Value guidance
Collector specimens are normally expected to have meaningful collector value, often in the region of £750–£1,000+ retail equivalent — though rarity, provenance, locality or mineralogical significance can justify inclusion below that. This is guidance, not an automatic qualification threshold.
Identification & provenance
Mineral identification, locality, provenance and condition information are supplied by the listing dealer and reviewed by Chaos for marketplace suitability.
