Aurora Borealis is quarried from boulders in the state of Espirito Santo, Brazil. This particular granite is a limited production color. Over millions of years, water has penetrated deep into the stone through small cracks and fissures, causing the iron oxide and other minerals to oxidize. This process produces the rich, vibrant gold tones that are visible in this granite. Due to its qualities, the slabs are book-matched, in which slab one and slab two will be cut and polished to create a mirror image of each other. These are then kept in sequence, which allows for a consistent flow in pattern. During the polishing process, an epoxy resin is applied to the surface of the slabs to fill in these natural pits, cracks and fissures existing in the stone. This does not affect the durability, maintenance or beauty of the slab. It is possible for some of the more minute pits that are too small to effectively hold the resin, to reopen during other finishing stages. However, this will not detract from the overall quality or appearance of the stone. As a natural stone product, it is recommended that this be sealed to extend its longevity.
This granite is also known as Dunas Purple or Purple Dunas, Galactica, or Golden Lumiere.
