Turquoise is a soft gemstone and it is a standard practice to impregnate/stabilise it for it to be more suitable for everyday wear. This process does not change the colour of the stone and the gemstone retains its original colour. Completely raw Turquoise can turn dark/black in colour due to oils and other substances coming into contact with it during wear.
