I'm not sure what it is. Any of you ever seen anything like this. It's about the size of a 1/8 watt resistor.

Diode...

Thank you. I just checked it, and it does act like a diode. The glass case thru me. And it came wrapped in foil, as if it were light sensitive.

yeah glass diode, could be germainium, check the vdrop

With a AA battery(1.53v) Diode reads .95v one way and 1.49v the other way. Does not seem correct?

You just shorted it across a AA battery? That can deliver amperes of short circuit current? To a signal diode?

I'm amazed it didn't blow. Well, depends... if you measured reverse first, maybe the next time, it won't give the same result...

note that he specified 1.49 the other way.
either the battery is recovering from a short, or the diode is leaky.

That's the great thing about glass diodes, in a pinch they can be briefly turned into a LED.

They are light sensitive. Not sure what you mean by "With a AA battery", but I hope you know what the I-V curve of a diode looks like...
