From rough stone to set jewel

Stones chosen at the source, cut by hand, then set at the bench pin of my workshop. For lapidaries, collectors and jewellers.

Cutting at the workshop

A cut calculated, not guessed

Every stone I cut is first modelled in Facet Lab, 3D design software for gemstone cuts. The angles, number and position of the facets are calculated for the refractive index of each material, and the path of light is simulated before the stone ever touches the lap: the result is a very high-precision cut and optimal brilliance.

In mining countries (India, Sri Lanka, Brazil, Madagascar…), many stones are cut to keep as much weight as possible, since they are sold by the carat. Here, the cut serves the brilliance of the stone, not the scales.

I Never dark

Poorly chosen angles let light escape through the bottom: the stone goes dull. On my cuts, they are calculated to send it back to the eye.

II No window

A “window” is the washed-out, see-through area in the centre of a poorly cut stone. Calculated angles avoid it.

III No heavy pavilion

An oversized pavilion (the lower part) adds carats to the invoice, not brilliance. My proportions aim for beauty, not weight.

Stones I go and find myself

Most of my stones I go and find on site, in mines, rivers and quarries, alongside the miners and diggers, and, where it is allowed, digging myself. These journeys guarantee a known origin and field expertise that no certificate can replace: recognising good rough, judging its colour in daylight, anticipating what the cut will reveal.

Other stones are bought from suppliers chosen for their quality, then kept in stock to be recut at the workshop, refining their brilliance and lustre.

Colombia · Private mine

Emerald

I visited a private emerald mine with one of its co-owners and was able to dig in it myself, in the homeland of the world’s most sought-after emeralds.

Sri Lanka · Ratnapura

Sapphire, ruby, garnet…

At the local markets, in Ratnapura among others, but also at the bottom of a mine, where I went down to work alongside the local miners.

Australia · Rubyvale, Queensland

Sapphire

I worked on a newly opened sapphire claim in the Rubyvale area: excavator, trucks, bobcat, trommel… from digging the gravel to sorting the rough by hand.

Austria · Tyrol

Emerald

Several summers spent searching for the emeralds of the Tyrol, sleeping in the mountain hut alongside fellow Austrian, German and Swiss prospectors.

France · Alps and Auvergne

Rock crystal, amethyst, sapphire, spinel, peridot

France has its gems too: rock crystal in the mines of the Alps; amethyst, sapphire, spinel and peridot in Auvergne, in rivers, fields and quarries.

The bench pin

The cheville, or bench pin, is the wooden peg fixed to the jeweller's workbench. Against it the stone is fitted, the metal filed, the jewel shaped. The house bears its name.
