For centuries, China has set the standard in Silk blending ancient tradition with modern expertise

When it comes to the finest silk in the world, China continues to hold a special place - both as the birthplace of silk and as a region with generations of expertise.

At By Dariia Day, while all our products are handmade in our hometown atelier in Poland, we source our signature mulberry silk from one trusted manufacturer in China - a family-owned company with a long-standing tradition of excellence in silk production. This partnership ensures that every piece we create meets the highest standards of luxury, sustainability, and care for your skin and hair.

 The origin of silk: China’s 5,000-year legacy

Silk has been deeply woven into the fabric of Chinese civilization for over five millennia. According to legend, silk was discovered around 2700 BCE by Empress Leizu, wife of the Yellow Emperor. While sipping tea in her garden, a silkworm cocoon is said to have fallen into her cup. As she unraveled the delicate thread, she discovered its remarkable strength and softness - and so began the story of silk.

Today, this legacy lives on through generations of artisans, combining ancient knowledge with modern innovation to produce the world’s most refined silks.

🌱 Why Chinese Silk Is the Best in the World

While silk is also produced in countries like India, Uzbekistan, and Vietnam, China remains the center of high-grade mulberry silk thanks to its rich tradition and refined techniques. Here’s why we continue to source from China:

• Unmatched quality: Silky-soft texture, high tensile strength, and an elegant natural sheen
  
  

• Expert craftsmanship: Families passing down sericulture skills through generations
  
  

• Sustainability: Many silk farms in China are small-scale and committed to eco-conscious practices
  
  

• Advanced precision: Modern technology ensures consistency and purity in every fiber
  
  

For centuries, the art of silk-making was one of China's most closely guarded secrets. Revealing the techniques -  from raising silkworms to reeling the threads — was once punishable by death. This exclusivity helped elevate silk to an elite luxury reserved for emperors and the nobility, and its reputation for beauty and refinement remains unmatched.

Silk fact: What is mulberry silk?

Mulberry silk, made from the cocoons of the Bombyx mori silkworm, is the gold standard in silk production. It’s softer, finer, and more durable than other types of silk - and it’s the only kind we use at By Dariia Day.

Our commitment to purity and tradition

At by Dariia Day, we believe luxury begins with intention. That's why we source only 100% pure mulberry silk from our trusted Chinese manufacturing partner - ensuring ethical practices, timeless craftsmanship, and exceptional quality.

Whether you’re slipping into a silk eye mask or resting your skin on a mulberry silk pillowcase, you can feel the story behind the silk - a legacy of care, beauty, and well-being, finished by hand in our Polish atelier.

All our silk is certified to meet the highest international standards, including GOTS (Global Organic Textile Standard) and STANDARD 100 by OEKO-TEX®, guaranteeing that every piece is free from harmful substances and produced with respect for both people and planet.
