Ametrine displays a unique blend of citrine and amethyst within a single crystal, resulting from differing oxidation states of iron impurities during its formation. This characteristic dichroism, the ability to exhibit two colors depending on the viewing angle, creates a striking visual effect ranging from vibrant golden yellows and oranges to deep purples and lavenders. Natural ametrine is primarily sourced from the Anahi mine in Bolivia.
This rare gemstone is prized for its aesthetic beauty and is believed by some to combine the energizing properties of citrine with the calming influence of amethyst. Historically, indigenous Bolivian cultures valued ametrine for its perceived spiritual and healing attributes. This historical significance, coupled with its limited availability, contributes to its desirability among collectors and jewelry enthusiasts.
