Kyocera's
Jewelry
50th Anniversary

It all started with a single lab-grown colored stone.

In the 1970s, against a backdrop of soaring gemstone prices and declining quality,
Kyocera's founder, Kazuo Inamori, became concerned that the true allure of gemstones—
to inspire dreams and enrich the human heart—was being forgotten. This led him to
embark on the challenge of growing the highest-quality emeralds through
recrystallization.

This year, 50 years have passed since the birth of Crescent Vert.
Through a wide variety of gemstones, thankfully, we have met many treasured customers.
While cherishing our gratitude toward our customers, we will continue to refine our
"jewelry that enriches the human heart."

About Crescent Vert

Crescent Vert lab-grown colored gemstones are a crystallization of the same transparency and vivid colors of natural gemstones,
