Sample Price: $5,400
Benchtop Models: Prices typically range from ~$4,800 (VR-N3) to ~$198,000+ (for high-end models like VR-T7 for micro-area measurement or VR-T9 with multi-collimator).
Handheld Models: Prices generally range from ~$15,000 to ~$35,000+.
Factors Influencing Cost: The price varies based on the instrument type (benchtop vs. handheld), the level of analytical precision, detector technology (e.g., SDD detectors for higher performance), X-ray tube power, integrated software features, and any custom configurations.

VRAY's Jewelry Testers, especially XRF models like the VR-N3, are designed for straightforward operation:
Power On: Plug in the unit and press the power button. Allow it to complete its system initialization.
Place Sample: Open the sample chamber (for benchtop models like VR-N3) and place the jewelry item flat on the testing stage. For handheld units, position the measurement window directly on the sample.
Close Safety Door: Close the sample chamber lid firmly. The instrument will automatically confirm the safety interlock.
Select Test Mode: Using the intuitive touchscreen interface, select the appropriate test mode (e.g., "Gold Assay," "Precious Metals Analysis"). VRAY's one-click intelligent operation often simplifies this choice.
Initiate Analysis: Press the "Start Test" or "Analyze" button. The XRF process will begin, emitting X-rays and collecting fluorescent signals. Analysis typically completes in seconds.
View Results: The screen will instantly display the elemental composition (e.g., percentage of Gold, Silver, Copper) and the corresponding karatage.
Save & Report: Save the analysis data to the instrument's memory. You can then generate detailed reports (in PDF or Excel format) and even customize them with your company's branding.
Remove Sample: Once the analysis is complete and results are recorded, open the sample chamber (or lift the handheld unit) and remove the jewelry item. The unit is ready for the next test.

Begin by comparing competitors thoroughly. Crucially, vet manufacturer credentials: investigate their experience (VRAY boasts 17 years as a direct manufacturer), inspect their factory setup, and check customer reviews. Demand on-site product testing with your own samples. Conduct multiple test analyses to verify data consistency and reliability across different materials.

Choosing wisely ensures robust, accurate, and efficient operations for years. |
Yes, jewelry testers are effective, but their effectiveness depends on the specific tool and the material being tested. As you mentioned, standard diamond testers (usually based on thermal or electrical conductivity) are highly accurate at distinguishing diamonds from common simulants like Cubic Zirconia (CZ).
However, their limitations are significant:
Moissanite: Traditional diamond testers struggle with moissanite, as it shares similar thermal and some electrical conductivity properties with diamonds. While some "moissanite testers" incorporate additional conductivity tests, newer moissanite types can still bypass detection.
Lab-Grown Diamonds (LGDs): This is the biggest challenge. Because lab-grown diamonds have the identical chemical composition and physical properties as natural diamonds (including thermal and electrical conductivity), conventional diamond testers cannot distinguish between them.
Other Factors: Environmental temperature/humidity, surface dirt, and improper operation can affect results.
As a specialized manufacturer, VRAY primarily offers XRF (X-ray Fluorescence) Spectrometers, such as our VR-N3, VR-X5, VR-T series, and portable VR-H series. XRF technology is used for precise chemical composition and purity analysis of metals (like gold, silver, platinum, palladium), not for directly identifying diamonds themselves.
Metal Purity and Authenticity: VRAY's XRF analyzers achieve extremely high precision in metal detection; for instance, the VR-N3 can verify gold purity up to 99.99%. They quickly and non-destructively determine the content of various precious metals in jewelry, accurately differentiating plating, alloys, and pure metals. They can even identify undetectable adulterants like tungsten.
Indirect Diamond Authentication Support: While XRF doesn't directly test diamond authenticity, it analyzes the metal setting around or beneath the diamond, ensuring the authenticity and value of the mounting.
What did our happy clients say?
We just got the VR-N3 jewelry tester by VRAY, and it's fantastic for our high-volume jewelry shop. Its 99.99% gold purity analysis is incredibly precise, allowing us to quickly verify every piece. The compact 45KG (gross) benchtop design fits perfectly. It's truly streamlined our intake process. Highly recommend VRAY!
Our recent purchase of the VR-H5 Portable XRF Jewelry Tester was a game-changer for our mobile buying operations. Weighing just 1.6KG, its portability is unmatched, letting us accurately test gold and alloys on-site. The instant, precise readings are crucial for preventing fraud. VRAY delivers top-tier reliability for fieldwork!
The VR-X5 Jewelry X-Ray Machine we acquired recently has drastically improved our factory's quality control. Its high precision for precious metal analysis ensures all our products meet exact specifications before shipment. The non-destructive testing and speed are indispensable. For superior manufacturing standards, VRAY is simply the best!
Investing in VRAY's VR-T9 Benchtop jewelry tester was a strategic move for our refining lab. Its multi-collimator technology provides unparalleled accuracy for complex precious metal assays. The $38,000 price reflects its cutting-edge capabilities. Data is always spot-on, making our operations more efficient and trustworthy. VRAY comes highly recommended!
