There are two broad classes of Opal: precious and common.
Precious Opal displays play-of-color
(iridescence);
common Opal does not. Play-of-color is defined as "a pseudo
chromatic optical effect resulting in flashes of
colored light
from certain minerals, as they are turned in white
light." The internal structure of precious Opal
causes it to
diffract light, resulting in play-of-color. Depending
on the conditions in which it formed, Opal may be
transparent,
translucent or opaque, and the background color may be
white, black, or nearly any color of the visual
spectrum. Black
Opal is considered rarest, whereas white, gray, and
green are the most common
