Memories reside in objects.

The items we wear every day
accumulate countless memories
without us even realizing it.

On days we were happy, on days we worked hard,
and even on ordinary days that simply passed by,

that time is gradually etched into each item.

That is why, in addition to the beauty of design,
we value comfort that makes you naturally want to wear it forever
and quality.

Over time, its value deepens little by little.
We aspire to be a company that can deliver
such wonderful stories.

COIL is home to experienced jewelers and
jewelry designers.

Utilizing years of knowledge, experience, and masterful skills,
we create collections that prioritize comfort and sophisticated design.

Everything is produced and processed in Japan,
ensuring reliable quality.

More than just beauty, COIL is committed to materials and quality
because it's something you wear every day.

We use 92.5% pure sterling silver, which is free of nickel and cobalt.

It's a valuable precious metal used in jewelry worldwide.

Furthermore, we apply advanced processing technology used in the medical field,
and the surface is treated with a highly durable, high-quality titanium coating.

Achieving both durability and beautiful color,
we create a piece that can be cherished for a long time.

Rings are not merely worn; they are also a means of expressing your individuality and mood for the day.

At COIL, we offer a beautiful array of color variations,
proposing a ring that allows you to express your unique self,
while complementing your fashion and lifestyle.
