Japanese aesthetics and K.UNO designs

The designs of K.UNO are rooted in respect for nature: strength, gentleness and beauty.
Japanese ukiyo-e, which played a significant role in the development of Art Nouveau, expresses the magnificence and beauty of nature as art and has great impacts on western countries. Such a high sense of aesthetics and exquisiteness and unique culture are rooted in Japan.

Designer and Custom-made

More than 50 designers pursue their crafts at K.UNO. They offer an enormous variety of designs to meet customers' requests. Consulting with customers diligently and drawing designs right in front of the customers, they produce more than 40,000 designs each year. K.UNO designs are drawn from each customer's unique concepts and thoughts and given shape by the designers.

One hundred and eighty craftspersons with expert craftsmanship

For over 35 years, K.UNO has produced a variety of custom-designed jewelry. Corresponding to the requests of Japanese customers with high standards, both appreciation for traditional techniques and innovative technologies come alive at the atelier.
To meet our customers’requests, all facets of jewelry making are conducted at our atelier in Japan by Japanese craftspersons with dexterous skills. Currently more than 180 craftspersons, the largest in number in Japan, strive to make special pieces for customers. Because we want our customers to wear our pieces of jewelry for a lifetime, most of our shops are attached to small ateliers and are able to offer repolishing, resizing and checking gemstones that are fee free and warranted for lifetime. Both the quality of high jewelry making and consideration for customers are qualities of K.UNO artisanship.


You can make your own rings with the attentive support of our experienced craftspersons. One of the courses takes two hours minimally, and customers can finish the ring and take it home the same day.
