925 silver bracelets A wide variety of agate

Agate is one of the more common colored gemstones in jewelry, with many varieties and colors.

Agate refers to chalcedony with a banded structure. It is a colloidal mineral whose main component is silicon dioxide. The word “ágata” is derived from Buddhist scriptures. The original name in Sanskrit isAsma Gabo”, o que significa “horse brain.The ancients misunderstood thehorse brain alabasterbecause they did not understand the cause of the agate pattern.

Before the Han Dynasty, agate was calledQiongyu” e “Red Jade”, which actually refers to the current red agate.

What is the difference between agate and chalcedony?

The mineral composition of agate is mainly chalcedony, sometimes containing a small amount of opal and fine quartz, which is a striated cryptocrystalline block. If the block has no striated structure, it is chalcedony. Some people call the ordinary chalcedony with the unlined belt structure also called agate, which is a misnomer.

Both agate and chalcedony should be white (or colorless), and gray, marrom, vermelho, azul, green, black and other colors will appear due to the presence of pigment ions or other impurities.

What is the relationship between the color of agate and its value?

The color of agate has a great relationship with its value. Por exemplo, blood red agate belongs to high-quality agate. “Agate is not red for one life is poor” (this term originally comes fromGe Gu Yao Lun”), this is a mantra in the jade carving industry; blue agate is also high-quality agate; black flower agate refers to the contrast of two or more colors of black and white The strong agate, which is used to cut pandas and other animals, is very popular.

White agate has a large output, but it has few technical uses. It is mostly used to make instruments, bearings, balance knives or mortars. But since the new artificial dyeing process, the status of pure white agate has greatly improved, and the demand is also increasing.
