Kaanch Aur Kanchan: Telling Glass From Gold
Launch library · evergreen read

काँच और कंचन में फ़र्क़ (kaanch aur kanchan mein farak) means the difference between glass and gold, a proverb about discernment, the ability to tell genuine worth apart from something that only looks valuable at first glance. The saying is used to praise someone's good judgement.
Or to caution against being fooled by appearances, a reminder that surface shine and true quality are not always the same thing at all. Learners can use this idiom in conversations about quality, honesty or careful judgement. Its clear, contrasting imagery, glass against gold, makes the underlying idea easy to remember and apply.
A useful related expression is asli aur nakli, real and fake, a more direct, everyday phrase covering similar ground without the proverb's poetic glass and gold imagery. Learning both gives a learner flexibility between plain, practical speech and more vivid, memorable expression. Elders sometimes offer this proverb as gentle advice to younger family members weighing an important decision, encouraging patience over a quick, dazzled first impression.
