DESCRIPTION
This image concerns quench crackled quartz, top picture is an imitation for ruby and the bottom one is an imitation for emerald.
Both gemstones were observed on microscope in immersion cell (Benzyl Benzoate) using transmitted diffused light. The picture was taken through the ocular out of loose hand. It clearly shows the advantage of an immersion cell microscope as the dye can be observed as if it was “floating” in liquid, without having the disturbance of facet edges or internal reflections of light in the gemstone.
