There is no image in your post. Try again.

I tried reposting the image on mobile. Is it showing up now?

If we click on the "?" it does appear. Calacatta. Might be Calacatta Gold but can't tell from that small sample. Research it. Matching old stone can be difficult (even newly mined stone will vary significantly at times). True Calacatta was likely mined in Italy. It's a beautiful stone but be sure you get true representative samples of the current stock available from wherever you source it, and even then, plan for variances in shade.
