modern stemware wine GLASS

I have a set of these wine glasses and not any luck so far identifying them. Any help would be appreciated.

 

Is the bottom polished?

 

The bottom is slightly concave and polished.

 

unfortunately R has this one as an unknown:

I'm a bit disappointed....lol. They're very nice heavy crystal glasses so I was hoping for something a little better. Thanks much for your help.

 

Do they refract the light?
Lead crystal then. So I would think European in origin.
Sometime in the last 20-30 years.

I first looked at Orrefors, then Mikasa and Lenox. Mikasa, Gorham and Lenox were importing glass from Europe in the 90s.

 

using image search with "R" image I found another "R" listing with these as #T3102 'Horizon' by Mikasa c1998-99; might compare size:

I really appreciate your help. I really suspected these might be Mikasa (they're similar to Park Lane) but I couldn't find the pattern. you're good at this!! Thanks!
