A faceted pale yellow Scapolite from Dodoma, Tanzania with a series of parallel rows of dotted inclusions running through the stone at angles which follow the crystals growth.

The tightly spaced inclusions,
believed to be Magnetite, serve as a diffraction grating, causing a vivid iridescent display which is clearly seen as the stone is rotated in hand. This unique effect gives rise to the term "Rainbow Scapolite" being used by some gem enthusiasts to describe these unusual gemstones.

Image 5 is a magnified view of the iridescent inclusions displaying a spectrum of iridescent colours.
