Ambergris

Physical Properties

Hardness: 0.5-1.0 (soft/waxy); Color: Dull grey, tan, or yellowish-brown; Luster: Waxy to earthy; Crystal Structure: Amorphous (non-crystalline); Specific Gravity: 0.780 to 0.926 (floats in water); Cleavage: None.

Formation & Geological History

Produced in the digestive system of sperm whales to protect the intestine from sharp squid beaks. It ages for years floating in the ocean, oxidizing through exposure to sun and salt water.

Uses & Applications

A high-end fixative in luxury perfumes to make scents last longer on the skin; highly valued by fragrance houses and collectors.

Geological Facts

Historically called 'floating gold'. Fresh ambergris has a fecal odor, but as it ages it develops a sweet, earthy, or musky scent. It is one of the most valuable natural substances found on beaches.

Field Identification & Locations

Identify by its waxy texture, ability to float in water, and the 'hot wire test' (it should melt into a dark, glossy, fragrant liquid when touched with a hot needle). Found on coastlines worldwide, particularly after storms.
