The difference between white crystal and chalcedony is a kind of undirected isomorphism, which is the dehydration product of opal at low temperature or the microcrystalline precipitation generated as an aqueous solution. Because of impurities, the color is complex and changeable. Generally opaque or translucent, transparent when colorless. There is a banded chalcedony called agate, and the opaque chalcedony is called jasper.
In fact, the method of distinguishing crystal from chalcedony is very simple, mainly depending on whether it is crystallized or not. If there is a crystal, it is a crystal. If there is no crystal, it depends. Chalcedony is amorphous without water, and amorphous with water is protein.
Chalcedony can be roughly divided into three types:
First, jasper, jasper is chalcedony with more impurities, opaque and changeable color lines;
Second, agate, agate impurities slightly more, translucent, concentric lines;
Third, chalcedony, chalcedony has few impurities and is translucent.
From the appearance, it is crystal clear, with natural stone particles and cotton body, and the ice powder is slightly better, with ice cracks and no cotton body, which is more transparent. The color of chalcedony is slightly darker than ice powder, which seems to give people a moist feeling, and its beads are opaque.

Chrysotile is green because it contains nickel. It is reported that nickel will form flakes in the minerals like talc. Serpentine containing nickel or other ophiolite containing magnesium and iron, after long-term weathering and laterization, forms chrysotile. In Australia's chrysotile producing areas, these minerals exist with brown goethite and other iron oxides in magnesite-rich soil covered with iron and silicon.
Emerald sapphire from Taiwan Province Province was found in another vein of sapphire from Taiwan Province Province, which can be called the sister stone of sapphire from Taiwan Province Province. Natural blue-green, ice temperature and humidity. Its green, transparent and elegant beauty is almost equivalent to the ice jadeite in Myanmar.
