[HIGHLIGHTS] The secret ingredient of your luxury perfumes is whale vomit - half a kilo of it is worth 10 thousand dollars - voila! Fashion

Gray amber is excreted from the digestive system of sperm whales. Gray amber is a fragrant, solid, wax-like substance that smells like feces in its creation but later, after long exposure to the sun, acquires a sweet and earthy smell.

An odorless alcoholic substance called ambergris can be produced that helps the fragrances of perfumes last longer. Due to the scarcity of whale vomit, one gram is worth around $27 - half a kilo can be worth more than $10,000.
