A cabinet sized specimen of teal blue Cavansite crystals on a Stilbite matrix. The crystals have a good luster and well defined spheres, even showing an acicular fan section.
 
COLOR NOTE: The proper color for this specimen is out of gamut for current screen display technology, it is a teal color that cameras can't properly represent. The saturation is accurate, but the color is slightly shifted into the green spectrum.
 
Measurements: 10.9 x 6.9 x 8 cm.
