Ametrine is a rare and captivating gemstone known for its unique combination of amethyst and citrine colors in a single stone. This natural phenomenon occurs due to varying oxidation states of iron within the crystal structure, creating zones of purple and yellow or orange.

With a hardness of 7 on the Mohs scale, ametrine is durable and suitable for various types of jewelry, including rings, necklaces, and earrings.
