A large fantasy rock with nice, deep tenebrescence on one side.
The main minerals on this large specimen are tugtupite (cherry red SW), along with chkalovite (the rarer pearly white variety – a classic example of how tugtupite replaces chkalovite), blue analcime, orange sodalite and black arfvedsonite throughout the matrix. On one side, green chkalovite displays as a coating on the sodalite. Under LW both the tugtupite fluoresces a bright orange (more salmon for the tugtupite). The delicate veining on this material clearly illustrates tugtupite replacing chkalovite and offers up fascinating patterns.
Very unique material.
The nickname “Fantasy Rock” encompasses a group of rocks found on the Taseq Slope in the Ilimaussaq Complex, Greenland and only in this one locality within the complex. A typical Fantasy Rock usually consists of four basic minerals: tugtupite, sodalite, chkalovite, analcime, and they are always the most color-rich pieces from this exotic, remote locale.

Minerals which are capable of this reversible color change by exposure to UV (or other energy sources), without any change in their essential composition, are said to be tenebrescent
