Natural Ametrine – Bi-Color Gemstones in Violet & Gold

What is Ametrine?

Ametrine is a natural, bi-colored variety of quartz that beautifully combines the deep violet of Amethyst and the golden glow of Citrine in a single gem. This phenomenon occurs when different oxidation states of iron form in separate zones of the same crystal during growth.

Why Choose Ametrine?

Each Ametrine gemstone is truly one of a kind — the unique balance of warm and cool tones makes it a favorite for designers and collectors alike. The interplay of colors can be soft and dreamy or boldly contrasting, depending on the orientation and cut.

A Rare Member of the Quartz Family

Ametrine belongs to the Quartz family, along with other beloved gems like Amethyst, Citrine, and Rutilated Quartz. Naturally occurring Ametrine is sourced almost exclusively from Bolivia, making it rare and desirable among colored stone enthusiasts.
