
Rates included in the description of each machine reflect the results of the original round of Assure testing, unless otherwise indicated.
Updated information on their performance will be available on the Assure website, as well as in the digital version of this story, when available.
