5.6" Free-Standing, Polished Crazy Lace Rosetta Stone - Mexico
This is a free-standing, 5.6" wide, polished section of crazy lace rosetta stone, also known as rosetta jasper. The colors vary throughout this specimen, ranging between pink, red, peach and white.
Crazy lace agate, also known as Mexican Agate is a unique banded agate that comes from Chihuahua Mexico. It gets its name from complex, lacy patterns swirling through the stone. Colors can vary from creme to orange, to red colorations and are due to iron and aluminum inclusions in the agate.
Jasper is a term that can be applied to an opaque variety of chalcedony (light does not pass through it). The opaqueness is due to a higher concentration of impurities mixed with silica/quartz. Like agate it may form in a wide variety of colors, and is often multi-colored. In most cases, jasper will occur when silica-rich fluids permeate throughout a soft sediment or volcanic debris deposit. The fluids then crystallize around the particles/impurities, resulting in a cementation process. Most often, the impurities present determine the coloration of the deposit following solidification, however other factors can play a role in the color of what is now considered a jasper.
