This particular antique glass cake stand is called Jacobs Ladder and we can see why from the stair step design shown on the plate. The rims is gently scalloped and the step design repeats itself on the base.
Manufactured by Bryce, Walker and Co. , this particular pattern dates to c. 1876.
Measuring 9 inches diameter on the plate and stands 5 inches tall. We do not see a bit of damage to this!
