This polished free form cut Fire Agate cabochon preform measures 17 x 13 x 8 mm, weighs 17.0 carats and has a nice multi-colored fire. This is a dark fire agate gem that requires strong light to reflect all colors in its multicolored spectrum and it also has a small amount of matrix showing on the bottom of the stone. It could be trimmed down into a smaller higher quality stone with very little effort and time, or used as-is for jewelry purposes or gemstone collection specimen display purposes. Gem Grade: CC
The gem originates from Slaughter Mountain, Arizona, which is known for fire agates with intense color variations from vivid reds and oranges to intense greens, purples and blues. Photographs were taken indoors under lights and outdoors in sunlight while the gem was dry and to best display the internal fire.
The colors found within fire agates are created by the Schiller effect, as found in mother-of-pearl and opals. It is caused by the alternating silica and iron oxide layers which diffract and allow light to pass which forms the interference of colors known as fire. This play of color requires good lighting for best fire display and the gems will appear darker in low light conditions.
