Whale bone is a material of a different nature than sperm whale tooth: not dense dentine but true bone tissue, lighter, more porous in structure, and warm to the touch. Historically whale bone was widely used by sailors and carvers of coastal cultures, and it carries a distinct maritime character. The law requires the same precision as with other whale materials: the great whales are protected under CITES, international trade is strictly limited, and only old, antique, or subfossil material with documents of origin can be legal within a given country's rules; new demand is indefensible. The colour of whale bone ranges from cream-white to warm ochre, with visible bone texture and fine channels that the maker reveals through polishing. In the hand the material is noticeably lighter than dentine, warm almost at once, with a soft, faintly breathing surface — a feel quite unlike a dense tooth. Spun, it sounds soft and muted, without ring, a warm dry tone — bone has a calmer voice than tooth. Patina takes readily, a warm honeyed shade that emphasises the natural texture. Care is more attentive than for dentine: bone is more porous, so it is especially important to protect it from moisture, direct heat, and sun, and to wipe it only with a dry soft cloth. These beads suit those who value lightness, a warm living texture, and the maritime history of the material, treating its origin with due respect and caution.
