Citrine is a type of quartz mineral that differs from ordinary quartz only in color. A relatively inexpensive semi-precious stone. The name comes from lat. citrus - lemon yellow Color from light lemon to amber honey. Transparent. The color of citrines is due to the transition from ferrous iron to ferric iron, or the presence of impurities of ferric iron, which is in the quartz structure in the tetrahedral position, or is associated with defects arising from the replacement of tetravalent silicon by ferric aluminum with compensation of valence by lithium and hydrogen ions. Fractured crystals and muddy stones with inclusions are cabochon cut.
