Isle of Wight Aurene Glass Goblet 1970s

The goblet has a blue stem which I have never seen before and can find no other examples of online.This is a scarce piece which although unsigned, was made in the tenure of Michael Harris after his departure from Mdina in the 1970s. The bowl of the goblet is a gorgeous swirling pattern of blues, browns and yellow and has a vague iridescence to the exterior (I have tried to capture this in my last photos). The stem, knop and foot rim are a lovely sea blue as opposed to the usual turquoise of the sea and sand examples.
