KYOCERA Introduces Irish Claddagh Ring Designed by Paul Costelloe, Using Hypoallergenic COBARION

Using new material COBARION, symbolic Irish design meets Japanese technology; portion of proceeds to benefit Great East Japan Earthquake recovery

  • Corporate

Kyoto/London – Kyocera Corporation (President: Hideo Tanimoto) today announced that it has developed a hypoallergenic Claddagh ring with renowned Irish-born designer Paul Costelloe. The jewelry utilizes COBARION, a new material that rivals platinum in shine but which is much less likely to cause metal allergies*1. The product is now available to the Japanese market and overseas sales are under consideration.

Dating back to the 17th century in Ireland, the traditional Claddagh ring is given to represent love, loyalty and friendship. The ring is now available in two types: the stylish thin AMATERUS and the gorgeous bold WADADUMI. Both styles are unisex, making them ideal for matching rings for friends or romantic relationships. A part of the sales of this product will be donated to the recovery support of the Great East Japan Earthquake.

“The COBARION Claddagh is a symbol of the deep and long friendship between Ireland and Japan — the joining of hands of Irish design and Japanese technology. It is also a sign of the deep respect I have for the city of Kamaishi ― where COBARION is developed ― Iwate Prefecture and the Tohoku Region, and a remembrance to all that was lost in the Tohoku Earthquake of March 2011,” said Paul Costelloe. “I am very excited to be working closely with Kyocera to make the COBARION Claddagh a success for Kamaishi, for Japan, and for the world.”


COBARION material is a type of Co-based alloy jointly developed by Tohoku University, Iwate Prefecture, and Eiwa Co, LTD (Kamaishi City, Iwate Prefecture). A collaboration of industry and university, the team developed the new biologically friendly material by minimizing the nickel content, typically a main cause of allergy, while maintaining a brightness and sparkle that is equal to platinum. In addition, it features four times higher toughness than silver so a COBARION ring is virtually scratch-proof and will not easily discolor.

About the Claddagh Ring

The Claddagh ring is a traditional design that has been produced in Ireland for a few hundred years and loved by many around the world. It features two hands clasping a heart surmounted by a crown to depict love (the heart), friendship (the hands), and loyalty (the crown). Depending on which hand the ring is worn and the direction of the heart, the ring can be worn to indicate a person’s relationship status: single, in a relationship, engaged or married.
