Born in Paris in 1975, Ms. Sivrière grew up between the mountain resorts of Megève and Chamonix, in southeastern France. She was drawn to jewelry at a young age, after meeting a friend of her father’s who worked in the diamond trade. “I was mesmerized by the beauty and reflection of this stone,” she wrote.
Ms. Sivrière enrolled at a jewelry and gold smithing school in Paris, since renamed the Haute École de Joaillerie, where she studied various jewelry-making crafts. After graduation, she worked freelance for a jewelry company on Place Vendôme in Paris. Then, in 2002, she joined Piaget as a jewelry designer, attracted, she said, by the opportunity to help the brand, known as a traditional watchmaker, strengthen its jewelry business.
“It was a different time for the brand and the industry; fine jewelry wasn’t as big as today,” she wrote.
In 2011, Ms. Sivrière was named director of jewelry creations, and in 2016, she began overseeing watches, reflecting Piaget’s newfound interest in ensuring that its watch and jewelry designs were in harmony.
“When I was asked to work on watches, it was a challenge because they had two different vocabularies,” she said. “Today, it makes perfect sense. I can play with both.”
On her wrist, Ms. Sivrière regularly wears what many watch lovers would consider the purest distillation of the brand’s watchmaking expertise, the Altiplano Ultimate Automatic, “the essence of Piaget’s artistry in a watch,” she wrote.
