There is only one stone in the world capable of fusing amethyst's violet with citrine's gold in a single crystal: Ametrine. Here's what makes it so unique.
What is Ametrine?
Ametrine is a variety of natural bi-colored quartz (untreated and undyed) that combines, within a single crystal, the violet zones of amethyst and the golden-yellow zones of citrine. This color zoning is caused by differences in the oxidation state of iron within the mineral, generated by temperature gradients during its geological formation.

Why does almost all ametrine come from Bolivia?
Practically 100% of gem-quality ametrine comes from the Anahí mine, in the Santa Cruz department of Bolivia. Legend has it that a Spanish conquistador received the mine as a wedding dowry from an Ayoreo princess named Anahí, who revealed its location. Today, along with a few minor deposits, it remains the world's almost exclusive source of this gem.
Meaning and Energy of Ametrine
Ametrine combines amethyst's spiritual, protective energy with citrine's vitality and abundance. Associated with the solar plexus and crown chakras, it stimulates creativity, strengthens willpower, and harmonizes mind and spirit. It's the ideal stone for those seeking balance between the material and the transcendent.
How to Care for Your Ametrine
- ✅ With a hardness of 7, it's suitable for everyday use in rings and pendants.
- ✅ Clean with warm water and mild soap, drying with a soft cloth.
- ❌ Avoid exposing it to extreme heat or sudden temperature changes: this can affect the sharpness of the color zoning.
- ❌ Avoid ultrasonic cleaning if the piece has visible inclusions.
