Optional details you know first-hand
Tell us what you measured yourself, what someone told you, and what a report says — we keep these separate.

Questions
Can a photo measure hardness?
No. We can quote reference ranges for a species, which is different from a property of your specimen.
Should I do a streak or scratch test?
Only record tests you or a qualified person have already performed; we won't instruct destructive tests on unknown specimens.
