Problems solved by technology

After a period of use, due to abrasion or other human factors, the nacre on the surface of the pearl will be thinned, worn through or peeled off, exposing the bead core under the nacre; because the materials of the bead core and the nacre are different , the appearance of the two is also different, therefore, the exposed bead nucleus will affect the beauty of the pearl
Many of the jewelry made of pearls are used to make pearl necklaces. For a pearl necklace made of multiple pearls, if one of the pearls is damaged, it will affect the value of the entire pearl necklace.
The price of pearl jewelry is relatively high, so it will bring great losses to consumers.
On the other hand, there are many irregularly shaped pearls in the produced freshwater seedless pearls. These pearls cannot be made into pearl ornaments because of their unattractive appearance. They can only be ground into powder for medicinal purposes and added to health products or cosmetics used in , so its value is not very high

Embodiment 1

[0026] Use two-year-old Pinctada martensii with a body length of 7cm and a weight of 30-50 grams as the surgical shellfish. Before the nucleus implantation, the preoperative low-temperature treatment is carried out, that is, 2 days before the operation, it is picked up from the sea and placed in a cold storage or In the freezer, let it cool down in the open air at a low temperature of 8°C-2°C for 1-1.5 hours. Since the female oysters are placed in the sea area under the stimulation of low temperature, they begin to emit sperm and eggs, and they will be discharged the next day. complete. The low-temperature-treated female oysters are placed at room temperature for a buffer period of about 20 minutes before being placed back in the sea for hanging. On the third day, they can be picked up from the sea for visceral sac implantation. The implantation process is required to be completed within five days. Use freshwater pearls to make bead cores of φ7-8mm, use a needle to send the be...

Embodiment 2

[0028] Take the pearl-breeding clam that has been cultured for two years and contains 32 seedless pearls, and carry out preoperative low-temperature treatment before planting the nucleus, that is, 2 days before the operation, pick it up from the sea and put it in the cold storage or In the freezer, let it cool down in the open air at a low temperature of 8°C-2°C for 1-1.5 hours. Since the female oysters are placed in the sea area under the stimulation of low temperature, they begin to discharge sperm and eggs, and the discharge is completed the next day. The low-temperature-treated female oysters are placed at room temperature for a buffer period of about 20 minutes before being placed back in the sea for hanging. On the third day, they can be picked up from the sea for visceral capsule implantation. Collect 10 non-nuclear beads through surgery, and then insert 8 φ6-8mm full nacre bead cores on the nuclear site of the original mantle. Insert the core in March, and you can harves...

Abstract

The invention discloses a full-nacrum nucleated pearl and a quickly cultivation method thereof. The quickly cultivation method comprises the following steps: firstly performing pre-operation low-temperature treatment on nacres to facilitate discharging of sperm eggs; grinding pearls to make pearl nucleuses, inserting the pearl nucleuses into the cores of the nacres, putting the treated nacres in water to be cultivated, and obtaining pearls from the nacres after the pearls are mature, wherein the obtained pearls all are full-nacrum nucleated pearls. According to the full-nacrum nucleated pearl and the quickly cultivation method thereof, the pearls are taken as the pearl nucleuses for producing nucleated pearls, so that the obtained pearls are full-nacrum nucleated pearls from interior to exterior; decorations made by the pearls, which are provided by the invention, are durable in use, and the comprehensive value of the decorations is largely improved; according to the quickly cultivation method, the produced seawater and fresh-water pearls are good in quality, the pearl cultivation period is shortened, the management cost is reduced, the utilization rate of a pool is increased, and compared with the pearls, into which shell-made pearl nucleuses are inserted, the full-nacrum nucleated pearl has the advantage that the economic benefit is improved by 20-50%.

Description

technical field [0001] The invention relates to a full nacre nucleated pearl and a rapid cultivation method thereof. Background technique [0002] Now, in the cultivation of nucleated pearls at home and abroad, what the inserted pearl nucleus generally adopts is the pearl nucleus made from freshwater thick-shell mussel shells, which is used for seawater shellfish or freshwater mussels to cultivate nucleated pearls. At present, the resources of freshwater mussels are less and less, and the price of high-quality pearl cores of grade A and B is very high; while the shells of grade C or below are of poor quality, yellowish in color, and have flat heads, cracks, etc. Defect, if the bead layer of pearl is thin its shortcoming will be exposed, thereby affects the quality of pearl, therefore, the price of the pearl produced with this kind of bead core is low, and economic benefit is poor. In recent years, with the reduction of freshwater thick-shell mussels and the increase in the ...
