- [Aurora - The SSEF LightBox for professional-grade gem colour assessments](https://www.ssef-instruments.ch/shop/aurora-the-ssef-lightbox-for-professional-grade-gem-colour-assessments/) - Aurora 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. The advantages include: New generation of high-quality LED (manufacturer life-time: 10’000hours) No flickering 3 colour temperatures (6000K, 4500K, 3000K) Electronic touch screen for the selection of the colour temperature Highly effective glass diffusor specifically designed for diamond and gemstone observations Colour Rendering Index (CRI) of 98.4% Even distribution of the light intensity Inner part of the cabinet in normalized neutral Munsel gray Inner dimensions (length x depth x height in cm): 63.5 x 36.0 x 34.0 Outer dimensions (length x depth x height): 70.0 x 42.0 x 51.0 Weight: 10.5 Kg 2-year warranty
