The cycle of pearl cultivation is very long, and it usually takes 4-6 years or even longer from seedling raising to pearl cultivation to harvest. In addition, during the breeding period, workers need to take care of them very carefully to ensure the healthy growth of the mother shellfish. During the breeding period of 2-3 years, workers must salvage and clean the mother shellfish every 10 to 14 days to remove marine life that may endanger their health, so as to ensure the healthy growth of the mother shellfish.
During the breeding period, the mother shellfish is affected by the water quality and climate, and it is very easy to die besides the water quality. Generally, the survival rate of Pinctada is 50%, and only 40% can form pearls within this ratio. Among them, the roundness of the growth is very good, and there are no flaws. Only 5% of them have no variegated colors and bright colors. And only these 5% high-quality pearls can be made into pearl jewelry, which determines the rarity of pearls.
Pearl processing steps are generally:
1, sorting beads: sorting by different colors.
2, drilling: drilling the pre-selected pearls; When punching a pearl, carefully observe the surface of the pearl, mark the most obvious part of the flower and punch it.
3. Rinse: Use bleaching solution to clean the excess organic matter on the surface, and the formula of rinsing solution used in different colors is slightly different.
4. Polishing: Mix polishing wax in a polishing machine and polish for about 40 minutes.
5. Beading: Beading in different grades according to size, luster, color and shape. How to make a single circle into elegant and beautiful jewelry is very challenging. It still takes a lot of effort to skillfully arrange and carefully connect them into beautiful high-quality pearl jewelry. A string of seemingly ordinary beads requires craftsmen to arrange and adjust the color of pearls countless times before they can be perfectly presented.
