Pure Zari vs Tested Zari: How to Tell the Difference in a Banarasi Saree

What is zari?

Zari is the metallic thread woven into Banarasi sarees, dupattas, and suits to create their signature borders, motifs, and jaal (net-like) patterns. It has been used in Indian textile weaving for centuries and is what gives Banarasi silk its characteristic shimmer.

What is the difference between pure zari and tested zari?

Pure zari is made by wrapping a fine silver wire (traditionally coated in gold) around a silk thread core. It is more expensive, has a slightly duller, warmer metallic sheen, and does not tarnish quickly. Tested zari uses a polyester or synthetic thread coated with a metallic finish, is significantly more affordable, has a brighter, shinier finish, and can tarnish or dull faster over time.

Is tested zari a lower-quality or fake product?

Not necessarily — tested zari is not counterfeit, it's simply a different, more budget-friendly material, and many buyers choose it deliberately for everyday or lighter festive wear. The important thing is that a seller discloses clearly which type of zari is used, rather than implying tested zari is pure.

Does pure zari need special care?

Yes. Sarees with pure zari should always be dry-cleaned, stored away from moisture and direct sunlight, and folded along soft lines to prevent the metal thread from cracking. Tested zari is generally more tolerant of handling but can tarnish with excess humidity.

Every product on Shades of Banaras clearly specifies whether pure or tested zari is used in its specification table — browse our Banarasi silk saree collection.
