One, Gobi agate, mainly produced in Gobi areas such as Alxa, Xinjiang and Outer Mongolia. Probably the formation time can be traced back to 150 to 300 million years ago. The product of submarine volcanic eruption and rapid cooling, experienced seawater erosion, weathered rain and snow, hot summer, and severe cold after the erosion of the geological landscape. Gobi Agate is a stunning and convincing collection of "shape, texture, color, texture, and flavor". The beautiful shape and rich colors of Gobi agate are irreplaceable and unique among all gems and jade. It is a new gem product discovered and confirmed in the past two years. It has a small output and is extremely scarce. It is a precious and non-renewable resource. It has extremely high appreciation potential and artistic value, and has been recommended by various media. It is expected that there will be great appreciation potential in the future.
2. The so-called desert paint is the bare desert area of the Gobi bedrock. Due to the rise of groundwater, a layer of red-brown iron oxide and iron oxide are often left on the surface of the stone after evaporation. The black manganese oxide film is like a layer of paint, hence the name desert paint. The ornamental value and collection value of desert lacquer should be those with beautiful pictures and vivid shapes; in terms of stone quality, the harder the carrier rock, the higher the collection value. Desert paint is not uncommon, but it is rare to see that the pictures are peculiar and novel. It is similar to the model tree stone. It is better to paint on hard rock. If it can be wrapped by transparent minerals or rocks such as agate and opal, it will be a superb product and doubled in value. The discovery of desert lacquer was described by Du Wan in Song Dynasty's "Stone Book of the Clouds". Following the grape agate, the desert paint in the Gobi stone has been recognized and respected by the international stone-appreciation circle, with great potential for appreciation. The high-quality desert paint has high collection value, and quite a few have been collected by collectors in Japan, the United States, Taiwan, Australia, and Southeast Asia.

Fourth, Gobi jade: Mohs hardness 6.5-7.2, translucent, common uniform transition of yellow, white and red. There are two types of Gobi pebbles and wind-edge Gobi jade. Gobi pebbles are round in shape, large in volume, smooth in stone skin, strong in texture, and scattered with desert paint. Some pebbles are dotted with black textures or patches to form patterns, fine in texture and color. The positive and full-form jade is the top grade; the wind-edge Gobi jade is a typical wind-eroded ornamental stone, mostly in the shape of sub-edge or sub-circular, with rigid wheel lines, single color rhyme, strong jade texture, and typical wind-eroded edge characteristics. There are single-sided, double-sided and multi-sided. The volume is small, and it is mainly for quality rewards, and the ornamental value is not high. This type of stone has a good texture, but it is not easy to form. Nowadays, it is mostly used for processing carvings. The quality and color are not inferior to Yunnan Huanglongyu. Near the Xiazigai Oilfield, there is a crystal or chalcedony-like Gobi jade. It is crystal clear and bright in color. It will transmit a strong light under sunlight. The local stone friends call it "Gem Light". It is small in size and is Gobi. Rare varieties of jade
Five, mud and stone. Most of the Gobi mudstones are produced in the vast Gobi Desert in Xinjiang.
