Jewlery house Tasaki cultivates its own pearls off the coast of Japan. Scroll through to see more images from its farming operation.

A ring, designed by jewelry house Tasaki, featuring five seemingly identical Akoya pearls.

Akoya pearls have an average diameter of 7 to 8 millimeters.

Akoya pearls are often smaller than pearls found elsewhere.

Japanese jeweler Tasaki cultivates around one million Akoya oysters a year.

Pearls occur naturally when an outside agent -- sand or a bone fragment, for instance -- becomes lodged inside a mollusk.

This causes the oysters to secrete an iridescent substance called nacre (commonly known as mother-of-pearl).

In pearl farming, artificial "nuclei" are into growing oysters. Layers of nacre then engulf the object, eventually forming a pearl.

Japanese jewelry house Tasaki has operated a pearl farm in the Kujukushima Islands for over 70 years.

Tasaki cultivates oysters in tens of thousands of nets below the water's surface.
