COLOUR

Colour could be the most important factor to characterize different gemstones. There is no doubt that gemstones with more attractive colours, are more valuable and the ones who are rare, are more popular, valuable and expensive.

Actually, gemstone colours occur in 2 ways; some gemstones have a specific colour in their structure, like peridot, and some are colourless in their pure character but they are coloured by colouring elements, like Sapphire.
