New acquisition black carved Carrera marble vase with two would appear to be bronze mounted detailed base

I hope this finds everyone well. I recently purchased this item on Facebook Marketplace, the only picture that I can find or information is number 4 in my photos is the only information I've been able to find about this .I would greatly a appreciate any help that anyone could offer me ,if you look on the picture of the bass that it sits upon if you look from 7 till 2 on face it appears there's a signature there in a date. I'm unable to clearly see it. The vase itself is 16 in tall 8 and 3/4 inches wide at the widest point oh, and the base it sits upon is 11 in corner to corner. Thank you in advance for your help and time.
