Young and ancient gemstones in the mining area within 20 years or will be exhausted
There is an organic gem that you must know, but you may not be familiar with it, that is the spotted stone. One of the organic bio-gems (pearls, ambers, corals, etc., also known as organic gemstones) is the fossilized shell of Nautilus 70 million years ago. It has only been discovered as one of the important gemstones in the last 50 years. Spotted stone, you can say that it is very old, because it was active on this earth at the same time as the dinosaur, and disappeared mysteriously with the dinosaur; you can also say that it is very young, because it was not until 1990 that it was world jewelry. The Federation officially confirmed that it is a new type of gemstone, and started commercial mining and sales in the true sense. The young gemstone family also has one youngest member. The name of Ammonite comes from the ancient Egyptian sun god Ammon, which is said to be shaped like a spiral horn of the god's head. Although the fossils of nautilus are all over the world, the most distinctive and brilliant is the gem-quality porphyry stone produced in southern Canada. 7500-70 million years ago, the spotted stone production area was once a warm shallow sea. There are a lot of various nautilus in the sea. Due to the frequent orogeny of the Rocky Mountains, the volcano often erupts, often several meters thick. The volcanic ash fell on the surface of the sea, causing a large number of creatures in the shallow sea to die quickly and be buried. Over time, the volcanic ash in the area is four kilometers thick. With the subsequent crustal movement, the strata in the shallow sea area gradually returned to the position close to the ground. The nautilus that was buried deep in the past evolved into the world's only snail fossil, the snail stone, because of the enrichment of iron, magnesium and volcanic ash. Despite all the vicissitudes of life, the unique geological conditions here preserve the characteristics of the zebra stone and transform it into a truly gem-quality jewel of commercial value. The Bearpaw Shale Formation in southern Alberta, Canada, is the only region in the world that can mine high-quality variegated stones. Hundreds of years ago, locals living on the banks of the St. Mary River accidentally found several colored stones in the rock formations. This kind of stone can emit colorful light under the sunlight. If the stone is turned, its color will change with it, which is very strange. At that time, people thought that this stone absorbed the essence of the heavens and the earth, and had magical power, so they were worn as "amulets". It is no wonder that the spotted stone will become the national stone of Canada, because the world can only find its colorful trails in a small piece of land in southern Canada. Each piece of glazed stone contains many layers, you can think of it as a book, bound by many pages. When the sun shines on different levels, "diffraction" (a physical phenomenon that deviates from the original straight line when the light wave encounters an obstacle) occurs in different colors. Since the number of layers of each porphyry stone is different, the pressure of the overlying rock layer is not uniform when it is formed underground, so the cracks on the surface layer are also unique, so that each glazed stone has different colors. Texture, pattern and texture, each spotted stone is unique. There are quite a few differences between the spotted stone and other parts of the world with slight smudges but monotonous colors (mostly brown). The price is a hundred times different. Please pay attention to the screening, such as another one produced in Madagascar. The fossils of small ammonites will also have a small amount of color change on the yellow background. Many merchants will claim that such fossils are also colored stones, but in fact, this level of fossils is far away from the spotted gemstones, not only The output is much larger, and the difference in aesthetics and value is also huge. The color stone has the difference of pure natural, laminated and sandwich stone. The price is arranged from high to low. The weak texture needs the protection of the crystal film to avoid the damage. Usually the regular shape of the small particle spotted stone is covered by the film. Processed and then used for mosaic. The natural color spots that can be seen on the market are few and far between, usually irregular and large, and the price is high. In addition, the current ore mining method is similar to that of open-pit coal mining. People use excavators to directly strip the overburden, which will cause great damage to the local ecological environment. Therefore, the mining of ore is strictly restricted in the local area, so the real mining The number of spotted stones is extremely small, and complete fossil specimens are rare. Some experts estimate that if the current mining speed, Canada's spotted stone mining area will be exhausted in about 20 years. If the new production area cannot be found in the future, the spotted stone will be "extinct again."
