Gem Microscope (0-45° Inclined)
Gem microscopes enable detailed examination of inclusions, surface features, and treatments, making it easier to differentiate natural stones from synthetics and identify any enhancements. A magnified view helps professionals assess a gemstone’s quality and authenticity. The R5S/6S series inclined-arm microscopes are stereo zoom models with specialized optics and advanced lighting, delivering sharp, high-contrast imaging. The adjustable tilt design provides flexibility and comfort during extended use, making them a great choice for laboratories, gem trading, and jewelry workshops.

Gem microscopes help reveal key details about a gemstone’s structure, composition, and any treatments it may have undergone. Examining both surface and internal features provides valuable insights for identification and grading.
- Surface Features
Scratches, etching, fractures, junction lines, twinning patterns, triangular growth marks, and color zoning can indicate whether a gemstone is natural, treated, or synthetic.
- Internal Characteristics
The type, shape, and distribution of inclusions play a crucial role in gemstone identification. Observing growth structures, twinning planes, and internal color patterns can help determine origin and authenticity.
- Interference Patterns
Using crossed polarizing filters with a conoscopic lens enables interference pattern analysis, which helps assess optical properties.
- Pleochroism Analysis
Placing a polarizing filter below the stone and rotating it reveals pleochroic colors. A quick rotation enhances the contrast between different hues.
- Microphotography
A camera attached to the trinocular eyepiece captures high-resolution images of microscopic gem features, useful for research and documentation.
