Description

The GHEXA-24.0901-B Gem Microscope is a professional-grade gemological stereo zoom microscope optimized for jewelry appraisal, diamond grading, and gem identification. It features a continuous 0.67×–4.5× zoom lens (1:6.7 ratio) delivering standard magnification of 6.7×–45× (extendable up to 2×–225× with optional eyepieces and auxiliary lenses), a Seidentopf binocular head with 45° inclination, super wide-field WF10×/22 mm eyepieces, and a specialized jewelry stand with rotating base and adjustable inclination for ergonomic viewing. Built-in bright field (BF) and dark field (DF) illumination is provided by upper 7W fluorescent (or 1W LED) reflected light and lower 6V/30W halogen transmitted light, both brightness adjustable. This model excels in revealing inclusions, color zoning, fluorescence, and surface features in diamonds, colored stones, and jewelry items with exceptional clarity and contrast.

Specifications

Key Applications & Uses

• Professional diamond grading and certification (GIA/IGI-style observation of inclusions, cut, clarity, color)
• Gemstone identification and authenticity testing (emeralds, rubies, sapphires, synthetic vs. natural)
• Jewelry appraisal and valuation in gemological labs, retail showrooms, and pawn shops
• Detection of treatments, enhancements, fracture filling, and laser drilling in colored stones
• Quality control and inspection of finished jewelry pieces, settings, and mountings
• Research and education in gemology institutes, universities, and training centers

Frequently Asked Questions (FAQs)

What makes this microscope ideal for gemology? The built-in bright field + dark field system, rotating/inclinable jewelry stand, and strong transmitted halogen light are specifically designed for diamond and gemstone grading, revealing inclusions, color, and transparency with professional accuracy.

What is the standard magnification range? 6.7×–45× with the 0.67×–4.5× zoom and included WF10×/22 mm eyepieces; optional eyepieces and auxiliary lenses extend it up to 2×–225×.

Does it include both reflected and transmitted illumination? Yes — upper reflected (7W fluorescent or 1W LED) and lower transmitted (6V/30W halogen) lights, both brightness adjustable, with dedicated dark field capability for gem observation.

Can the microscope be used for photography or documentation? Yes — add a trinocular head upgrade (if not already configured) and C-mount adapter for attaching microscopy cameras to capture high-quality gem images.

What is the advantage of the rotating and inclinable stand? It allows easy repositioning of the gem or jewelry piece and adjusts the viewing angle for comfort and optimal lighting, reducing neck strain during long grading sessions.

Is dark field illumination built-in? Yes — the stand features integrated dark field for transmitted light, essential for spotting inclusions, feathers, and other internal characteristics in diamonds and colored stones.

What warranty and support does G-Hexa provide? 1-year standard warranty on parts and labor, with extendable options, preventive maintenance, and priority technical support from our Nashik-based team.
