Diamond Microscope
Diamond microscopes are specialized instruments designed for diamond grading and identification, offering a precise and detailed view of a diamond’s cut, clarity, and fluorescence. These microscopes utilize vacuum suction technology to securely hold diamonds in place, ensuring 360° unobstructed observation from any angle. Equipped with a diamond manipulation stage, users can rotate the stone freely in any direction for a comprehensive inspection. The dual top lighting system enhances clarity for evaluating color, inclusions, and shape while also enabling fluorescence examination under UV light. The FGM-DS-161 and FGM-DS-171 diamond microscopes share the same features, differing only in their lens, ensuring accuracy and reliability in diamond assessment.
- These diamond microscopes offer enhanced performance in evaluating a diamond's color, clarity, shape, inclusions, and UV fluorescence, providing better results than standard gem microscopes.
- They significantly improve the efficiency of diamond grading by offering clear, detailed magnification for precise analysis.
- In addition to diamond inspection, these microscopes can replace traditional gem microscopes for gemstone identification, offering all the necessary features for comprehensive gem analysis.

High quality microscope head provides upright, high-resolution images with true-to-life colors and a strong sense of depth. It produces clear, three-dimensional views ideal for precise gemstone analysis, ensuring accurate color grading and detailed inspection of inclusions.

Illumination system | Bottom lighting | Equipped with high-quality darkfield bottom lighting, brightness is adjustable for optimal illumination. |
Top lighting | Includes 6500K daylight illumination and 365nm UV light, ideal for observing a diamond's shape, color, inclusions, and fluorescence characteristics. | |
Optical system | Requires high precision, providing an ample depth of field to generate clear and accurate images. This ensures a detailed study of a diamond’s clarity and color, as well as the identification of inclusions. The eyepiece’s view of the diamond varies with the angle, but the brain naturally combines these two images, resulting in a seamless, instinctive perception. | |
Operating system | Equipped with a specialized diamond handling platform, allowing precise yet effortless control of the diamond. This platform connects to a vacuum system to securely hold the diamond, maximizing your viewing field to encompass the entire range of movement. Its intuitive design lets you freely and flexibly rotate the diamond, ensuring comprehensive inspection without compromising image clarity. | |
