YEHUDA SHERLOCK HOLMES 4.0 detected 100% of lab-grown diamonds with the Assure 2.0 testing

The Yehuda Sherlock Holmes 4.0 technology was tested by the Natural Diamond Council’s ASSURE 2.0 Program, achieving a “Zero Diamond False Positive Rate.” This means that the Sherlock Holmes 4.0 successfully detected 100% of the lab- grown diamonds tested.

It identified all lab-grown diamonds across all four sample categories: “Primary Loose Sample,” “Smalls Loose Sample,” “Primary Mounted Sample,” and “Smalls Mounted Sample.”

According to the Natural Diamond Council’s ASSURE Program website:

“The ASSURE Program evaluates the performance of Diamond Verification Instruments through rigorous testing with highly challenging sample sets.”

“The ASSURE sample set is specifically designed to challenge the instruments and ensure that the test results are ‘future-proof.’ For instance, the sample includes synthetic diamonds that are not yet commercially available in the jewelry industry.”

Key highlights from the testing:

  • The Sherlock Holmes 4.0 was tested by a novice operator.
  • It achieved a Zero Diamond False Positive Rate, detecting 100% of the lab-grown diamonds.
  • It scored an average 97.5% Diamond Accuracy Rate (the ratio of diamonds correctly identified as diamonds to the total number of diamonds). The optimal Diamond Accuracy rate is 100%. This means that, on average, 2.5% of natural diamonds in the four sample categories were misclassified as lab-grown. No other device (Under $18,000) tested by ASSURE 2.0 outperformed the Sherlock Holmes in this category.
  • Dror Yehuda, president of Yehuda Diamond Company, shared, “I was very confident that our technology would detect 100% of the lab-grown diamonds.”

“My dad is smiling from Heaven, and I couldn’t be prouder,” he added. “Protecting the people in our industry is our goal. It’s incredibly gratifying to me and my family that we have reached a detection level that will save so many from making expensive mistakes and damaging their hard-earned reputations.”

A key difference between our three devices (Dr. Watson, Sherlock Holmes 4.0, and Big Sherlock) and other detectors is that our devices connect to the customer’s phone via an app. This feature allows us to continually update the Yehuda app with improvements.

A lab-grown diamond detector, like any digital hardware, is only as current as its software. The Yehuda team is constantly updating the software to ensure our customers are protected when new types of lab-grown diamonds enter the market.

The newer, more challenging CVD diamonds on the market may not be detected by other devices, including older Yehuda models that have not been updated with the latest software.

Mr. Yehuda concluded, “To protect the industry, we are offering a $2,000 trade-in allowance for any older detectors (including Yehuda devices and those from other brands) originally costing over $5,000 when purchasing a new Sherlock Holmes 4.0. We believe everyone should be protected, even if they own devices from other companies.”

ASSUREDLY
Sherlock Holmes!

The Best Synthetic Diamond Detector is ASSUREDLY Sherlock Holmes.

The ASSURE program is an initiative of the Diamond Producers Association (DPA).
The impartiality of the data was checked by UL Laboratories.

Did you know the ASSURE Program is ongoing? That’s how important it is to be able to detect synthetic diamonds.

If there is ever a better synthetic diamond detector than the Sherlock Holmes by Yehuda, the ASSURE Program will let you know.

The complete list of test results – in alphabetical order – can be found at the ASSURE directory: https://diamondproducers.com/assure/assure-directory/

31 detectors have been comprehensively tested by ASSURE.
ASSURE comprehensively analyzes all 3 types of synthetic diamond detectors.

Three Types of Synthetic Diamond Detectors:

TYPE ONE
Detectors that can check only one stone at a time (mounted or loose)

TYPE TWO
Detectors that sort small (under 0.20 ct.) round diamonds into 2 groups – natural and synthetic. (Primarily used by gem labs).

TYPE THREE
Detectors that can check single stones (mounted or loose) AND multiple loose stones AND multiple mounted jewelry.

You need type three, right?

  • The Sherlock Holmes by Yehuda is type three.
  • Sherlock can check single stones, loose or mounted.
  • Sherlock can check a parcel of stones.
  • Sherlock can check jewelry pieces that are mounted with numerous stones

Of the 31 detectors comprehensively tested by the ASSURE program, only 15 were type three. The ASSURE program checked 2 different groups of diamonds by size:

1. Small diamonds under 2mm diameter.
2. Any larger diamond.

SH 3.0 uses the same detection technology as the SH 2.0
