Two Stones in One

Ametrine is a single quartz crystal that displays both amethyst's violet and citrine's gold within the same stone — a natural curiosity caused by uneven heating during the crystal's formation.

Gemologically, ametrine is described as transparent, with a vitreous luster — qualities that shape how it catches and carries light once cut. Its colour comes from iron, with uneven heat distribution during formation creating both colour zones, and a Mohs hardness in this range is durable enough for regular wear, though it benefits from being set thoughtfully and kept away from harder gems in storage.

Where Ametrine Comes From

Folklore and Healing Traditions

Ametrine has held a place in decorative arts, folklore, and crystal-healing traditions across cultures for centuries. Those drawn to this dimension of the stone often choose it for its colour and character as much as for any tradition attached to it — a personal, rather than prescriptive, choice.

How Ametrine Is Graded

Quality in ametrine is generally assessed across colour, clarity, cut, and carat weight — with colour and overall character typically the dominant factors in value.

What a Lab Report Confirms

A lab report identifies the species, describes colour, and discloses any treatment. Natural ametrine is untreated by definition; lab-created and partially-heated material is common and should be disclosed.

Natural, Ethical, Jaipur-Sourced

Every ametrine in the Paraiso Jewels vault is described accurately as to its natural or treated status on its label. We source through Jaipur's gem market — one of the world's oldest and most concentrated coloured-stone trading centres — and our stones can be verified at GTL Jaipur, the region's principal gem testing authority.

On request, each piece can be accompanied by documentation covering weight, dimensions, and treatment status. If you have questions about the origin or treatment of a specific stone, contact us via WhatsApp or email and we'll provide full details.
