The flower frog in which the figurine sits is said to be hand cut crystal so as to replicate ice.
The figurine of this flower frog has been seen in crystal, blue and pink, other colours are possible.
This flower frog had been attributed to the Riedel Glass Works who were a Czechoslovakian glass company, however this could not be confirmed.
Recently I acquired the 1971 publication pictured below.
I have found it to be an amazing resource about the STUBEN
Art Glass of Frederick Carder.
The flower frog is pictured and named Diving Girl with the No 6483 on page 92 pictured below.
