While trends may come and go in the world of fashion, reinterpretation is a constant that design houses from Gucci to Louis Vuitton, Tiffany & Co, Van Cleef & Arpels, Bulgari and Cartier strive for. French design house Hermes is constantly reinventing itself by looking at the past. Its designers reinterpret items in its archives, and in the process create something new. One example is its jewellery division that pays homage to previous designs used throughout Hermes' history. A standout piece is called Collier de chien or dog collar, a bracelet in rose gold and brown diamonds. It harks back to Emile Herm?s' collection of hunting-dog collars that were inspired by the design of a Hermes belt. Pierre Hardy, art director of Hermes jewellery, explains the design is 'an allusion to the Hermes saddle tack, which is found on the Collier de chien bracelets in particular. I also emphasised rose gold and brown diamond paving. The relationship between the colour of the diamonds and the skin is stunning, magical. These pieces add a touch of sparkle. They highlight a specific part of the body.' Another interpretation is the Kelly bag made famous by Princess Grace of Monaco. Hermes has created a bracelet in brightly coloured crocodile with white gold and diamonds on its iconic clasp. The Kelly clasp can also be found on delicate bracelets of yellow or rose gold, and white gold set with diamonds. The house, known for its equestrian roots, has also reinterpreted the snaffle-bit design. In its bracelet called Nausicaa, the bracelet in white gold and diamonds has a smoked Clou d'H quartz, an exclusive cut created by Hardy. 'Coloured stones weren't part of the collections before,' he explains. 'They open up an exciting creative space in the world of Hermes jewellery. I came up with a new cut for these stones called Clou d'H. It adds radiance, while showing the exceptional quality and light of the stone without being flashy.' Meanwhile Montblanc, known for its writing instruments and watches, also has a jewellery collection that looks to its star emblem for inspiration. This year it releases its Montblanc cabochon, a re-interpretation of the classic stone cut. The result is a series of colourful pieces using an assortment of semi-precious and hard stones, each in the shape of the Montblanc star, reminiscent of the snowy peak on Europe's highest mountain. The stones chosen are prevalent in Eastern cultures and Montblanc has selected those that are recognised for their beneficial properties. The energy conveyed by these stones is said to carry benefits ranging from good health and inner strength to confidence, prosperity and success. The red rhodolite garnet and pink carnelian are synonymous with confidence, power and passion; the white and blue stones of milky quartz, aquamarine, iolite and amethyst are connected with feelings of contentment, humility and strength. The stones are set on chains, architectural bracelets, bangles, long earrings and delicate studs as well as rings. French brand Chaumet has a long history dating back to 1780 when Marie-Etienne Nitot founded the house. And Chaumet finds inspiration in its first muse, Empress Josephine. The latest additions to the Josephine Bijoux collection have their designs drawn from royalty with tiara rings in diamonds, rubellite and green tourmaline.
