Heavy Cut Crystal Decanter with Stopper # 10978

This is an unmarked heavy (2.10 lbs) Crystal Decanter with a stopper. The decanter has no markings or tags and I have added pictures of cuts or scratches because I don’t quite understand them. It is almost like it was carved from the inside. I’ve had a lot of suggestions on what could have caused this, but I’m not sure. The decanter measures 5 7/8 inches tall or is 7.50 inches with the stopper. It is 4.25 at the widest point and about 3.00 inches deep. The decanter has been cut to clear on the body in large arches from the base up. It has actually cut on each of the four sides and then again in between those cuts. The stopper is large and flat cut on all sides and is a perfect fit. With the exception of these scratches, the bottle has no damage. The base is thick and clear, and it looks like it is made to house something expensive. Weight before packing is two pounds, ten ounces. See more at Debsellstoyou. Item:10978 Location # 4/2
