Amber seed, also known as ambergris or grey amber, is a rare and valuable substance produced by the sperm whale. It is formed in the whale’s digestive system as a result of an irritation caused by the beaks of squid or other sharp objects. Over time, the whale’s digestive enzymes transform this irritation into a solid waxy substance. Amber seed has a unique and complex aroma, often described as musky, earthy, and sweet. It is widely used in the perfume industry as a fixative to enhance the longevity and diffusion of fragrances. Due to its scarcity and high demand, amber seed is considered a luxury ingredient. Its use dates back centuries, and it continues to be highly prized today.
