Green Crystals

What Makes Minerals Green?

Green is the most common color in the mineral kingdom because the two most abundant transition metals - iron and copper - both commonly produce green. Iron in its Fe²⁺ state (as in olivine and epidote) absorbs red light, transmitting green. Copper compounds (malachite, chrysocolla, dioptase) achieve green through different electronic transitions. Chromium, though rarer, produces the finest greens: the pure green of emerald and chrome diopside.
