I have waited a suitable time since Anik's post to post this

I'm stuck. It has lots of age wear to the base, so that if there were ever a sig it would not be there now.
It has a gently curved inwards base to a beautifully finished snapped off pontil mark, clean, smooth and just a crease on one side of it.
It is a gorgeous colour I have to say - definitely 'citrine' I would think. It's about 10.5cm high by 9.5cm wide.
Any help much appreciated - ideas etc. Could it be Italian?
Many thanks
