Line Vautrin was born in Paris, France, in 1913 to a family of metalworkers. Mastering the trade at an early age, Vautrin left school at age 15 to pursue metal craft full time. In 1937, she secured a booth at the International Exhibition in Paris, and her jewellery began to receive widespread recognition. She quickly opened a boutique in the heart of Paris to offer her creations to a select clientele and famous decorators.

Her works are are marked by superior craftsmanship and close attention to detail. Many of her pieces are engraved or cast with witty rebuses or have intellectual artistic themes that warrant careful examination. With her innovative and personal pieces, Vautrin attracted important clients such as Ingrid Bergman, Yves Saint Laurent, and Brigitte Bardot. In 1962, she closed her boutique and opened a metalworking school with her daughter.
