Exquisite Diamond Crystal Perfume Bottle w/ Stopper

This is a beautiful old heavy crystal perfume bottle with the stopper. It has a diamond pattern and sanded stopper and inside of the bottle neck. It measures 6 and 7/8 inches hight and 2 inches in diameter. It is in excellent condition, no chips and no cracks. This is an auction item, I don't know the age or maker but it looks like an older piece.
