taken when polishing and setting opals. Despite their hardness, they are prone to crazing and
cracking. To prevent this, opals are normally stored in moist cotton wool or cloth.

a very uniform color. Chalky varieties of turquoise are often coated with wax or oil to
enhance color - and when treated like this, the color 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 color, 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.
