About BYZANTIUM

Founded in 1992

Taking its name from the splendid Byzantine Empire of Western history, Byzantium Precious established a new approach to jewelry design, distinct from conventional practice. From the thoughtfully conceived retail space to each distinctly designed piece, we have remained committed to integrating expertise, aesthetic refinement, and creative vision into our work—becoming a defining jewelry design house in Tainan. Over three decades, Byzantium Precious has devoted itself to diamonds, colored gemstones, and precious metal jewelry. We offer comprehensive knowledge of diamond grading and colored gemstone appreciation, carefully selecting high-quality stones and metals that achieve excellence in color, clarity, and cut, revealing the precision of our craft and the extraordinary character of each piece.

Precision cutting

Beyond design and fabrication, we invest in the research and refinement of specialized gemstone cutting techniques. By precisely calculating the refractive properties inherent to each stone, we determine the optimal cutting angles with exactitude. Combined with our distinctive cutting designs and hand-finishing methods, this approach reveals the subtle and compelling luminosity distinctive to each gemstone. We believe every stone possesses its own character, and the convergence of optical science with refined craftsmanship allows that character to emerge complete.

BYZANTIUM: a new chapter

In 2026, Byzantium Precious relocated to Tainan's East District and welcomed its second generation of leadership. Together, we embark anew under the reimagined brand identity BYZANTIUM Precious Metal & Gemstone. We will honor three decades of expertise and dedication while embracing innovative design and refined craftsmanship, continuing to offer each client jewelry that balances quality, aesthetic beauty, and emotional resonance.
