Looking at the bottom of the pedestals -- In the photos, it looks like painted metal. Is it? The slab looks 'cast' to me. Again, it could just be the photos, but I'm wondering if it isn't some type of man-made 'cast-marble' product (similar to the stuff used on vanity tops) from the 1960's or 1970's? You said 'pock-marked' on the bottom -- could those be bubbles from something that was poured? Anyway - that's my guess.

Oh, heck no, and I don't think that they need to be similar in tone, either... contrast is good, lest you get the "tried to match and missed" look, which is very much not good. That goes double if you're furnishing with antiques/vintage items. I have a pretty small living room (approx 12x16 if we're being optimistic!) and not one thing matches anything else. The coffee table is nutmeg-stained maple, rectangular with porringer corners and big drawers, sort of country-Victorian-inspired. One side table is a 30" round tea table in cherry-stained quartersawn oak in typical reproduction Mission style. Another is a small antique Arts & Crafts period 16" round tabouret table, quartersawn oak in a chocolatey brown finish (fumed oak). The last is a little bitty 12" square blonde ashwood table with slightly curvy legs, rather more modern than the other items although I'm keeping my eyes peeled for a certain style of mahogany or walnut Victorian bookstand end table to come along in-budget (aka cheap LOL). I have a large backless upholstered bench that's too modern in style for this old house and is on my list of things to sell - once I do I plan to replace it with a wing chair and I think the small copper-topped fumed-oak trestle coffee table would fit underneath the window next to where the chair would go. What makes everything play nicely together is that it's all from (or reproduced from) the same time period, the turn of the 19th-20th century.

dilly_dally, you don't need to oil wood furniture - in fact, oil even attracts crud and dust so it kind of defeats the purpose. A barely-even-thinking-about-being-damp rag or microfiber cloth makes short work of dust. As for any scratches on a wood tabletop, Old English Scratch Cover is a gift from the gods. Wipe on, wipe off. One of my various glass coffee tables was a wood-frame-glass-inset and others do make the very good point of crud collecting in that seam between the glass and the wood. (I can clearly remember three, one "glass oval on brass metal base", one oh-so-1980s "glass square in oak table", and one "rectangle of beveled glass on iron base" which lasted about two weeks before going back out onto the curb because I kept smashing my shins into those very sharp corners. There may have been more. I've moved so many times and cycled through so much Gift of the Garbage Goddess furniture that I can hardly remember it all!) FWIW, for scratches in glass surfaces, there are special polishes with fine, fine, fine abrasives that you can use to buff scratches out of glass. Automotive supply stores, good hardware stores, and (obviously) glass shops should have a selection of products. Too much hassle for me but it might be just the thing for some of you. :-)

Do you have a picture of the coffee table? I don't see it posted here. Normally, the legs would have to be taller than an average height coffee table.
