Large Tortoiseshell Glass Vase

This great tortoiseshell vase is just under 12 inches tall with an opening of about 3 inches in diameter. It is in excellent condition with no large cracks or chips; there is a small flea bite (pictured) on the side, and some internal cracks on the bottom of the glass,  it looks like it could be leftover likely from the time of it’s manufacture when the vase  would have been broken off the blowpipe.
