From Hakai magazine: This is ambergris, one of the world’s unlikeliest commodities. The waxy substance formed in the gut of around one in 100 sperm whales is frequently described as vomit, but is almost certainly expelled from the other end of the animal… Despite its origins, ambergris, with its unique scent, fixative properties, and perceived ability to elevate other olfactory notes, has been prized by the perfume industry for hundreds of years. It has also been consumed as a delicacy and administered as medicine. At times, it has fetched prices more than twice that of gold. Today, it still changes hands for up to US $25 per gram
