Ambergris is a natural secretion from the giant sperm whale, created from indigestible materials and gastric juices. After being ejected and floating in the sea for years, it transforms into a unique substance with complex scents of seaweed, salt, dry wood, sweet nuances, and earthy, incense-like tones. Today, ambergris can be used in its natural form, not just synthetically. Historically, it was highly valued in the Middle East, India, and China for its supposed aphrodisiac and medicinal properties and was even used by the European elite in the 1600s. Casanova reportedly used it to enhance his allure. Its rarity and high demand make ambergris one of the most prized materials in perfumery, with some paying exorbitant prices for high-quality pieces.
