How can I identify a real Zari in a Kanjivaram saree?

Real Zari in Kanjivaram sarees is typically made from genuine gold or silver threads, which give the fabric its luxurious appearance. You can gently rub the threads between your fingers; if they are rough or break easily, they may be fake. A definitive test is to scratch the Zari lightly; if white threads appear underneath, it indicates a fake, whereas crimson-colored threads signify a real Zari.
