📜 Origin & History

Ruby red originates from the color of rubies. Rubies were anciently called 'La Zi' or 'Hong La', imported from the Western Regions and Burma during the Han Dynasty, counted among the Seven Treasures of Buddhism. The red of rubies has a crystalline translucence, completely different from ordinary reds.

Tang Dynasty nobles were proud to inlay rubies. The treasure caskets unearthed from the Famen Temple are inlaid with rubies and turquoise, a brilliant and dazzling contrast of red and green.

During the Ming Dynasty, Zheng He's voyages brought back large quantities of Southeast Asian gems, and rubies became the protagonists of court jewelry. The gold crown of the Wanli Emperor, unearthed from the Dingling Mausoleum, is set with a huge ruby.

In the Qing Dynasty, 'Lang Kiln Red' porcelain successfully fired a ruby red glaze color. Supervised by Lang Tingji, this 'Lang Kiln Red' used copper as a colorant, reduced at 1300°C to produce a color as crystal clear as a ruby.

Modern ruby red remains the top color in the jewelry world. The per-carat price of 'pigeon's blood' rubies exceeds that of diamonds, making them absolute stars at auction.
