Glass Identification: Grape Pattern (?) Amber Glass Help

Q:
I am told that a set of these glasses came from grandma's collection and that's all I know. The picture can tell you more than I can. 5 1/2" Tall

A:
Hi - What a beautiful & unusual piece. It is not a Depression Glass pattern - I suspect it is from an earlier era than that - maybe the late 1800s or early 1900s - just a guess. You may want to look for some antique glass identification books or resources. Or maybe someone else will be able to identify it.
