The World's First 18K Purple Gold Dial Watch Launched

TOKYO (Perla) -- Jewelry Miura Co., Ltd., a Japanese jewelry manufacturer known for its innovative materials and craftsmanship, has launched the world's first mechanical watch featuring a dial made from 18K purple gold on Kickstarter.

Purple gold is an exceptionally rare and beautiful 18K gold alloy created by combining pure gold with aluminum. Unlike plated or coated materials, its distinctive purple color is derived from its unique crystal structure, giving it a permanent and naturally rich tone. However, due to the significant difference in density between gold and aluminum, special techniques are required to properly fuse the two metals.

In addition, the material's crystalline structure makes it inherently brittle, meaning it cannot be processed using conventional techniques such as bending or stretching. As a result, only highly skilled artisans using advanced methods are able to work with this material, making the global production of purple gold extremely limited. Within the world of high-end jewelry, it is regarded as a truly distinctive and prestigious material.

Jewelry Miura has secured patents for its purple gold production technology in Japan, the United States, and Europe. In addition, its 18K purple gold has been officially hallmarked by the Japan Mint, further demonstrating its authenticity and material quality.
