However, with the agate mineral deposits being discovered in large quantities around the world, agate is no longer a rarity. Due to the unrestricted and disorderly mining of the agate deposit, the distribution of jewelry processing is widespread, and the price presents a vicious competition in the market environment. In the past two years, the price has dropped to the bottom. With the devaluation of the currency and the increase in prices, prices are still rebounding, but the price still remains. Very cheap. Although most of the color agate on the market is currently warmed and burned, manual optimization of the burn color is the default industry practice and universal procedure in the jewellery industry, because naturally good color agate is rare, mostly white or gray, natural Red agate is rare, natural green agate less, but also not burning green, can only stain, 99% of all green agate on the market are dyed, green bracelets wear for a long time will fade, is said to wear on the body Harmless to the body!

As we all know, everything is like this. The same thing has both quality and defective products.

A few days ago, I went to visit China’s Jewel City in Changle, Shandong. The price of an agate bracelet was between 40 and 60 yuan. I saw a pair of agate bracelets with better colors. The boss asked for 1,600 yuan. I also The price of 500 yuan has not been traded, and the final price increase to 760 yuan, businesses have to 800 yuan, I simply do not, and choose another home. Regardless of the optimization, the common ones in the small shops are not good agates. The real good agates are reserved by the big customers and are rarely found in small shops. A piece of a few hundred yuan good agate material carved ornaments, and some can be sold for more than 10,000 yuan.

Agate is one of China's traditional jewels. China is a country rich in agate, and its texture is also significantly better than agate produced in Brazil and other places. In many people's eyes, the pearl agate is a symbol of wealth. Jade and agate are crystal clear, beautiful patterns, colorful, but similar in nature, the average consumer is difficult to tell the truth. What's more, is the agate with a long history a stone or jade? In the historical literature, "Red Jade" and "Fire Jade" refer to ruby ​​or red agate? These historical issues remain very controversial. Thousand kinds of agate 10,000 kinds of jade, there are many types of agate, there are mountain agate, water agate, etc., the color is also very rich. Agate has many colors, such as red, white, yellow, blue, black, purple, green, gray, brown, but with three colors of red, white, and black. There are also patterns such as silk. Among them, red agate is known as the top grade, so in the "Gugao theory" in the "Agate is not red, a poor," said. The texture of the agate is like crystal, delicate and without impurities, glossy glassy, ​​transparent or translucent. It is mostly lamellar. Each layer overlaps with each other and forms a variety of patterns such as corrugated, concentric, mottled, lamellar, and so on. Agate is jade or stone? This controversy lasted for 1500 years in China. After the Ming Dynasty, it was gradually accepted as a raw material for jade. However, some of its mysterious veils have not yet been fully revealed. Most people still think that agate is broadly defined. Jade believes that agate is a jadeite crystal mineral. Although it has the texture of jade, it is not real jade. As far as its status is concerned, it is at best a mid-range "Yu-Yu." Some businesses advocate it as a high-grade jade material, which is purely a flamboyant consumer nonsense!

Agate is a type of jade that is mainly composed of cryptocrystalline quartz (chalcedony) and is called “Qiongyu” in ancient times. Its formation is due to changes in the earth's crust during the ancient times. Underground magma was ejected. During the process of cooling and consolidation of lava, bubbles formed by steam were enclosed and formed caves. After several years, the silica-containing solution penetrated into the bubbles and condensed into silica gel. Soluble components such as iron-bearing rocks diffuse into the silica gel. Finally, with the loss of water, the silica crystals become agate. Because the soluble components such as iron-containing rocks diffuse into the silica gel, the color of the agate becomes colorful, and the color and pattern are beautiful. It is often used to make jewelry, carving pieces and other crafts. It is known as one of the seven treasures and is the stone of longevity. It is deeply loved by people.
