SSEF Light box

SSEF Light box (small and large version) is equipped with a specific light source allowing the user to easily switch between three different colour temperatures (6000K, 4500K, 3000K). The 6000K illumination is provided with a normalized light intensity of 2’200 lux at 20 cm from the source (following the ISO standard 24016 for diamond grading). The other colour temperatures are useful for gemmologists for coloured stone grading and seeking to evaluate colour shifts or colour change (e.g. alexandrite-effect) of a gemstone (as seen in the photo).

Standardized lighting ensures that the colour of a diamond or coloured gemstone can be viewed consistently across different environments and conditions. This consistency is essential for an accurate and reliable colour assessments. A standardized lightbox allows gemmologists (and traders) to compare gemstones against each other under identical lighting conditions.

This system is applicable to coloured gemstones, diamonds, and pearls.
