Marble Ashtray

I’m not 100%.Sure, this is alabaster, marble or what this is, but it’s old, it’s kind of heavy, and it’s very nice.There is no markings on it as well, so I’m thinking it is a ashtray and maybe like alabaster or marble or a marble design.This is just sold as is really no knowledge of it , but it’s really nice I’M NOT 100%.SURE WHAT THE BRAND IS EITHER SO THIS IS SOLD AS IS HOPEFULLY , SOMEONE’S KNOWLEDGE WILL KNOW EXACTLY WHAT THEY’RE GETTING
