In this episode of the Facet nation gemmology podcast, Lucinda and Simon explore the intricate world of colour in gemstones. They discuss the significance of colour in determining the value of gemstones, the science of light and how it interacts with materials to create colour, and the chemical elements responsible for these hues. The conversation also covers the colour wheel and its relevance to gemstones, the methods of analysing gemstones through spectroscopy, and the perception of colour. The episode concludes with a teaser for future discussions on more complex topics related to colour in gemmology.
