As with anything else you buy on eBay (plants, for sure) you take a chance.
What more can I say?
Actually, one of the reasons these usually fetch a good price on the used
market is that they are relatively abuse-resistant. It's nearly impossible
to crash the objectives since the working distance is several inches
instead
of microns and even if you actually drop it, not too much is damaged since
the optical path is relatively insensitive to misalignment.
You might want to examine your amber jewelry for minute arthropods that
may
have gone unnoticed - but don't look too closely at your other jewelry.
