Judging from your description and pictures, this is "agate"

Agate is a chalcedony mineral, which is often a banded block mixed with opal and aphanitic. Its hardness is 7-7.5 degrees, its specific gravity is 2.65, and its color is quite layered. Translucent or opaque. Often used as an ornament or ornamental. Agate balls can often be seen in ancient funerary objects. Agate has annular stripes of various colors, and its texture is very similar to that of crystal. Fine without impurities, with glass luster, transparent or translucent multilayer. Each layer overlaps with each other, and there are many patterns such as ripple, concentric, mottled and layered.

Agate has a very long history. About 1 100 million years ago, due to crustal changes, underground magma erupted in large quantities. When lava cools, steam and other gases form bubbles. When the rock freezes, the bubbles are sealed and many holes are formed. After a long time, the pores were immersed in a solution containing silica and condensed into silica gel. Fusible components of iron-bearing rocks enter silica gel, and finally silica crystallizes into agate.

Agate can change people's mood, enhance people's courage and enthusiasm, and give people determination and strength; In addition, it can also strengthen love, promote emotional communication between couples, contribute to the happiness of couples, and exert the most dazzling brilliance.

In addition, it also has medical functions. Traditional Chinese medicine believes that agate is cool and nontoxic, and grinding agate chips can be used for eye diseases. Improve human endocrine system, strengthen human metabolism, enhance blood circulation and enhance human immune function.

Maintenance method:

First of all, be careful not to collide with or fall off hard objects. When not in use, it should be stored in a soft jewelry box. Try to avoid contact with perfume, chemical solution, soap or human sweat to avoid erosion and affect the brilliance of agate.

Secondly, we should pay attention to avoid heat sources, such as sunlight and stoves. Because agate will expand when heated, the molecular gap will increase, which will affect the quality of jade, and continuous contact with high temperature will also lead to agate explosion.

Agate is generally placed as far as possible to avoid sunlight, and often wiped to keep it clean. If possible, you can occasionally add pure water to keep it moist, which will be more beautiful. When not wearing small ornaments, it is best to put them in a dark and humid place, and the storage environment close to the original ecology of agate is the best. In particular, water bile agate has natural water during its formation. If the surrounding environment is very dry now, it will cause the evaporation of natural water, thus losing artistic and economic value.
