About Us


R ETHICAL jewelry is made into high-quality jewelry that preserves the beauty of ethical materials from around the world and shows respect for craftsmanship.

We carefully deliver ethical 18K gold and conflict-free diamonds as design work while adhering to our unique "Five Promises."

Ultimate simplicity, solid appearance, and classical essence.

Because it is something we will share with each other for a lifetime, we are looking for something that has intrinsic value and creates a sustainable cycle.

Harmony with the Earth Beauty is cyclical

Clouds grow, rain falls, the soil gets wet, flowers bloom, and fruits grow. The lives of insects, birds, and animals circulate. Humans are also part of the life of the earth. Minerals existing on the earth do not increase or decrease. Connected with the natural world, and with its life, it will eventually travel through the ages.
