And Why Our Laboratory
is Different

We maintain one of the most advanced testing laboratories in the world for authenticating gold and diamonds. Our internal processes combine customized equipment, proprietary protocols, expert interpretation, and multi-stage verification to deliver results that eliminate uncertainty and provide absolute confidence. While the depth of our laboratory goes far beyond standalone machines, industry professionals often ask us which equipment we would recommend for their own independent use.

Below, we highlight two manufacturers whose products represent best-in-class performance within their categories: one is an X-ray fluorescence machine for testing precious metals, and the other is an ultraviolet fluorescence system for diamond verification. These machines offer excellent standalone capabilities for professionals building or enhancing their own testing programs, and they are backed by people we know and trust.

Gemoro XRF by SciAps

X-ray fluorescence (XRF) remains the standard for non-destructive analysis of precious metals, particularly for detecting counterfeit materials and determining alloy composition. Among the available options, we consider the Gemoro XRF by SciAps to be the best solution in its class. Its advanced silicon drift detector (SDD) delivers fast, high-resolution elemental analysis, supported by a modern software platform, USB-C interface, and responsive development that continually enhances detection capabilities, including improved plating identification.

We have been very impressed with the people behind the Gemoro XRF. Vance Kessler has made himself directly available whenever needed, ensuring clear communication and a smooth process in acquiring equipment. His depth of experience with both the technology and the broader precious metals industry has been evident in every conversation. Vance remains a reliable point of contact for us, always accessible and highly knowledgeable, with consistent support whenever we’ve needed assistance. We love working with him and strongly recommend both the equipment and his guidance.

DiaTrue by OGI Systems

Ultraviolet fluorescence plays a critical role in diamond verification, particularly when screening for lab-grown diamonds and simulants. Among the available options, we consider OGI’s DiaTrue series to be the most effective solution for detecting CVD and HPHT, as well as identifying cubic zirconia and moissanite. The system accommodates both loose stones and mounted jewelry, delivering fast and consistent results across various sizes, shapes, and settings. Its design allows professionals to perform reliable screening with minimal preparation, making it well suited for both ongoing commercial use and high-volume evaluation.

We have been consistently impressed by the people at OGI Systems. Dani Benzano has always been available to answer questions, accommodate specific needs, and ensure that we received exactly what was required for the operation. His willingness to be personally involved, even in small details, speaks to the company’s commitment to long-term professional relationships. In the U.S., Mitch Gilbert has provided excellent ongoing support with the same level of responsiveness and technical expertise. We’re pleased to work with them and to recommend OGI without hesitation.
