I suggest you find a local stone fabricator. If you are in the Denver area we would be more than happy to help you in your selection. I say this due to the number of factors that come into play. Some factors are the particular material you may be interested in using, whether your existing table base will be sufficient or if you need a new table base (this may also depend some what on the particular stone you choose to use as well as the shape and size of the table).
