Physical properties
Opaque pale green with dark veining and a polished, waxy luster; serpentine has Mohs hardness about 2.5–5.5 and a variable, fine-grained structure. The exact material cannot be confirmed from the image alone.
Formation & geological history
Serpentine forms when water alters magnesium-rich rocks, commonly in ancient oceanic crust and mantle-derived ultramafic rocks; the heart shape is carved and polished. Geological ages depend on the deposit.
Uses & applications
Used for ornaments, carvings, beads, and decorative stone; this small heart is primarily a jewelry or gift item.
Geological facts
The dark lines may be natural mineral veins or fractures accentuated by polishing; “serpentine” refers to a mineral group and to rocks rich in those minerals.
Field identification & locations
A waxy feel, relatively low hardness, and pale green color can suggest serpentine, but similar-looking stones include jade and dyed materials. Serpentinite occurs in many mountain belts worldwide.
