Gemstone Testers
Gemstone testers are essential tools used to evaluate the identity, authenticity, and properties of gemstones through various optical and physical testing methods. Different types of testers serve specific purposes—such as measuring refractive index, analyzing optical behavior, or examining internal features under magnification. These instruments enable professionals to distinguish between natural, synthetic, and treated gemstones, supporting accurate appraisal, quality control, education, and fraud prevention in the gem and jewelry industry.
Our Gemstone Testing Instruments
We offer a complete range of gemstone testers designed for appraisers, gemologists, traders, and laboratories. Each model is built for accurate, efficient, and field-ready use, supporting both professional and educational environments.
- Gem Refractometers
Measure refractive index (e.g., 1.30–1.81) to identify gem types and detect treatments or imitations. Ideal for verifying authenticity in daily appraisal work.
- Gem Polariscopes
Distinguish between isotropic and anisotropic stones, detect optical character and axiality—essential for identifying natural vs. synthetic gems.
- Gem Microscopes
Magnify surface and internal features to observe inclusions, treatments, or synthetic growth patterns with 10X–80X magnification and darkfield illumination.
- Additional Accessories
We also offer stone holders, filters, and illumination tools to enhance testing accuracy and workflow efficiency.
