Ametrine is a variety of quartz and is prized for its striking color zoning, where the purple of amethyst blends with the golden-yellow hues of citrine. This dual-color effect occurs naturally due to temperature variations during the crystal's formation.

Ametrine is primarily sourced from Bolivia and is admired for its beauty and metaphysical properties, believed to enhance creativity and balance emotions by combining the energies of both amethyst and citrine.
