It is conceivable that Ambergris is the result of a pathological condition caused by irritation of the whale’s stomach due to certain indigestible particles in the whale’s food. It is one of the few natural perfumery raw material which cannot be cultivated. It is a pale grayish or creamy yellow to brown or dark brown waxy solid mass. On ageing, the material lightens in colour, particularly when exposed to daylight and salt water. Consequently, you have different grades of ambergris.
