Help with large blue stone in brooch

[wessleysbest]

This is an unmarked 2" long brooch with dogtooth set rhinestones around a robin's egg blue stone with "veining" that may be actual stone or glass, I don't know.    Help!  Thanks for looking.

Beautiful!

I think your stone is an Art Glass Faux Turquoise. A kin of Art Glass Peking Glass.
