Both covers of the Indescribable Lore lexicon have two elongated, violet diamonds on them. They also have four pale pink crescents arranged into an "X" pattern around the diamonds. There is a short, wide, white diamond on either side of this "X", and four violet triangles on the spine of the book, two large ones and two small ones. All of the shapes on the spine and covers, as well as the lexicon itself, have black borders.
