This is the start of the nucleus insertion process.

Yamashita-Pearl provides an integrated service from cultivation to design and sales!

Needless to say, aquaculture is an important task.

Among them, the ball insertion (nucleus insertion) that starts at this time is a very skilled task.

This affects the quality of the pearl.

Nucleus insertion is the process of gently inserting cells and nuclei into the ovary using a scalpel.

This requires delicate technique to avoid damaging the nerves, muscles, and intestines that are attached to the ovaries.

First, as a preparation

Beforehand, a plug is inserted into the mother shell to keep it open.

This is the preparation of the cell fragment to be placed with the nucleus.

The string-like mantle is divided into 15 to 20 pieces.

This mantle secretes the components of the shell.

By putting these cell fragments and nuclei together,

The nacre forms around the nucleus to create a pearl.

This is where the nuclei and cells are put into the ovaries.

(The thing in the silver cup in front of me is the core.)

The surface tension of the water is used to attach the nucleus to the instrument and transport it quickly to the ovary.

It's a very skilled job and it takes several years to become a fully-fledged professional.

The mother shells with their nuclei inside are neatly lined up and left to rest in the calm ocean.

After this, it takes about eight months for the pearls to be harvested.

Removing barnacles and seaweed from the surface,

It requires a lot of daily work and management.

To deliver beautiful pearls to everyone

I'll do my best!!
