THE MATERIAL LIBRARY
Bone and Horn
Organic animal-derived materials, rather than gemstones.
Colors & patterns
Bone is often cream or ivory-toned; horn may be brown, black or translucent amber.
Typical origins
Origin depends on the species, supplier and place of processing; there is no single mining source.
Hardness
Variable; not a single mineral
Choosing & setting this material
The illustration shows a bone example. Confirm species and sourcing, and whether the material is dyed or stabilized. Best used in lightweight pendants or earrings.
Care & cleaning
Wipe gently with a soft, slightly damp cloth and dry promptly. Avoid soaking, acids, solvents, steam and ultrasonic cleaning. Store separately to protect the surface.
Origins above describe typical sources of the material, not the origin of an illustrated or stocked stone. Hardness measures scratch resistance, not resistance to breaking. Confirm the identity and treatments of the actual piece.
