OUR STORY

The Allure of Large Diamonds

When I lived in North America, women walking down the street all wore large gemstones in their daily lives.

In contrast, my mother only wore her engagement ring for special dinners or ceremonies. And it was a tiny, tiny diamond.

There was also the historical context; wearing flashy rings was not considered "good," and modesty was seen as a virtue.

For a long time, the best-selling diamond size in Japan has been 0.3ct.

AURORA BY KOH Proposes

Precisely because lab-grown diamonds are affordable, why not choose a large one?

Living in an era of diversity, we don't need to be constrained by frameworks like "because of so-and-so."

You are free to enjoy jewelry without worrying about what others think.

The brilliance of a diamond is not just beautiful; it nourishes the soul.

Through AURORA BY KOH

Lab-grown diamonds are a new form of luxury brought about by scientific advancement.

While they may not have the romantic story of natural diamonds, "a miracle created by the Earth over hundreds of millions of years,"

the brilliance of lab-grown diamonds is "authentic" and "a crystal of sustainable beauty."

By offering lab-grown diamonds, which are still not widely known in Japan, at a more accessible price range through AURORA BY KOH, we hope to change consumer awareness, spread correct information, and anticipate future market changes.
