How to Tell if Your Vintage Saree Has Real Silver Zari or Tested Zari

18 October 2026

Many of us have a saree folded away that once belonged to a mother or grandmother. Its border still catches the light, but is that gold thread real silver zari, or the lighter "tested" zari that became common later? The answer matters, both for how you care for the saree and for what it is worth today.

Here is how to tell the difference at home, gently and without harming the saree.

What zari is made of

Zari is the metallic thread woven into the borders and pallus of silk sarees. It comes in three kinds:

Real zari is a fine silver wire, flattened and wound around a silk thread, then coated with a thin layer of gold. Most of its value comes from the silver. It was the standard in Kanchipuram, Banarasi and other fine silks for generations.
Tested zari replaces the silver with copper. The copper wire is coated with a little silver and then gold, so it looks almost the same when new. It became widespread because it costs far less.
Metallic zari has no precious metal at all. It is a coloured polyester film, cut into thin strips. It is light, very shiny and inexpensive.

A saree may have one kind in the border and another in the body, so check more than one spot.

1. Look at how it has aged

Time is the most honest test.

Real silver zari slowly darkens to a soft grey or black, the way silver jewellery does. Underneath, the thread still looks silvery.
Tested zari tends to turn reddish, brownish or even slightly green as the copper shows through the worn gold.
Metallic zari rarely tarnishes. It may stay bright for decades but look flat, plasticky or flaky up close.

2. Scratch a thread gently

Find a loose thread on the inside of the border or on the back of the pallu. Rub it gently with a fingernail or a pin.

If the colour underneath is silvery white, it is likely real zari.
If it is reddish or copper coloured, it is tested zari.
If the colour comes away like paint, or the thread is clear underneath, it is metallic.

3. Feel the weight and drape

Real zari makes a saree noticeably heavier, especially in a wide border. The zari feels soft and supple and drapes with the silk. Tested zari is a little stiffer. Metallic zari is very light and can feel scratchy against the skin.

4. The burn test, with care

If you can spare one short thread from a hidden place, a careful burn test is very telling. Do it over a sink or a steel plate, away from the saree, with water nearby.

Real or tested zari: the silk core burns away with a smell like burnt hair, leaving a fine metal thread or ash behind. It does not melt.
Metallic zari: it shrivels and melts into a hard little bead and smells like burning plastic.

The burn test tells you whether there is metal. It does not tell silver from copper, so combine it with the scratch test.

5. Check the paperwork and marks

A Silk Mark label, a Handloom mark or the original bill from a well-known weaver or shop are good signs. Older bills sometimes mention "pure zari" or the weight of zari used. A Kanchipuram saree with a Geographical Indication tag was made to traditional standards too.

What these tests cannot tell you

Home checks give you a strong hint, not a certainty. Workmanship, wear and repairs can all confuse them. The only way to know exactly how much silver is in a saree is to test it properly, with an assay or an XRF scan.

That is what we do at SellYourZari. Once your saree reaches us, we fully verify the zari before confirming what we can pay. If your saree turns out to be tested or metallic zari, we will tell you honestly.

Before you sell

Do not cut or unpick the zari yourself. Whole sarees are easier to verify, and you might damage a border you would rather keep.
Keep any bills, tags or family notes about where the saree came from.
Take a few clear photos of the border and pallu in daylight. They help us give you a better first estimate on WhatsApp.
