Because the brown corundum contains Fe (iron), the quality of brown corundum can be differentiated by color.
The color of brown corundum is usually brown and transparent. The color of brown corundum with high aluminum content is lighter, and the transparency of shiny brown corundum in the sun is very high.
The depth of color is closely related to the size of particles. The smaller the particles of brown corundum, the lighter the color.
