An Auvergne sapphire at the heart of a flower of forty diamonds
Made to order: delivery within 5 weeks in France, 7 weeks internationally
Gentiane is named after a wildflower of the mountain pastures of Auvergne, in central France, the region its sapphire comes from. At its center sits a 0.45-carat Auvergne sapphire, unheated and untreated; around it, an eight-pointed star-shaped head holds a first halo of eight diamonds, then a second of thirty-two.
Designed as an engagement ring, it can also be worn on its own, every day.
Usually small, Auvergne sapphires were carried toward the surface by the volcanic activity of France's Massif Central, then concentrated in river gravels, especially around Le Puy-en-Velay. The one in Gentiane was recovered during an expedition, then cut in Auvergne; unheated and untreated, it keeps its natural color.

Color may vary. Unheated and untreated, each Auvergne sapphire keeps its natural color, somewhere between green, yellow and blue. Every stone is unique: the ring is made subject to the sapphires available in our workshop.

The Story
Gentiane is named after a wildflower of the mountain pastures of Auvergne, the region its sapphire comes from. Its eight-pointed star-shaped head holds two halos of diamonds and, at the center, a 0.45-carat Auvergne sapphire, unheated and untreated. An engagement ring that can also be worn every day, shaped and set by hand in our workshop in Saumur, France.

We did not choose the color of this sapphire: we left it just as Auvergne made it.
Unheated and untreated, every Auvergne sapphire keeps its natural color, somewhere between green, yellow and blue. The color of your stone may therefore differ from the photos. Each ring is made subject to the sapphires available in our workshop.
A natural diamond is mined from the earth; a lab-grown diamond is made by people, in a laboratory. Both have the same composition and the same hardness. Both are offered for the halos of Gentiane; the center stone is always a natural Auvergne sapphire.
