Detail closeup of work in progress. Im very excited with how its turning out. It wants to be free and leap off the canvass

Fluorescent blue and green Fluorite
Cubic, gemmy crystals of fluorite on matrix from world famous locality - Rogerly Mine. Medium luster. Fluorite cubes are well coloured - green in artificial light with a strong blue daylight fluorescence, and an even stronger purple-white fluorescence under long wave UV light. This amazing fluorite crystals change colour in different lights - in natural light they are blue, in artificial light they are green. 
Rogerley Mine, United Kingdom
