Colour Filters, Spectroscopes and Dichroscopes
Colour in gemstones is a considerable part of their beauty and value and it is often a big clue as to what a gemstone might be. However, sometimes colour can be misleading! The colour, or lack of colour that we perceive, is the result of many different contributing factors. These tools will help you to quickly separate similarly coloured materials and add evidence to your gemstone identification workings.
