Patagonia Granite has large crystals of feldspar, quartz, and biotite. Because of the unique structure of these crystals which can cause voids, during the polishing process an epoxy resin is applied to the surface of the stone to fill in any natural pits. This does not affect the durability, maintenance or beauty of the stone. This stone ideal for the customer looking to make a statement and who recognizes its beauty. Perfect for an accent wall, kitchen countertop or bathroom vanity.
