Chatoyance

 Chatoyancy  or chatoyance, is an optical reflectance effect seen in certain gemstones Coined from the French "oeil de chat", meaning "cat's eye", chatoyancy rises either from the fibrous structure of a material, as in tiger eye quartz, or from fibrous inclusions or cavities within the stone, as in cat's eye chrysoberyl The effect can be likened to the sheen off a spool of silk: the luminous streak of reflected light is always perpendicular to the direction of the fibres. For a gemstone to show this effect best it must be cut  cabochon, with the fibers or fibrous structures parallel to the base of the finished stone. Faceted stones are less likely to show the effect well.

Opalite is an opalized volcanic tuff or ash that may occur with common opal
 and agate. It may be dendritic. The key distinction between opalite
 and common opal is that opalite is very hard; specimens of opalite
 saw or chip with difficulty, whereas opal is commonly glassy and
 chips easily Opalite may have a wet appearance upon breaking fresh
 specimens creating the illusion of opal. Because of its hardness,
 opalite will commonly be found in pronounced outcrops or ridges in
 localities in the Mojave Desert and other world wide localities,
while common opal outcrops form muddy, rolling hills or colored soil  (laterites?). Common opal fractures readily into tiny crumbs upon
 hitting with a rock hammer and opalite does not.

Opalite probably has a hardness of five to six
. Opalite appears to decompose into sand,
 while common opal appears to decompose into a clay or mud (expansive
 clay). Opalite is associated with deep beds of volcanic ash or
 welded ash flow tuff, so it may occur with deposits of fossil palm
 root, palm wood, and bog . Opalite is
 often associated with moss agate and plume agate. Opalite can be a
 variety of colors, including white, tan, brown, green, and peach.
 Opal has a brittle fracture to it, while opalite does not exhibit
 this property.
