Luxury scent notes are often associated with rare, expensive, high-quality ingredients. These notes can include agarwood (oud), which is a highly prized and costly wood with a rich, complex aroma. Other luxurious notes are ambergris, a rare substance produced by sperm whales, and orris root, derived from the iris flower. Additional luxury notes include jasmine, rose, sandalwood, and vanilla, often used in fine perfumery due to their rich, elegant, and long-lasting scent profiles.
