Kyocera’s jewelry business celebrates its 50th anniversary this year. To commemorate the milestone, the business, which applies crystal technology cultivated through fine ceramic manufacturing, is strengthening sales through participation in jewelry exhibitions and enhancing its e-commerce operations. It aims to increase business sales by 30% compared to fiscal year 2024 within three years. A briefing was held on the 21st at the Kyoto Fushimi Business Office (Fushimi Ward, Kyoto City), where the business is based.
The company began developing gemstones by applying its crystal technology and succeeded in manufacturing emeralds in 1975. The business was driven by the philosophy of founder Kazuo Inamori, who believed that “creating beauty that is difficult to find in nature” was a meaningful endeavor for a manufacturer.
Currently, the focus is on lab-grown gemstones such as diamonds and sapphires. The market for these gems is expanding, particularly in North America, where awareness is high. Kyocera leverages its proprietary crystal growth technology to produce high-quality, large, and beautiful synthetic gemstones.
The company plans to further expand its jewelry business by strengthening its brand and sales channels. The goal is to achieve the aforementioned 30% sales growth by leveraging the anniversary momentum and the growing demand for sustainable and ethically sourced gemstones.
