Every people loves the pear because of its mysterious charm. However, the natural resources of pearl run out gradually. People begin to cultivate pearl in order to keep its value. At the same time, the experts constantly improve the technology of cultivating to gain better quality. The man-made pearl is mainly born in mussels. Then how to raise pearl mussels?
Actually, the mussels are easily raised by people. They only need a environment of clear water. The producers usually place a layer of sands in the bottom of water. When we look at the sunny water, we wonder how the pearl mussels live in the beautiful world of water? The sands are important for mussels to live, so we can often see them at seaside. However, it is not easy for professionals to cultivate pearl. In complicated processes of cultivation, the worker must have advanced skills and rich experiences.
Why does the mussel stay at sands silently? Why does not it walk around? Because its ability of crawling is too weak. When you see the shallow track it left, you will know its hard trip. The mussels are growing up just like this trip day by day. You would find that a charming and nobler pearl is born in its body someday.
Then why can the pearl grow in mussels? There is a interesting legend in ancient India. When the oyster shell opens, a drip of rain happens to fall into shell and become a bright pearl. In fact, the pearl is formed by bug, grit and the other strange things. These things fall into shells occasionally and become a pearl sac. The pearl sacs continue to secrete pearl nacre and surround itself. After a long time, the pearl is formed.
There are abundant resources of rivers and lakes in China. These rich resources provide excellent environments for cultivating pearl. Although the development of pearl is later in China, the diligent experts have made a great progress in this field. Now most productions of pearl are from China. The pearl industry is booming increasingly.
