A smoky coloured Scapolite cabochon from Dodoma, Tanzania with parallel rows of dotted inclusions running through the stone.

The tightly spaced magnetite inclusions serve as a diffraction grating, causing an iridescent display which is can be seen seen against the dark background colour of the stone as it 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 4 displays the iridescent inclusion scene under microscopic magnification.

A visually stunning gem of fine quality for collectors and jewel designers alike.
