Se define como la relaci\u00f3n entre la velocidad de la luz en el vac\u00edo y su velocidad dentro de la gema. Por ejemplo, el IR del diamante, de 2,42, ralentiza significativamente la luz, creando su brillo caracter\u00edstico. Por el contrario, el cuarzo (IR ~1,54) permite una transmisi\u00f3n de luz m\u00e1s r\u00e1pida, lo que resulta en un brillo m\u00e1s suave.<\/p><div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div><h2 class=\"wp-block-heading has-text-color has-link-color wp-elements-6977961fb4b6b2e698d47f19e523a066\" style=\"color:#7594a3;font-size:25px\">\u00bfPor qu\u00e9 var\u00eda el \u00edndice de reactividad?<\/h2><p>El \u00edndice de refracci\u00f3n (IR) se rige por la estructura cristalina y la qu\u00edmica.
