Big Black Tourmaline Crystal Coloring Page

Multiple striated columns extend upward from a chunky mineral base, with each hexagonal prism showing vertical parallel lines running from tip to foundation for this coloring page. The tallest central crystal tower reaches significantly higher than its neighboring columns, creating a natural pyramid-like composition. Angular rock chunks form the irregular foundation, their broken facets and rough edges contrasting sharply with the smooth vertical striations above. Each vertical line groove on the crystal surfaces needs consistent pencil pressure to create realistic depth and dimension. The rocky base sections benefit from darker shading in the crevices between fragments, while lighter values on the crystal faces will emphasize their reflective quality. Try graphite or gray tones ranging from charcoal blacks in the deepest grooves to pale silver highlights along the raised edges of each striated column.
