My system is not decent

A long time ago, Dulan Mountain in the eastern coastal range of Baodao used to be a volcano.

After the volcanic eruption, magma containing a large number of chemical components was continuously deposited here, laying the material foundation for the formation of blue chalcedony.

In addition to Baodao, blue chalcedony has also been found in Chouguo, Zhiguo and other places, but good quality blue chalcedony is mainly concentrated in Baodao in my country.

There are as many as 12 varieties of blue chalcedony in my country's Baodao. Among them, sky blue, emerald blue and sea blue are the three varieties that are expensive and of high quality.

These are calculated in carats and the prices are very high.

As one of the most precious gemstones produced in the coastal mountains, Baodao blue chalcedony is rich in color and bright in color, and has been favored by many international jewelry brands.

In history, the Duke of Windsor, who is famous for "only loving beautiful women and not Jiangshan", once gave his wife a set of blue chalcedony jewelry.

In the early days, Taiwan's blue chalcedony was mainly exported, and most of them were sold to neon and other places.

In recent years, due to the increasing demand for Baodao sapphire, the market has been in short supply.

As a result, some Baodao businessmen began to import sapphire from Chouguo, Indonesia and other places for processing, resulting in a large number of imitations on the market, and the price was much lower than the real Baodao sapphire.

Due to the large output of Baodao Sapphire, it does not have collection value.

Therefore, friends who want to go to Baodao to buy blue chalcedony, if it is only for daily wear, there is no need to choose overpriced blue chalcedony.

Also, chalcedony generally needs maintenance, especially some precious chalcedony.

When maintaining Baodao blue chalcedony, avoid high temperatures.

If the temperature is too high, this blue chalcedony will change color. Once the color changes, it will be difficult to return to the original color and lose its own value.

In addition to the most precious blue chalcedony, there are many chalcedony produced in Baodao, which are very precious.

For example, the white chalcedony among them is the rarest and therefore the most precious.

There is also chrysoprase, a fibrous quartz that contains nickel and is usually apple green.

The green color is caused by hydrous nickel silicate, which will fade when exposed to high temperature or constant sunlight.

Because the output of green chrysoprase is low and the color is attractive, it is often used by unscrupulous traders to pretend to be jadeite or emerald.

However, it can also be seen from this how beautiful this kind of chrysoprase is.

Some of them are genuine, such as blue chalcedony, also called emerald sapphire.

But this is not sapphire, nor emerald, it belongs to blue agate according to its composition.

Friends who travel to Baodao, don’t be fooled by this name, because its value is far less than that of sapphire.

Generally speaking, the Baodao chalcedony series all belong to the agate series, which can be judged from its density and structure.

Although the total output is not high, it has a certain collection value, but its value is far from that of emeralds and gems.

In fact, the most famous red coral in Baodao should be the red coral, among which the ox blood red coral is the best.

There is a famous coral story in the history of our country, which tells the legend of a rich man Shi Chong fighting for wealth during the period of Emperor Wu of Jin Dynasty.

As a result, Hu Kui in the Yuan Dynasty wrote a poem telling us how Shi Chong fought for wealth.

The iron net is a bottomless valley, once it is placed in the golden house, the rich son of the Shi family does not know the treasure, and a wishful blow is like flying dust.How can it be like the flat peach tree in Langyuan, with one flower and one stone three thousand springs.

Red coral is the most vivid of the organic gemstones and is harvested from the deep sea.

Its colors are divided into white, cyan, black, orange red, pink, meat pink, pepper, red bull, blood red and so on, among which the bull blood red is the best.

The color of coral is different because it contains different impurities, and it is red because it contains 1% trivalent iron oxide.

As the saying goes, "thousand-year coral is red for thousands of years". Coral is the only living thing in jewelry for a thousand years. It is listed as the three major organic gemstones together with pearls and amber.

It is formed by the accumulation of coral polyps, and is listed as one of the seven treasures in Eastern Buddhist scriptures.

Red coral has extremely strict requirements for the growth environment and sea area.

The distribution in the world is not extensive, mainly concentrated in the waters of my country's Wanwan, Nannan Island, the surrounding waters of the Hawaiian Islands, the waters of Midway Island, and the southern waters of the Italian Peninsula in the Mediterranean Sea.

Among them, Baodao is the main producing area of ​​red coral in the world. In its heyday, there were nearly 300 kinds of red coral, and its output accounted for about 80% of the world's output.

Because of its good quality and unique shape, it is dubbed the "Coral Kingdom".

Although the output of Bent Coral is very high, its history is very short, from the development and utilization to the present, only 60 years of history.

In the early days, before the red corals of Baodao were discovered, the origins of red corals at that time were mainly concentrated in Europe.

For example, Indians believe that precious coral is the mother of the earth;

In the European royal family, red coral has become a symbol of people's identity and status;

In our country, when some officials went to court in the Qing Dynasty, the beads they wore were also made of red coral.

In 1874, red coral was discovered in the neon sea.

The red coral there is rich in color and has a strong jade texture.

The locals call it Aka, which means red, and use advanced processing technology to make red coral into handicrafts, sell them overseas, and vigorously develop the coral industry.

In 1923, red coral was also discovered in the Wanwan sea area of ​​my country.

At first, the local people didn't realize that it was a treasure in the sea, and it was fished by fishing boats from Neon.

After the end of World War II, the local fishermen became alert, but more than half of the precious red corals have been caught by the neon.

In 1964, Baodao began to vigorously develop the red coral industry. This area is mainly rich in two kinds of red corals, MOMO and AKA.

However, due to the lack of knowledge and the limitation of processing level, most of the local people mainly sell unprocessed red coral raw branches directly, and the price is much lower than the price of selling finished products.

Later, through the continuous introduction of foreign advanced technology, further processing and carving of red coral was carried out, and the price has been greatly increased.

At present, 99% of red coral products are exported.

Due to unrestrained and wanton development, the ecological environment of the ocean has been seriously damaged.

In order to further regulate the mining of red coral, the relevant local departments have introduced policies to divide the sea area into five areas of ABCDE.

At present, only the second area is open, and fishing boats can only fish in the specified sea area, so as to control the exploitation of red coral.

In recent years, due to oversupply, the price of red coral in Baodao has also shown a trend of rising, with an increase of as high as 40%-60%.

Even so, it still cannot dispel the enthusiasm of foreign tourists to buy red coral.

Baodao Red Coral has gradually developed into a local iconic business card.

They also established the only red coral-themed museum in the world: Wanwan Red Coral Museum, which is used to collect various precious red corals.
