Pierre Sterlé was born in 1905 into a family of high-ranking financial officials. At the death of his father during the First World War, he was left under the tutelage of an uncle, an established jeweller with premises in Paris, in rue de Castiglione. This initial exposure to the world of jewellery was to prove of paramount importance for the choice of his career. In 1934, after having worked for several Parisian jewellers, he set up his own business in rue Saint Anne from where he moved twice, firstly to rue de Moulins and then to 45, avenue de l'Opéra before closing some thirty years later. In spite of the loyalty of an international clientele, financial difficulties forced him in 1961 to sell numerous designs from his inventory to Chaumet. In 1976 Chaumet took him up in the capacity of creative advisor.
The jewels of Pierre Sterlé are distinctive in design and superbly crafted. His diamond creations are immediately recognisable, featuring dramatic overlapping and twisted motifs such as ribbons, feathers and leaves, rendered in the most elegant and wearable designs. His remarkable talent and audacious creativeness was acknowledged three years in succession with the prestigious De Beers' Diamond International Award.  Pierre Sterlé was fascinated by the decorative potential offered by gold. He worked and manipulated the metal to reproduce the different textures of fabric and textiles: tassels, fringes, cords, mesh, basket weave. Semiprecious and unusual stones often featured in his audacious creations, combined with gold and diamonds. Nature offered an inexhaustible source of inspiration: flowers, leaves, animals and especially birds were recurrent motifs in his production. All Sterlé's jewels, whether lavishly set with diamonds or beautifully crafted in gold, share the same characteristic: that of being instantly recognised as the work of a genius.
