The preview is an example of a render you can create using the high-resolution file of Kuroca quartzite in the NFT. Kuroca is a black quartzite from Angola owned by Nikolaus Bagnara S.p.A., a family-owned business from Appiano Italy who started their company way back in 1948. The file is a high-resolution photo of a real quartzite slab of this natural stone, so it is unique and has a one-of it`s kind vein pattern. Each preview of this collection is a different render example of how the file could be used and contains the original high-resolution image. Each original file is similar in all 6 NFTs. We are using this collection to test the interest of the designer community for such unique digital copies of real-world material products. The render could be for interior design renders for the real world or for your #metaverce property interior. This slab was already sold and will be used for a kitchen top or other decorative elements in someone's home. If successful, we will help the stone owner to promote more beautiful material from their quarries with the possibility of shipping the physical version of the stone slab to the NFT buyers for additional payment. All rights for this collection sale have been granted by Nikolaus Bagnara S.p.A.
