When I ran across this pretty blue piece I knew I had seen it somewhere and lo and behold it is featured (kind of) in Gene and Cathy Florence’s book – American Pattern Glass table Sets. The pattern is Open Rose a/k/a Moss Rose.
However this is a Mosser Glass Company reproduction of the original nineteenth century crystal piece. According to the Florences the original manufacturer is unknown.
Mosser reproduced spooners and goblets in amber, crystal and green as well as this blue.
It is a pretty piece, although not so old.
