Kyocera Corporation (President: Tetsuo Kuba) today announced that the company’s recrystallized ruby — also known as ‘created ruby’ — has been employed for the first time in a decorative design application as watch parts. Previously the company’s original crystal technology, which produces synthetic gemstones with crystalline structures identical to naturally occurring gemstones, was only used for traditional jewelry applications.

The ruby material has been utilized in the design of the limited-edition model MR-G, the highest-end series in Casio Computer Co., Ltd.’s shock-resistant G-Shock brand watches. 4.85 carats (approx. 0.97g) of Kyocera’s recrystallized ruby has been set into the inner-casing around the numerals in the city code display* design. The recrystallized ruby rough stone is precisely cut into a ring shape of roughly 3cm in diameter — a size and shape that otherwise could only be made possible with natural ruby if the highest quality stone was used. Furthermore, the pure ruby-red coloration only attainable in a recrystallized ruby is the perfect embodiment of the MR-G's theme color, Japanese traditional deep red, and boldly expresses the strength and beauty of the watch.

“Conventionally, our recrystallized gemstones have primarily been used for jewelry applications, but starting from last autumn, we have been developing them to be used in a wider range of decorative applications,” stated Takafumi Matsuda, Executive Officer & General Manager of the Kyocera Corporation Jewelry & Application Products Division. “Kyocera will utilize the know-how accumulated in the 35-years of experience since the creation of our recrystallized gemstones to expand the business beyond jewelry and build a pillar for business in diverse decorative material applications.”

The limited-edition watch which utilizes Kyocera’s recrystallized ruby will be featured at Casio’s booth in one of the world’s largest international watch and jewelry shows, BASELWORLD 2010 (Palace 4), taking place in Basel, Switzerland from March 18-25.

About Recrystallized Gemstones

Kyocera’s recrystallized gemstones — including the representative emerald, ruby and sapphire — are born from the company’s crystal technology and possess the same composition and structure as naturally occurring gemstones. Recrystallized gemstones, which can be produced with fewer internal flaws and impurities than naturally occurring gemstones, feature several advantages including: Brilliant coloration, high transparency, durability for easy cutting, and a wide range of size and shape possibilities.
