General Information
Turquoise's colour ranges from sky blue to green. The finest colour is
an intense deep-blue azure, rarely seen. The intensity and evenness of
colour are important valuation factors. So too is the quality of the
polish. "Robin's egg blue" is another highly valued colour.
Howlite is often dyed to imitate turquoise. Turquoise made in a
laboratory has a very uniform colour. Chalky varieties of turquoise are
often coated with wax or oil to enhance colour - and when treated like
this, the colour change is not permanent.
Turquoise is often fracture sealed. This doesn't mean that it has
fractures, it means that it was sealed with an acrylic resin to enhance
it's colour, texture, and hardness.
Turquoise is somewhat soft so avoid scratches and sharp blows. To be
certain and coatings are not removed also avoid hot water and household
chemicals.
