Real tussar silk shows irregular slubs, small thickenings scattered through the weave at no fixed interval. Hold the fabric to a window and the light should come through unevenly. Genuine tussar also feels dry and cool rather than slippery, keeps a matte gold undertone under whatever colour it has been dyed, and a single thread burns to a black crisp that smells of burnt hair.
A polyester imitation fails all four. It shines evenly, feels faintly waxy, warms fast against your palm, and melts into a hard bead when burnt. Those checks identify real tussar silk faster than anything printed on the packet.
Six checks, in the order I would use them
- Hold it up to light. Real tussar transmits light patchily because the yarn thickness varies along its length. An imitation glows flat and even.
- Look for a rhythm in the slubs. This catches most fakes. Genuine slubs fall randomly. Woven and printed imitations repeat their texture every few centimetres, because a machine put it there.
- Touch the back of your hand to it. Tussar is cool at first contact and warms slowly. Polyester feels slightly warm from the first second, and slightly greasy.
- Crush a corner in your fist for five seconds. Tussar creases sharply and holds the crease. Polyester springs back almost clean. A saree sold as tussar that refuses to crumple is worth questioning.
- Check the reverse side. On real tussar the slubs read from both faces, because they sit in the yarn itself. On a printed imitation the texture lives only on the front.
- Burn one thread. Pull a single thread from an inside edge, never from the body. Silk is a protein fibre, so it burns slowly, self-extinguishes, smells of burnt hair, and leaves black ash that crushes to powder. Polyester melts, smells chemical, and leaves a hard bead.
The first five take under a minute on a shop floor. The sixth is for when the saree is already yours and you want certainty.
How to identify real tussar silk by touch alone
If you can only do one thing, run a fingernail slowly across the grain. You are feeling for interruptions. Real tussar catches, releases, catches again, at no predictable spacing. The surface is dry, closer to fine raw linen than to a satin.
Mulberry silk is the opposite: continuous, smooth, cold, slippery. If a shopkeeper hands you something that slides like water and calls it tussar, it is either mulberry or a synthetic pretending to be mulberry. Neither one is tussar. Our tussar and mulberry comparison sets the two side by side if you want the longer version.
Why real tussar has slubs at all
The slubs are not a flaw anyone is tolerating. They are unavoidable, and that is exactly what makes them useful to you.
Tussar comes from Antheraea moths that live outdoors on Arjun, Asan and Sal trees rather than being fed indoors. The filament in a wild cocoon is shorter and coarser than a mulberry filament, and it will not unwind as one clean continuous thread. Reelers join shorter lengths together, and every join leaves a small thickening. No joins means no tussar.
The same forest diet is why undyed tussar arrives in honey, wheat and dull gold shades before any dye is used. A pale tussar with a cold blue-white base has usually been bleached hard, which weakens the fibre. There is more on the fibre itself in what is tussar silk.
What the price tells you
Across the Indian market, tussar sarees run from roughly ₹1,500 for a light printed piece to ₹25,000 and beyond for heavy work.
Below about ₹1,000, the word tussar on a label almost always means polyester. Between ₹1,000 and ₹1,500 you are usually looking at a tussar blend, where a small percentage of real tussar sits in a viscose or polyester ground and the label still says tussar in large letters. Ask for the composition in writing. A seller who cannot give you a fibre percentage is telling you something.
Watch the wording too. Tussar finish, tussar look, art tussar and semi tussar are all legal ways to sell you something that is not tussar.
Where the imitations turn up
Marketplace listings are the worst offenders, because the photograph is often of a real tussar and the piece shipped is not. Buy where the composition is stated on the product page rather than in a caption.
Shops in tourist markets carry the second-highest risk. Silk Mark tags help, but only when the tag is attached with an intact holographic seal, since loose tags get moved between pieces.
What we sell, stated plainly
Our tussar sarees are genuine tussar silk. The Madhubani-inspired art on them is printed, and we say so on every product page, because a printed piece and a painted one are separated by thousands of rupees and nobody should learn that after paying.
Tussar silk sarees at Koshnika are priced ₹1,860 to ₹1,960, blouse piece included. Each is 5.5 metres of saree plus a 0.8 metre unstitched blouse piece. Free shipping across India, cash on delivery, and 48-hour returns.
Two to look at
If you want to see the natural base colour with nothing hiding it, Natural & Grey Tussar Silk Saree leaves the body undyed and sets a grey border against it, which is the clearest way to read both the slubs and the gold undertone. ₹1,860, blouse piece included.
For something with more going on, Katha – Ivory Tussar Silk Saree carries a narrative Madhubani-inspired print across an ivory ground, and the texture still shows through the print, which is a fair test of how the fabric behaves. ₹1,860, blouse piece included.
Whatever you buy, store it in muslin rather than plastic and refold along new lines every few months. Tussar splits along old creases, which is covered properly in how to store sarees.
