"Is this a pure Kanjivaram or a soft silk?" It is the single most important question a saree buyer can ask — and the one imitation sellers hope you never will. The difference decides whether you are paying heirloom prices for heirloom silk, or heirloom prices for polyester.

This guide teaches you to tell pure silk from soft silk from an outright fake, using the same checks our own quality team runs before a saree earns the Aikyatha label.

First, clear up the confusion: pure silk vs soft silk

These are not opposites, and "soft silk" is not a downgrade. Both can be genuine.

• Pure (traditional) Kanjivaram: heavy three-ply mulberry silk with substantial zari. Stiff, grand, built to last generations.
• Soft silk Kanjivaram: the same pure silk, woven lighter with finer zari for a fluid drape and everyday comfort. Still 100% silk — just a different weave.
• Imitation / art silk: polyester or rayon made to look like silk, with plastic-coated imitation zari. This is what you must learn to catch.

So the real question is not "pure or soft" — both are fine choices — but "genuine silk or fake?" Here is how to know.

The checks you can do yourself

1. The burn test (a single thread)

Pull a stray thread from the fringe and, safely, burn it. Real silk burns slowly, smells like burnt hair, and leaves a soft black ash you can crush to powder. Polyester melts, smells chemical, and leaves a hard plastic bead. This is the most reliable at-home test.

2. The feel and the warmth

Rub the saree briskly between your palms. Pure silk generates warmth and a faint friction. Polyester stays cool and slippery. Genuine silk also has an uneven, organic sheen that shifts colour as you turn it; fakes glare with a flat, uniform shine.

3. The weight and the body

Even a soft silk has a certain body and fall. If a "pure Kanjivaram" feels featherweight and papery for its claimed price, be sceptical.

4. The zari scratch

Gently scratch the zari thread. Genuine zari reveals a red or reddish-silver silk core under the gold. Imitation zari shows white plastic or thread underneath.

The proof that settles it: Silk Mark

The at-home tests build confidence, but the definitive proof is the Silk Mark — a holographic tag issued by the Silk Mark Organisation of India that certifies 100% natural silk. A genuine seller attaches it and shows it without being asked. Pair it with the Handloom Mark for handwoven assurance, and a clear invoice naming the silk and zari type. Together, these three are your real protection. Our connoisseur's walkthrough on authenticating a genuine Kanchipuram shows exactly what to look for.

Signs you may be looking at a fake

• Price that seems too good for "pure silk" — genuine mulberry silk and real zari have a floor.
• No Silk Mark tag, and vague answers when you ask about the zari.
• A flat, plasticky uniform shine and a cool, slippery hand.
• Imitation zari that is bright yellow-gold with no red silk core.

None of this means soft silk or tested zari is "bad" — affordable, genuine silks are wonderful. It only means you deserve to know what you are buying. The features that separate the real thing are covered in our piece on what authentic Kanchipuram manufacturers offer.

Which should you choose — pure or soft?

Match the saree to the moment:

• Pure traditional Kanjivaram — for your wedding, heirloom-worthy occasions, and gifting across generations.
• Soft silk Kanjivaram — for receptions, festivals and repeated wear where comfort and drape matter, as we explain in our note on soft-silk pattu sarees.

Frequently asked questions

Is soft silk less valuable than pure silk?

Not necessarily — it is still 100% silk, simply woven lighter. It can carry genuine zari and real craftsmanship; it is a different style, not a lower grade.

Can I do the burn test in a shop?

A reputable seller will let you test a fringe thread. If a seller refuses even that, treat it as a warning sign.

Does the Silk Mark guarantee it is a Kanjivaram specifically?

The Silk Mark guarantees pure natural silk. For Kanjivaram specifically, combine it with the Handloom Mark, the weave characteristics above, and a trusted seller's invoice.
