Types of De Beers Diamond Testing Machines

De Beers offers a variety of machines, each designed for specific applications. The differences lie primarily in their automation level, size range of diamonds they can handle, and whether they are designed for loose diamonds or those mounted in jewelry. The choice depends on the specific needs of the user.

Machine Type	Description	Strengths	Weaknesses
DiamondProof	A handheld device for verifying natural diamonds in retail settings.	Portable, 100% accuracy for natural diamonds.	Cannot detect synthetics or simulants.
SynthDetect	Screens synthetic diamonds in both loose and mounted diamonds.	User-friendly, low referral rate for natural diamonds.	Requires user interpretation, some natural diamonds may be referred.
SynthDetect XL	A larger, more efficient version of SynthDetect, capable of testing larger jewelry pieces and loose diamonds.	High throughput, suitable for high-volume testing.	Requires continuous calibration, user interpretation is still needed.
AMS2	Fully automated machine for screening small, polished diamonds.	High speed, unattended operation.	Cannot screen treated diamonds, lower feed rates under certain conditions.
AMSMicro	Automated screening for melee diamonds (smaller than 0.003 ct).	High-speed screening for small diamonds.	Requires regular calibration, diamonds must be clean.
DiamondSure	Differentiates natural diamonds from synthetic diamonds and simulants.	Versatile, tests a range of diamond types.	Speed may be lower compared to automated machines.
DiamondView Zoom	Differentiates lab-grown diamonds from natural, and CVD from HPHT diamonds.	Detailed analysis, distinguishes between different types of lab-grown diamonds.	Lower throughput compared to fully automated machines.
DiamondPlus	Designed to screen for Type II HPHT treated natural diamonds.	Specific detection for treated diamonds.	Limited to specific diamond types and treatments.

Conclusion

De Beers offers a comprehensive suite of diamond verification instruments. Each machine provides a unique balance of speed, accuracy, and automation. The choice depends on factors like budget, volume of diamonds tested, and the need for automated operation.

FAQs

1. What is the principle behind De Beers’ diamond testing machines?

The primary principle is time-resolved photoluminescence. This technique involves exciting the diamond with a light source and then analyzing the light it emits. The specific characteristics of this emitted light reveal whether the diamond is natural or synthetic.

2. How accurate are De Beers’ diamond testing machines?

Accuracy varies by machine and diamond type. Some models, like DiamondProof, boast 100% accuracy for natural diamonds. Others, like SynthDetect, have a very low referral rate, meaning few natural diamonds are incorrectly flagged as suspicious.

3. What is the difference between SynthDetect and SynthDetect XL?

SynthDetect XL is a larger, more efficient version. It can handle larger jewelry pieces and has a higher throughput than the standard SynthDetect. However, both require user interpretation of results and continuous calibration.

4. Can De Beers’ machines detect all types of treated diamonds?

No, not all treated diamonds are detectable by all machines. Some machines, like AMS2, do not detect treated diamonds. DiamondPlus is specifically designed to detect Type II HPHT treated natural diamonds. Others might have limitations depending on the treatment type.

5. Are De Beers’ machines only used for gem-quality diamonds?

While they are widely used for gem-quality diamonds, some De Beers machines can also be used to test industrial-grade diamonds. The suitability depends on the specific size and application of the diamond.
