The material, examined
What the name tells you
Rounded aggregates can conceal individual crystal form. Look at the whole specimen—including matrix and neighboring minerals—before identifying a polished piece from its pale green alone.
A useful question at the counter
Is the green host established as prehnite, and what evidence identifies its inclusions?
A note for your collection
Protect brittle pieces and cleavage surfaces from knocks. Use gentle cleaning rather than aggressive mechanical methods.
