The opalite host rock of this hand specimen contains several partial Opal nodules. These Opal chunks show no form, of course, and all but one have been broken. The opal is colorless, transparent and quite clear, but shows the faint, milky turbidity that is known as opalescence. Colorful green, blue and red iridescent "fire" is visible in a few of them.
