THE MATERIAL LIBRARY
Wood, Nuts and Seeds
A broad group of plant-derived decorative materials, not minerals.
Colors & patterns
Natural creams, browns and darker grain patterns, plus dyed finishes.
Typical origins
The species and supplier determine origin; no single country applies.
Hardness
Variable; no single Mohs value
Choosing & setting this material
The illustration shows a wood example. Confirm species, finish and stabilization. Light weight suits larger pieces, while moisture and heat may affect shape or coatings.
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.
