Gary and Angela Williams of Overton, Lancashire, were walking along Middleton Sands beach near Morecambe Bay when they noticed an unusually large rock. Others had probably passed by the object before, but no one thought it was noteworthy. Fortunately, the Williams decided to inspect it, which proved to be the best decision they’ve ever made…

Looking at the “rock,” and judging by its distinct smell, which reminded them of rotting fish, the couple knew they had struck gold. What they discovered was ambergris, also known as “whale vomit,” a valuable ingredient in the perfume industry.

They knew it was their lucky day after reading about the value these “rocks” can reach. What exactly is ambergris? “When sperm whales swallow sharp objects – such as the horny beaks of squid, which are their usual food – their intestines secrete a sticky substance that envelops these sharp debris so as not to injure the intestinal mucosa.

These residues agglomerate over time, forming lumps of varying sizes that are removed either with feces or regurgitated. Under the influence of the sun and seawater, this mixture hardens and develops a distinct aromatic odor.”

Gary also stated that if it sells for a good price, they will be one step closer to realizing their dream of owning a static caravan. Garry and Angela’s discovery, weighing 1.5 kg, is estimated to be worth $70,000 USD.
