The pearl breeding cycle is very long. Generally, it takes 4-6 years or even longer from seedling breeding to pearl breeding to harvest. Moreover, during the breeding period, workers also need to take very careful care to ensure the healthy growth of female shellfish. During this 2-3-year breeding period, workers must salvage female shellfish for cleaning every 10 to 14 days to remove marine organisms that may endanger their health, so as to ensure the healthy growth of female shellfish.
During the cultivation period, female shellfish are affected by water quality and climate. In addition to being affected by water quality, they are very easy to die. Generally, the survival rate of pearl oysters is 50%, and only 40% of them can form beads within this proportion range. Among them, the roundness of growth is very good, flawless, no mottled, and the color is gorgeous, but 5%. And only this 5% of high-quality pearls can be selected for pearl jewelry, which determines the rarity of pearls.
The first thing is to stay away from these kitchen fumes. Pearls have many tiny pores on their surface. To prevent the pearls from inhaling these dirty things, we must stay away from the kitchen and not bring the pearl necklace into the kitchen, especially those kitchens with a lot of grease and smoke. If we must bring them into the kitchen, then we have to be more careful in the kitchen. When cooking, we should take off this beautiful pearl jewelry. Steam and lamp oil may penetrate into our jewelry and make it yellow. After each time you wear your pearls, make sure to wipe them clean and put them in their own box.
After wearing them, it is best to wipe them with a parchment or fine velvet cloth. Do not use the kind of tissue paper, because some of them are very hard and rubbing with such tissue paper may wear them. Never use water to clean your pearl necklace because water can get into the small holes of the pearls and it is difficult to clean them with facecloth. The water may ferment in the pearls and the pearl strands will turn green.
When cleaning pearls, use soft paper or cloth containing silicone oil to wipe them. For blackened, lusterless and badly tarnished pearls, soak them in 20% salt water for 1 hour and then in water for 10 minutes.
pearls should not be exposed to sunlight, moisture, or stored with hygienic balls and camphor. Pearls are afraid of acid, sweat, perfume, hairspray and other ingredients, so it is best to wear them through clothing. Wear makeup before wearing pearl jewelry, as most beauty products are harmful to pearls, including perfumes and hairsprays.
