The pearls are so sharp! About the size

We're talking about size here.

Size refers to the diameter of a pearl in millimeters and is divided into 0.5mm increments. Therefore, 8.0mm refers to beads with a diameter of 8.0 to 8.4mm.

Beads smaller than 6 mm are called baby pearls, and among baby pearls smaller than 4 mm, the kernel size used in the shell is less than 9 rin (approximately 2.7 mm), so they are called ``Rindama'' (Rindama). There is also.

Basically, the bigger the price! ! ! ! !


This is because the production cost is high and it is rare.

I believe there are two ways to grow large pearls.

The first method is to purchase large Akoya shellfish and add a large core.

Large Akoya shellfish that can be aimed at 9mm or more are twice as expensive as Akoya shellfish that are aimed at 8mm, and the price difference for cores is 1.5 to 2 times as much. And above all, technology is required. It also places a heavy burden on the Akoya shellfish, resulting in a high mortality rate.

The second method is to grow it for a long period of time.

If you raise a shellfish aiming for 8mm or 8.5mm for a long period of time, the shellfish will continue to grow pearls throughout its life. There is also a risk that the shellfish may die during the process, or the shellfish may become damaged due to stress, or the shell may lose its shell.

From the above, it can be concluded that there are certain risks involved in growing large pearls. This is what is called high risk and high return.

This means that although large-sized pearls are expensive, they are worth the price.
