Despite a ban, fourth-generation family firm Bonnet still offers timeless style to its aesthete clientele

RARE CRAFT: Christian Bonnet (L) and his apprentice Daniel work on pairs of tortoiseshell spectacle frames on November 19 in the company Maison Bonnet’s Sens workshop, south of Paris
PARIS: What did Yves Saint Laurent, Jackie Kennedy and the architect Le Corbusier have in common? Their eyewear, for one, as clients of the luxury French tortoiseshell artisan, Bonnet.

Four decades after the trade in tortoiseshell was banned under the 1973 CITES convention, the fourth-generation family firm sees itself as custodian of a rare craft, fashioning made-to-measure spectacles from stocks amassed before the ban. Bonnet describes its customers — among them Audrey Hepburn, Maria Callas or presidents Francois Mitterrand and Jacques Chirac — as “aesthetes” more concerned about timeless style than fashion.

Christian Bonnet, who learned the trade from his father and grandfather, holds the rank of “maitre d’art”, an honorific title granted by France’s culture ministry and currently held by just over 100 craftsmen nationwide.

Today jointly headed by Christian and his sons Franck and Steven, Bonnet turns out around 100 pairs of handmade tortoiseshell glasses per year for prices ranging from ¤3,500 to 30,000 ($4,500 to $38,600) “My father didn’t want me to go into the trade, because of the problem with tortoiseshell supply,” produced mainly from the shell of the endangered hawksbill turtle, Franck Bonnet told AFP. With 12 grammes of tortoiseshell needed for one pair of glasses, the firm says it uses around two to three kilos per year. Declared part of French national heritage in 2007, Bonnet will not say how much stock it holds, but the supply is finite.

“It is inconceivable that we would ever fish another turtle out of the ocean,” says the 41-year-old, himself a staunch environmentalist.

So he decided a few years ago, it was time to look to the future — and to a wider market. “For my father, my grandfather and great-grandfather before them, it was tortoiseshell, tortoiseshell, tortoiseshell only. I said to my father, ‘You are the last tortoiseshell craftsman, but you are also the last hand-made eyewear maker. If we could only use more readily available materials, maybe I can keep our craft alive?’ ” That is how from 2008 onwards, he introduced buffalo horn — lowering the average frame price to between ¤1,200 and 1,500, and acetate, for budgets between ¤850 and 1,150.

Tortoiseshell aside, the dozen workers at its Paris boutique and workshop in Sens, a few hours southeast of the capital, now produce some 700 pairs using new materials. The next step towards broadening what they offer is to come from customisation — allowing people to change the size and colour on standard models.

Bonnet was snared in controversy recently when a star journalist, Audrey Pulvar — then in a relationship with a Socialist minister —was outed for wearing a pair of their steeply-priced glasses. “It wasn’t ¤12,000, it wasn’t ¤15,000 or 18,000!”, as reported in the media, Bonnet told AFP. “Five thousand is more like it.” In other words, almost an entry-level model. “It’s true it is costly,” Bonnet said. “But we artisans are not millionaires, this kind of high craft is extremely time-consuming.”

Making glasses to measure means studying the face in minute detail.

“How high your ears are, the shape of your nose — all have an incidence on the tilt of the lenses, and therefore on how well you see,” he explained. And that is before all the different steps of shaping and polishing the frame.
