When it comes to silk, identifying authentic, high-quality silk is key to ensuring you enjoy its incredible benefits. From promoting healthier skin and hair to improving your sleep quality, real silk is a worthwhile investment - but only if it’s the genuine article.
As our customers know, the benefits of silk pillowcases and accessories are extensive, however, with so many synthetic alternatives like polyester and satin blends on the market, it can be challenging to determine if the silk you’re purchasing is genuine.
In this guide, we’ll share simple and effective ways to identify real silk, answer the most commonly asked questions about authenticity of silk, and provide expert tips to help you confidently choose only the finest silk.
Is Mulberry Silk Real Silk?
Yes, mulberry silk is not just real silk, it's the highest quality silk in the world. The confusion usually comes from the name. "Mulberry" refers to the source, not the material. Mulberry silk is produced by Bombyx mori silkworms that feed exclusively on mulberry leaves. This controlled, specialist diet is what gives mulberry silk its exceptionally smooth, consistent, and fine fibre; qualities you simply cannot replicate with synthetic alternatives.
So when you see "100% mulberry silk" on a label, it means you're getting the purest and most premium form of real silk available.
What to look for on the label
Genuine mulberry silk products should state "100% mulberry silk" (not "silk blend," not "silky feel," not "satin"). The label matters because many products use the word silk loosely to describe the look or feel of a fabric rather than its actual composition.
At The Silk Collection, every product is made from 100% pure mulberry silk at 22 momme weight, the optimal thickness for pillowcases and hair accessories. Our entire collection is OEKO-TEX 100 certified, meaning it's been independently tested and verified to be free from harmful chemicals. You can find the material composition listed on every product page and on the label of every product we sell.
The bottom line: if something is labelled mulberry silk and comes from a reputable seller with certifications to back it up, it is real silk, and the best kind at that.
Why Identifying Real Silk Matters
We often here common misconceptions about silk, such as 'all shiny fabrics must be silk' and 'synthetic silk is just as good', however this certainly isn't the case.
Real silk is a premium fabric made from the natural fibres. Unlike synthetic alternatives, genuine silk provides unparalleled benefits, including:
- Gentle, frictionless care for skin and hair.
- Moisture retention to keep skin hydrated
- Hypoallergenic properties, ideal for sensitive skin or allergies.
- Natural temperature regulation for year-round comfort.
Alternative non-silk materials not only lacks these benefits but often fails to deliver the luxurious experience you expect. This is why using a satin vs. silk pillowcase can end up feeling uncomfortable overnight, as it doesn't help to naturally regulate temperature like real silk does.
Spotting the difference between real vs. fake silk ensures you get the most out of your investment and enjoy all of the benefits.

The Best Ways to Spot Real Silk vs. Fake Silk
Here are five simple and reliable methods to determine if your silk is genuine:
1. The Touch Test
- How it works: Real silk feels incredibly soft, smooth, and luxurious to the touch. It glides under your fingers without any resistance.
- What to look for: Rub the fabric gently between your fingers. Real silk warms up quickly due to its natural, protein-based composition, whereas synthetic silk remains cool and may feel plasticky or slippery.
💡 Expert Tip: Test how the silk feels against your face - real silk is soothing and naturally cool. This is why using a real silk pillowcase is the ultimate choice for a comfortable night's sleep.
2. The Burn Test
- How it works: Burn a small thread from the silk. Genuine silk burns slowly, smells like burnt hair, and leaves a brittle ash.
- What to look for: Synthetic silk melts instead of burning, emitting a chemical or plastic smell.
💡 Expert Tip:This is the best way to test real silk threads, although not always the most practical as you don't want to burn your brand new silk pillowcase! If you do have a loose thread or sample material, this is the most effective and clear method to confirm if the silk is genuine silk due to the obvious differences.
⚠️ Safety Note: This test should only be performed on a small, inconspicuous thread. Handle fire with care and avoid damaging your fabric unnecessarily.
3. The Price Test
- How it works: Compare the price of the silk item to similar products on the market.
- What to look for: Genuine silk is a luxury product, so it’s unlikely to be sold at a very low price. If a deal seems too good to be true, it probably is.
💡 Pro Tip: Look for silk items priced appropriately for their momme weight and quality. We only use 22 momme, 100% mulberry silk to craft our silk pieces. This means that our premium silk products do come at a higher price, due to the quality of the silk we use. Find out more about the importance of momme count here.
4. The Shine Test
- How it works: Hold the silk under a light source and observe how it shines.
- What to look for: Real silk has a soft, natural shimmer that changes with the angle of light, giving it a unique depth and richness. Synthetic silk often appears overly shiny with a uniform reflection.
5. The Water Test
-
How it works: Real silk absorbs water easily, whereas fake silk tends to repel it.
-
What to look for: Place a drop of water on the fabric—if it absorbs quickly without leaving a visible stain, it’s likely genuine silk.
This method is non-invasive and ideal for testing silk garments or home décor items.
Our Top Tips to Ensure You’re Buying Real Silk
