The supernatural hard-boiled duck is not the first picture to come to mind when we think of perfumes, otherwise we will be a symbol of magic and attractiveness. But the main ingredient that makes the sophisticated aroma that is still on the skin is exactly this digestive gastrointestinal amber.

Despite being one of the most expensive materials in the world (its value approaching gold has sometimes tripled), the amber is one of the least known substances in the world. But with this unusual and very tempting book, Christopher Kemp promises to change that by revealing the unique history of Amber Amber.

The rare secretion produced only by amber whales, which have a fondness for squid, but the inability to digest their beaks, expels amber in the sea and floats on ocean currents for years, slowly turning, before being washed on the beach like a rare waxy pebble. They could appear almost anywhere but were found so they rarely appear anywhere.

Kemp's journey begins with an interview on New Zealand's beach with a giant mass of fake amber - determined after a lot of excitement simply to be lard - which inspires the overall quest for amber and his story. It takes us from the rocky New Zealand coastline to Stuart Island, a remote wind island in the South Seas, to Boston and Cape Cod, and back again.

Along the way, it follows collectors and dealers who inhabit secret amber trade in modern times. "Floating Gold" is a fun and lively history that not only covers these precious gray blocks and those looking for them, but also provides an informative account of the natural history of whales, squid, ocean ecology and even the history of perfume industry.

The obsession of Kemp the maniac is contagious, and eager readers will feel that they have stumbled upon the precious virtue of this interesting article.
