You've seen "Grade 6A Mulberry silk" on luxury bedding labels — but what does it actually mean, and is it worth the premium? Here's the simple, honest breakdown.
What is Mulberry silk?
Mulberry silk is the highest-quality silk in the world.
It's produced by silkworms (Bombyx mori) fed an exclusive diet of mulberry tree leaves. This controlled diet creates silk fibers that are remarkably pure, uniform, and long — exactly what gives Mulberry silk its signature smoothness, strength, and shine. You'll find it in our purest pieces, like the Lunaire Mulberry Silk Duvet Cover.
What does "Grade 6A" mean?
Silk is graded by quality — by the length, uniformity, and purity of the threads. The scale runs from the lowest up to the highest: 6A.
When bedding is made from Grade 6A Mulberry silk, you're getting the top tier of the top material — nothing higher exists.
Why Grade 6A Mulberry silk is worth it
- Temperature regulating — naturally cool in summer, warm in winter.
- Hypoallergenic — naturally resistant to dust mites, mold, and allergens.
- Gentle on skin & hair — reduces friction that causes frizz, breakage, and sleep creases.
- Long-lasting — long fibers make it more durable than lower grades when cared for properly.
