Thanks for the idea of using a glass plate. The only similar objects in my household are some glass baking dishes that are stained to various degrees from decades of use. Now that I've seen your photo, I can imagine how those stains could add attractive detail to the tabletop using lighting from below.
Rather than placing a light source above the subject because of the difficulty of doing so, consider propping up a white reflector above it. Perhaps also add some white reflectors to the front and sides areas.
For the opposite effect, consider using any white diffusion material as the background and shining a light source positioned behind it toward the subject and camera.
