Miyabi Jewelry Cord Series
Crafted with Toray Silook® Kumihimo

Silk-like beauty.
Engineered reliability for everyday jewelry.

A Japanese-made cord standard designed
for designers who require consistency, durability, and refinement.

Design Standard

Developed as a material standard for jewelry designers who need repeatable results across collections and production runs.

Silk-Like Refinement

Engineered triangular filaments create a soft, elegant luster without the instability of natural silk.

Everyday Reliability

Resistant to moisture, friction, and color change—designed for jewelry worn daily.

Why Cord Material Matters

In jewelry design, the cord is never just a supporting element.

It touches the skin, moves with the body, and directly affects both a piece’s appearance and longevity.

Natural silk is beautiful, but sensitive to moisture and friction.
Standard polyester is practical, yet often lacks refinement.

The Miyabi Jewelry Cord Series was developed as a third option—designed specifically for modern jewelry use.

What Is the Miyabi Jewelry Cord Series (Japanese Kumihimo Cord)?

The Miyabi Jewelry Cord Series is a line of Japanese kumihimo cords braided in Kyoto using Toray Silook® filament.

Rather than being simply a material choice, it functions as a defined standard developed for jewelry designers for jewelry designers who need repeatable results across collections and production runs.

Each cord in the series is designed to balance aesthetic refinement with practical reliability.

Material Choice: Toray Silook® (Silk-Like Japanese Filament)

Silook® is a high-performance Japanese filament developed by Toray Industries,
a leading Japanese materials manufacturer, to replicate the natural beauty of silk while offering superior stability.

Key characteristics include:

✨️ Refined, silk-like luster
💧 Resistance to moisture and daily handling
↔️ Excellent abrasion resistance
🎨 Highly stable color across production lots

These properties make Silook® particularly suitable
for jewelry intended for everyday wear and professional production.

Silook vs silk vs polyester filament cross section comparison

Why Silook Looks Refined

One defining feature of Silook® is its triangular filament cross-section.

This multi-faceted geometry softly scatters light,
creating depth and elegance without harsh reflections.

While natural silk has irregular triangular shapes,
Silook® offers uniformity—allowing refined appearance
to be maintained consistently across every strand.

Crafted in Kyoto

All Miyabi Jewelry Cord Series products
are braided in Kyoto using traditional Japanese kumihimo techniques.

Experienced artisans maintain precise tension throughout the braid,
ensuring stable roundness even at fine diameters.

Kyoto craftsmanship provides:

• Consistent production from fine to bold thicknesses
• Stable structure suitable for pendants and minimal designs
• Reliable quality for designers working with overseas workshops
• Strict inspection standards

This process ensures both beauty and reproducibility.

Braiding Structure for Jewelry

The Miyabi Jewelry Cord Series uses an eight-strand round braid
(Yatsu-gumi), the most widely adopted structure for jewelry.

This structure offers:

• Balanced roundness ideal for pendants
• Flexibility with sufficient strength
• High customizability through color placement

The same material can perform very differently depending on structure;
Yatsu-gumi provides a reliable foundation for professional jewelry design.

Not a trend-based cord — a material standard you can build collections on.
