How to Identify Garnets
Garnets form 12-sided (dodecahedral) crystals — little faceted balls in red, brown-red, or orange — with a glassy luster, hardness 6.5–7.5, and no cleavage. They resist weathering, so intact crystals roll free of rotten rock. A streak of dark red sand in a creek bed is often garnet concentrate announcing a source upstream.
