Chrysocolla vs Turquoise: 7 Key Differences to Spot & Choose
Chrysocolla is a bright blue-green copper silicate; turquoise is an opaque blue-green copper aluminum phosphate. Both owe their color to copper, but they are distinct minerals with different chemistry, hardness, and value.
Shoppers, collectors, and TikTok crystal sellers often confuse them because they sit side-by-side in souvenir bins and Instagram flat-lays. One costs $5, the other $500, yet the untrained eye sees only “pretty aqua rock.”
