I wonder if anyone (Ivo? as you have been so helpful?) can help with this large tortoiseshell vase? It is thick and measures 30.5cm (high) by 7.5cm (diameter).
I thought it was simply tortoiseshell until I got it home and could see a chartreuse swirled through it visible most at the base and in the body as little tiny spots mostly on two sides.
I hope the pictures might help but, as a beginner, I am not always taking the best shots.
Yours sincerely,
Ian
