Does it become wholesale jewelleries if I am buying handcrafted jewelleries in bulk?
Wholesale is business to business. Retail is business to end user. Nothing to do with bulk axcept wholesale is USUALLY bulk for obvious reasons. In your case you would buy from a wholesaler (in bulk) and sell retail (individual items) . A market stall would invariably be retail (not wholesale). A wholesaler would not generally sell individual items to the general public. There are people who advertise as wholesalers but aren’t really as they sell to the public.
