Black Marble Oriental Vase 20+++ years??

I have a black oriental in appearance vase which I purchased in around 1993 from an estate sale when I was a youth from a woman who did not know it's origin as it was her late mothers.  There is what appears to be symbols of a language wrapped around the vase on top of the pictures which are finely etched into the side of this beautifully detailed stone/marble vase.  A charriot with a passener and driver as well as horses and what looks to be guards are etched below the symbols.

Good
