Diamond manufacturing — Business MegaBrands 2026–27

Diamond manufacturing companies cut and polish rough diamonds into finished stones, and increasingly grow and process laboratory-grown diamonds, mostly in Surat and Mumbai. They sell to jewellery makers and traders worldwide. Because much of the world's diamond polishing takes place in India, the category supports skilled employment in Gujarat and contributes substantially to the country's gem and jewellery exports.
