It is nice but way too big for the space so I want to sell it. Can't sell if I don't know what wood it is.Not sure but it looks nice. Weight is not a good way to tell unless you can do a good density calculation (requires volume of material as well as precise weight). Man made materials like plywood and particle board (or MDF) are heavier than solid wood (normal species anyway). A table built with a MDF or particle board core veneered in mahogany would be heavier than one with a solid mahogany top.
Based on the photo, Grain not color, I would say Cherry.
