Dyed pink stone, likely rhodonite or dyed howlite/magnesite

Rhodonite: MnSiO₃; possible howlite: Ca₂B₅SiO₉(OH)₅

AI-generated identification · may be incorrect

Opaque, vivid magenta-pink with black inclusions or veining and a polished/waxy luster. Rhodonite has Mohs hardness 5.5–6.5; howlite/magnesite is softer, about 3–4.5; crystal structure is typically obscured in tumbled pieces.

Physical properties

Formation & geological history

Rhodonite forms through manganese-rich metamorphism or hydrothermal alteration, commonly in Precambrian terrains. Howlite forms in borate-rich evaporitic environments; the bright pink color may be artificial dyeing.

Uses & applications

Used as a tumbled ornamental stone, cabochon, bead, or low-cost jewelry material; not generally used for construction.

Geological facts

Black manganese-oxide veining strongly favors rhodonite, while uniform neon color and pale porous interiors suggest dyed howlite or magnesite. Acid and hardness tests can help distinguish them.

Field identification & locations

Common sources include Australia, Russia, Peru, South Africa, and the United States for rhodonite; dyed white howlite/magnesite is widely sold from commercial lapidary suppliers. Typical value is $2–$15 for a small tumbled piece, or $20–$80 for attractive larger material.
