As a kind of pure cobble stone from experienced million years ago, the crustal movement produced by the ancient riverbed uplift after the sand in the mountains, experiencing the flash floods hit, handling continuous extrusion, friction. In the process of evolution of tens of thousands of years vicissitudes of life, they hit the water weather-beaten wave motion, gravel collision friction lost irregular edges, and sediment was buried along the silent millions of years. Pebbles main chemical composition is sio2, followed by small amounts of iron and manganese trace of copper, aluminum, magnesium, such elements and compounds. They have different pigment, such as iron, sand for blue purple copper, manganese, yellow for for silica gel stone translucent jade color with green, mineral, etc, Because these pigment ions into the silica hydrothermal type and content, thus showing different shades of color depth, ever-changing pebbles show black, white, yellow, red, blackish green color, walked.
