STONE WITH NATURAL GRAIN
Natural grain stone is the rock of natural earth after piled over 350 Million years. It not only
includes earth ingredients good to human body, but its appearance and the modeling is
also unusual, therefore it is called loess jade. The rock is also called natural stone or wood
grain stone for its color and the modeling are magnificent and changeable.
By analyzing and comparing the average fossil ingredient of the rock, the natural grain stone,
as one of the igneous rock, it can be regarded as one kind of ultra basic rocks close to peridotite.
The main ingredient of the ore is mainly loess. As bluish gray color diaschistite rock, the lower part
of which is mainly natural grain rock (igneous rock).
The chemical composition of natural grain stone is listed below for reference (Table 1). It not
only contains ingredients good to human body, but also contains elements deciding the hardness
degree such as Sio2, A1203, K20, Mg0, and Ca0. As a kind of stone material, its outstanding basic
physical property (Table II) are also worth for affirmation.

Natural grain stone was believed to have the function to mediate bad qi from the human body and
to realize ones dream even in the early time. Even though these have not been proved by scientific
data, natural grain stone is a kind of precious and, mystical gem is a common knowledge. In fact,
the remote infrared ray specific emissivity, natural anion formation rate, antibacterial effect, and
air sweetening function all have already passed tests of all relating authorities. (Please refer to
Appendix Test Reports), and is authenticated as the natural stone with highest healthy function.
Natural grain stone is a high-quality building materials processed from the raw materials with top
technology. With unique outward appearance, color, and healthy function, it is a kind of upscale
construction stone material which the natural stone material is unable to compare. At the same
time, the mystical astronomy has permanent emission that may protect the family members' health.
