Black Galaxy questions
Is Black Galaxy in stock as a full slab?
Yes. Black Galaxy is stocked as full slabs at our West Allis slab gallery near Milwaukee, so you can see the complete piece — and how the pattern runs across it — before you commit. Stock moves, so call 414-998-0404 to confirm current availability.
Does Black Galaxy need to be sealed?
Yes. Black Galaxy is natural stone and porous, so your fabricator applies a penetrating sealer after installation and it is refreshed periodically. Granite handles heat well, so hot cookware is not a problem.
What is Black Galaxy best used for?
Kitchen countertops, islands, bar tops, outdoor kitchens and fireplace surrounds. Granite's heat resistance makes it a common choice where hot cookware goes straight onto the surface.
Can I buy Black Galaxy if I already have a fabricator?
Yes. Come to the gallery, tag the granite slab you want, and your fabricator collects it. We also sell directly to fabricators, builders and remodelers across the Milwaukee area on wholesale terms.

Black Galaxy — Full-Size Slab Photographs
Photographs of the actual Black Galaxy slabs at full resolution, shot on the rack rather than rendered.
Colour on a screen never matches the slab under warehouse lighting. Check live inventory or see it at the West Allis showroom.
Black Galaxy in Kitchens and Bathrooms
Three design visualizations showing how Black Galaxy reads at room scale: as a full-height kitchen backsplash, on a bathroom vanity, and on a waterfall-edge island. Each one was generated from the photograph of the actual slab on this page, so the natural stone pattern, colour and finish match the stone we stock in West Allis.
Please note: these three images are digital visualizations, not photographs of completed installations. For photographs of the real slabs, see the gallery above. Natural stone varies slab to slab — check live inventory or view your piece at the West Allis showroom.
