Nice Studio Vase, in porcelain? Green glaze

I like this, the form is nice, it looks spontaneous. I think it's porcelain.
The Glaze has a nice shimmer in the light. The mark is very hard to see and picture.

Dimensions to follow, if need be.
Thanks for any help.

I think there’s a G in the mark but need a closeup to see the rest. Stoneware rather than porcelain imo

It's so difficult to make out. I'l try my best to picture it.

I don't think it's any easier to see the letters in real life.

Here's hoping that someone might recognise the shape of the mark, from a different piece by the same artist..
