According to our (Global Info Research) latest study, the global Gem Tester market size was valued at US$ 116 million in 2025 and is forecast to a readjusted size of US$ 149 million by 2032 with a CAGR of 3.6% during review period.
A gem tester is a specialized instrument used for identifying and analyzing gemstones. It helps jewelers, collectors, and gemologists identify different types of gemstones, assess their quality, and determine whether they are natural or synthetic. Its working principles typically include techniques such as refractive index measurement, specific gravity measurement, spectral analysis, thermal conductivity testing, and fluorescence testing. Gem testers are widely used in the jewelry industry, gem identification, and educational research, providing crucial support for ensuring the authenticity and value of gemstones.
In 2025, global Gem Tester production reached 822,670 units, with an average price of approximately RMB 136 per unit. The industry's average gross profit margin was approximately 28%.
The gem tester industry chain mainly consists of the following upstream components: near-infrared/ultraviolet light sources (such as ams OSRAM and Luminus), photoelectric detection and sensors (such as Hamamatsu and Vishay), miniature spectrometers and OEM modules (such as Hamamatsu miniature spectrometers, Ocean Insight, and Wasatch Photonics), and filters and optical components (such as Semrock, Edmund Optics, and Thorlabs); midstream components include complete machine/module and solution manufacturers, focusing on in-store rapid testing and lab-grown diamond screening; and downstream components are mainly distributed through jewelry tool distributors and channel partners (such as Stuller, Gesswein, and local distribution networks in various countries) to reach jewelry retail stores, processing workshops, diamond trading and recycling institutions, etc., and are complemented by after-sales repair and calibration, software/database updates, and third-party verification services to form continuous revenue and customer loyalty.
The gem tester market has seen continuous growth in recent years, driven by the development of the global jewelry industry and increasing consumer demand for gemstone authentication. With technological advancements, modern gem testers have not only improved in accuracy and efficiency but also incorporated more advanced technologies, such as artificial intelligence and machine learning, to enhance the intelligence of the identification process. These instruments can quickly analyze the physical properties and spectral characteristics of gemstones, helping professionals better distinguish between natural and synthetic gemstones, thereby meeting the market's demand for high-quality jewelry.
Currently, various types of gem testers are available on the market, ranging from simple portable devices to complex laboratory analytical instruments, suitable for different user groups, including jewelers, gemologists, and educational institutions. Furthermore, the rise of e-commerce platforms has increased consumer interest in purchasing gemstones online, driving up demand for portable gemstone testers to facilitate simple gemstone identification for individual users.
The future development trend of gemstone testers will mainly focus on three aspects: First, intelligentization will be a major direction, with instruments integrating more intelligent algorithms and data analysis functions emerging, making gemstone identification more efficient and accurate. Second, portability and user-friendliness will be further enhanced, with more simple and easy-to-use devices entering the market, allowing non-professional users to easily conduct gemstone testing. Finally, with the popularization of sustainable development concepts, the market demand for environmentally friendly materials and low-energy-consumption equipment will increase, propelling gemstone testers towards sustainable development.
