Description/Interesting Notes: A rare, old time example of greenockite from the type locale in Scotland!!! This specimen hosts a single, complex crystal of intense yellow greenockite on a characteristic prehnite matrix!!! Upon close inspection with a loupe or scope one can see lustrous crystal faces and well defined crystalline features!!! These historic specimens were discovered in 1840 while cutting a railroad on the property of Lord Greenock, for whom the species is named!!! These specimens are quite scarce today!!!
