Pewter is in the "silver" family. Antiqued is usually a bit darker than non-antiqued pewter. Personally, I think the antique pewter will look fine with the black galaxy - as long as the gold flecks are not overpowering (and they should not be in true black galaxy.) We toyed with that granite as well, but in the end decided the copper flecks would clash with our cherry cabinets. (The black galaxy we saw back in 2008 had a mix of gold & copper flecks. We did not have a problem with the gold, just the copper.) We have pewter pendants, antique iron drawer pulls & door knobs, SS appliances, and satin nickel fixtures - all very similar to your choices and we thought the gold flecks would be fine with our choices. HTH!

Check the absorption rate...I think you'll find it's too dense to take a sealer (absorption rate From the Stone Advice thread (linked in the "Read Me" thread): BUT: Not all stones need sealer either. Stones like Blue Pearl, Ubatuba, Black Galaxy, Verde Peacock, Verde Butterfly, Platinum Pearl and many others are too dense to absorb any liquids - sealers included. Sealers only protect stone from staining through absorption, so in stones with low absorption coefficients, sealing would be superfluous. Sealing dense stones could lead to nasty results, such as streaking and ghost etching, so DO NOT go by the motto of "seal it anyway, it could not hurt". Rather test your stone for absorption by dripping water on it to see if it darkens any. If the water has no effect on the stone, sealing it is unnecessary.

I use a remnant of it for a bathroom vanity (the store called it "Blue Polare". I loved it so much that when I wanted to renovate two other bathrooms, I searched at least 15 other granite companies. Only one had even a full slab to look at, but no remnants. Most of the salespeople said it was quite rare, thus so costly. If I had LOTS of money, I would definitely put it in my kitchen and other areas. I did find a remnant of Blue Volga for one bath....it has those beautiful irridescent blue-green pieces in it, much like Blue in the Night has the blue. I just think there is just no comparison between the appearance of Blue in the Night and black galaxy, IMHO

I have polished AB and when I want a shiny finish, I use Method granite cleaner, when I can get it. I use Simple Green when I can't get Method. Usually, though, I just use detergent & water and, yes, it does get a detergent haze on it! For everyday use, though, I don't care. But when I have company or just feel like a shiny counter, I use the above products.
