Passing on Technology

TASAKI manufactures products based on the three guiding principles of Quality, Creativity and Craftsmanship.

Our uncompromising insistence on quality is reflected in the meticulous care with which we farm our pearls amid the challenging conditions of nature and in our diamond polishing, which achieves a 100% yield of 3EX (triple excellent cut grade) diamonds. The timeless, innovative designs created by our globally active designers are brought to life through the highest standards of artisanal craftsmanship.

As an organization, we have developed schemes to pass that commitment to quality and craftsmanship traditions on to the next generation, including systematic on-the-job training and the active recruitment of young people with high potential.

Carrying on the Pearl Farming Industry

One of the challenges for the maintenance and growth of the pearl farming industry is the development of the younger generation. TASAKI actively recruits young people with high potential to work at our pearl farms in the hope that they will carry the industry forward into the next generation. Pearls are living resources and assets, and there is a great deal of knowledge and skill to be acquired through practical experience. For this reason, we nurture our young people with schemes that enable them to learn with care and precision about each process, from spat production to growing juvenile oysters and from implanting the nucleus to harvesting the pearls.

Intricate, Delicate Work of Polishing Diamonds

In the early 1990s, when it had been thought impossible to achieve a grade of diamond cut better than “Very Good,” TASAKI succeeded in realizing the grade above “Excellent,” and we have since become a leader in this industry.

Day after day, our craftsmen work hard to master the full process of round brilliant cutting and to achieve their goal of a 100% yield of “3EX”. The grade of “3EX” is “Excellent” in all three criteria of proportion (overall evaluation of the cut), polish (the quality of the diamond’s surface finish), and symmetry. They set their own individual areas for improvement and receive monthly feedback on their commitment in order to further standardize quality.

Jewellery Creation Unconstrained by Conventional Thinking

TASAKI’s innovative jewellery is created by our uncompromising craftsmen, with their seasoned experience and deep knowledge.

The highly original creations of our globally active designers can only be realized by our first-class craftsmen, whose skills are constantly evolving. Those craftsmen are also working to pass those skills onto the next generation by using their deep knowledge and abundant experience to provide practical training for young people with high potential.
