Yeah it's actually a great idea. most of these stones are raw and unpolished, India is the largest importer of Gems and precious stones in the World. Mostly because of the huge jewellery industry in india women here wear jewelleries for every other occasions be it religious or anything, also there are many festival where we buy jewelleries because of traditions and religious customs and we also export a lot of finished jewellery and stones like polished diamonds, etc.
