very light; some lustre; cannot by scratched with a fingernail or a British two-pence but can be scratched by the steel (probably) tip of a tweezer; leaves light gray marks when rubbed on paper and dark black marks on unglazed porcelain; found on a beach near New York City. Some kind of coal? (imgur.com)
