O teste do laser é um dos jeitos mais simples de identificar um diamante verdadeiro. Isso porque o diamante tem um alto índice de refração: quando o laser entra, a luz se espalha por dentro e não sai em linha reta do outro lado — formando um brilho difuso típico da pedra. Já pedras falsas, como vidro ou zircônia cúbica, deixam o laser passar quase direto, sem essa dispersão característica.
