The piece stands 10 1/4" tall with stopper and 9 1/8" without stopper. The stopper has markings on the bottom of it, while i can not find any markings on the decanter. There are no chips or cracks, the very bottom clear area has some white cloudy residue, or it could just be slightly cloudy from liquid being left inside for many years.
The sides looks clear, so it is just on the very inside bottom, i can not reach in there, have nothing to work that area with. Please see pictures, sorry for the glare, the color is a cobalt blue even though there is a purple tinge in the photos, it is not , in person it is blue.
Thank you for shopping with us, please feel free to ask any questions or if you require more photos, and any ideas on how to get in that bottom and clean the bottle or attempt to clean it out.
