blue and wire decanter set

this is a blue glass decanter with 6 cups,  they all have some very detailed silver colored wire patterning wrapper arround them, I found it in my great grandmothers garage while cleaning it she has no idea where it came from. i can find m=no stamps or markings on the set at all, the bottom of the cups have several small circle rings in the glass. There are some small inperfections arround the rim of the cups.

Good
