The stones
core subject
It all begins with a radical choice.
Where fine jewellery turns to transparent stones, Baurocher chooses the hard, opaque stones of rare, forgotten materials with strong characters.
Each stone has a particular presence: a colour, a depth, a density that resonates with the person who chooses it.
These materials of character, and their ability to be worked in a completely new way, are at the heart of every Baurocher creation.

Grey Jadeite
Formed under extremely high pressures in tectonic subduction zones along the Motagua Fault in Guatemala, grey jadeite belongs to the pyroxene family, an extreme genesis that gives it remarkable density and hardness.
Revered by the Mayan and Olmec civilizations, who used it as a material of power and for sculpture, it carries a rare historical significance.
Its grey hue, punctuated by subtle mineral nuances, expresses a sober and assertive presence, a material that needs no brilliance to impose its character.
Snowflake Obsidian
A natural volcanic rock formed by the near-instantaneous cooling of silica-rich lava in areas of high volcanic activity in Mexico, the United States, and Iceland, snowflake obsidian is distinguished by its light-colored cristobalite inclusions, called spherulites, which appeared during partial recrystallization after solidification.
These white patterns, resembling snowflakes frozen in the dark material, give each stone a unique graphic identity. A striking contrast between order and chaos, where each piece is literally unreproducible.
Aventurine
A member of the quartz family, aventurine forms in the veins of metamorphic and crystalline rocks, where pressure and time slowly shape its texture and deep green hue.
Its uniqueness lies in its fine fuchsite inclusions, which create a delicate shimmer that gemologists call aventurescence. A light that doesn't impose itself but flows discreetly through the material. The only Baurocher stone that seems alive under the light.
Blue Chalcedony
A member of the microcrystalline quartz family, blue chalcedony forms through the slow crystallization of silica-rich solutions within rock fissures, in regions with high ancient hydrothermal activity.
Its fine, interwoven quartz fibers give it a recognizable softness and translucency due to its silky luster. Its hues, from pale blue to milky blue, evoke a calm and open presence, the only Baurocher stone that allows light to pass through.
KALKAN JASPER
A silica-rich sedimentary rock, formed by the slow accumulation of mineral deposits in Turkey.
Kalkan jasper owes its density and homogeneous structure to millions of years of compression.
More a stone of matter than of light, its naturally matte appearance and soft touch affirm a calm, almost architectural presence. Sober, deep, timeless.
MAHOGANY OBSIDIAN
A natural volcanic rock formed by the rapid cooling of silica-rich lava, it gets its deep reddish-brown hues from iron oxides integrated into the material during its formation in areas of high volcanic activity in Mexico and the United States.
Its contrasting intense black appearance and warm reflections give it a dense and warm presence, more earthy than other obsidians. A stone of strength, deeply rooted in matter.
BLACK JADE
A member of the nephrite family, black jade forms under intense pressure and high temperatures deep within the Earth's crust, a slow metamorphic process that gives it exceptional density and resistance.
Its deep black color, sometimes with subtle variations, evokes a stable, controlled, almost timeless material. A silent and assertive presence, the densest of all Baurocher stones.
GREEN PORPHYRY OF GREECE
An igneous rock resulting from the slow cooling of magma, the green porphyry of Greece develops visible crystals embedded in a finer matrix, a structure that gives it exceptional strength and stability.
Used since antiquity for the buildings and objects of power of the Greco-Roman world, it is one of the most historically significant stones in Baurocher jewelry.
Its deep green hue, punctuated by mineral nuances, imposes a calm and monumental presence – the strength expressed through mastery, never through ostentation.
White Jadeite
Formed under metamorphic conditions of very high pressure in the Kachin mountains of Myanmar, white jadeite belongs to the family of aluminum and sodium silicates, an extreme genesis that gives it exceptional density and grain fineness.
Nicknamed the "Emperor's Stone," it was elevated to the status of a symbol of imperial power during the reign of Qianlong in the 18th century. Its white to milky white hue, sometimes delicately translucent, diffuses a soft and contained light, a silent elegance, without ostentation.
A symbolic stone of Maison Baurocher, its nuances evoke the snow-capped peaks of the Alps, where it all began.
