Small and medium-size jewelry makers in Yamanashi Prefecture are expanding their sales in other parts of Asia on the back of growing demand, with their techniques and designs hailed widely in China and elsewhere in the region.
The area's jewelry industry has prospered in part because of the polishing techniques developed among jewelry makers through local crystal production. Yamanashi now boasts the largest shipment share in the country by value.
During an international jewelry exhibition in Tokyo in January, potential buyers from foreign countries were drawn to the work of Crossfor Co., a jewelry maker in Kofu, Yamanashi Prefecture, whose designs use a special gem-setting mount that displays diamonds with an ever-glittering effect.
