"Golden Amethyst"

Ametrine, a captivating gemstone and a variety of quartz, uniquely showcases the contrasting yet complementary colors of amethyst and citrine within a single crystal, a stunning natural phenomenon where violet and golden hues blend seamlessly or sharply demarcate, making it a prized gem for collectors and jewellery enthusiasts alike. This bi-coloration arises from a fascinating geological process wherein quartz crystals with iron impurities are subjected to varying temperatures during growth; the presence of iron in different oxidation states, influenced by these temperature gradients, results in the purple of amethyst and the yellow to orange of citrine within the same crystal structure. This delicate balance of conditions, maintained over a prolonged period within hydrothermal environments, is relatively rare, making natural Ametrine a unique treasure often exhibiting parallel colour zones, sometimes with a clear quartz section in between, with the most prized specimens displaying a balanced and distinct distribution of both colours. While minor occurrences have been reported in Brazil, Canada, and the United States, the Anahi Mine in Bolivia stands as the world's primary source of gem-quality Ametrine, located in the Santa Cruz department near the Brazilian border within the Bolivian Ametrine Belt, boasting the specific geological conditions required for its formation, a mine legendarily discovered in the 17th century and rediscovered in the 1960s, bringing this exceptional gemstone to the modern market, leading Bolivians to proudly consider it their national gemstone, sometimes referring to it as "Bolivianite."
