@foreverroxjewelry: Would you believe that a diamond can change colors. Not in a metaphorical sense — it literally shifts from one color to another when exposed to heat or darkness, and then shifts back. Scientists have been studying this for over 150 years. They still do not fully understand why it happens. And the stone is so rare that researchers have had genuine difficulty finding enough specimens to study. #chameleon #diamonds #finejewelry #gemology #raregems
