Physical properties

Formation & geological history

Likely naturally weathered sediment transported by water or ice; exact geological age and parent rock are unknown.

Uses & applications

Primarily a casual specimen or decorative pebble; no reliable industrial or jewelry use can be assigned without identification.

Geological facts

The image is too low-resolution and lacks scale, translucency, texture, and diagnostic features for a confident mineral or rock name.

Field identification & locations

Test unglazed porcelain streak, glass-scratching ability, magnetism, and acid reaction; inspect with a loupe for quartz grains, feldspar, or cleavage. Commonly found in stream or glacial gravels.
