Opalite

Opalite is a trade name for synthetic opalised glass and various opal simulants.[1][2] It is also used to promote impure varieties of variously colored common opal.[1] Opalite is sometimes called the Tiffany Stone or Bertrandite. Inside of opalite there appears to be a rainbow. You can read through Opalite, because it is translucent. The streak of opalite (depending on the color) is typically white.
