Genuine naturally occuring turquoise (turquois) is a rare and valuable hydrated copper aluminium phosphate mineral. Due to the opaque blue to green hue of finer grades it has been enjoyed as a gem and ornamental stone for thousands of years. Natural turquoise is a porous stone so stabalising the mineral with resin seals it protecting the natural colour and prevents it from absorbing unwanted elements or drying out .
