Featured Purple opalescent glass tumblers - ground polished pontils Where from?

Picked up this set of 6 the other day - They stand about 6" tall. The pontils are ground and polished. They look dark purple - kind of a medium lilac color when you hold them up to the light. They have an opalescent webbing and the upper 1/4 of them near the rim is opalescent as well. Where might these be from? There is some wear to the bases from use - at least a number of years worth I would think.

Thanks again!

No Joy here, sorry. Again, my knowledge stops around 1900 (with exceptions.) These are last half 20th.

 

They remind me of giraffe markings. Pretty,Id have bought them but I do think they arent very old.

 

it's bar ware...but only to be used once you're already drunk...

 

I was told once who made them, but I forgot. They are modern.

 

Thanks Fenton!
