Any info on Glass Tumblers

Are these glasses/tumblers old? Brilliant cut? Why are the patterns the same but not exact in measurement of pattern placement on glass. Any info would be appreciated.

Sorry, cannot determine age based on your photos.

I would call these copper wheel engraved...the cutting is hand done so you would expect variation.

Crystal? If you flick the rim of a glass with your fingernail do you hear a ring?
