Art Deco

The name given to a artistic movement that was derived from the 1925 Exposition Internationale des Arts Décoratifs et Industriels Modernes which took place in Paris, France. This incredible exhibition showcased the new modern style that had already started to win favour in stylish European cities.

Coined the 'Art Deco' or 'Deco' period shortened from the French Arts Décoratifs, the era spanned the 1920s and 1930s. The style included geometric patterns, symmetrical motifs and parallel lines. These decorative symbols would go on to influence a wide variety of visual arts including architecture, paintings, sculpture, fashion and of course jewellery.

Jewellery items made during the Art Deco period stand out due to the quality of craftsmanship, the unique design, the pairing of unusal gemstones and the use of platinum.

Baguette cut

A long narrow rectangular shaped gemstone cut with straight parallel facets in a step pattern. The word baguette comes from the French translating to 'rod'. The often slender and tapering shapes of these reflective cuts lend themselves well as highlights or secondary gemstones to a centrepiece. 

Due to their angular shape the baguette cut is most often seen in Art Deco jewellery.

Byzantine Empire

The Byzantine Empire, also known in history as Byzantium or even the East Roman Empire was founded by Constantine I circa 330AD. The name Byzantine is said to have derived from the original name of the capital city Byzantium which was renamed Constantinople. Over the centuries this empire included a vast land mass which at times included modern day Italy, Greece, the Balkans, Turkey and Northern Africa. Although influenced by the traditions of the territories encompassed within the kingdom, the conversion of Emperor Constantine I to Christianity made any other form of worship void. 

Spanning from 330AD to 1453AD, at the height of its power Byzantium is said to have housed the richest, most lavish and most important christian city in the world, its capital Constantinople. 

Jewellery from this era is often found in high carat yellow gold and silver, granulation and wirework in relief are used as decoration, whilst christian motifs such as crosses, saints and other heavenly symbols are staples in the jewels found from this era.

Parisian jewellery firm founded by Etienne Nitot in the 1780s. The first recorded location for this firm was a small jewellery store in the Rue St Honoré. Perhaps the greatest achievement of the firm was gaining Napoleon I as a client, which supposedly happened after Nitot rescued the Emperor from an accident involving his carriage. In 1802 Chaumet became the French Emperor's official jeweller and went on to create bespoke pieces for both of the Emperor's weddings, the Coronation Crown and even the hilt of his sword.

The business continued to be run by Nitot family until the fall of the Empire in 1815 when it was purchased by Jean Baptiste Fossin. The Fossin family continued in the tradition of creating fine jewels for the elite in society. Amongst their important clientele included Louis-Phillippe, King of France and Princess Mathilde Bonaparte. With such a prestigious list of clients, Chaumet was expanded abroad and the Fossin's opened a boutique in London entrusted to Jean-Valentin Morel and his son Prosper Morel.

Soon their wares were celebrated by Queen Victoria and they recieved the much coveted Royal Warrant. The control of the firm continued in the hands of the Morel family. In 1889 Chaumet fell into the hands of Prosper's son-in-law Joseph Chaumet and stayed in the Chaumet family until it was sold in 1987 by Investcorp and eventually LVMH in 1999.

Through the Art Deco period Chaumet were recognised as trendsetters of the new style, showcasing at the famed 1925 Exposition des Arts Décoratifs in Paris. Their use of quality gemstones and unusual designs make them a formidable and historic jewellery house.
