Style
Art Deco - Art Deco is an eclectic artistic and design style which had its origins in Paris in the first decades of the 20th century. The style originated in the 1920s and continued to be employed until after World War II. The term "art deco" first saw wide use after an exhibition in 1966, referring to the 1925 Exposition Internationale des Arts Décoratifs et Industriels Modernes that was the culmination of high-end style modern in Paris. Led by the best designers in the decorative arts such as fashion, and interior design, Art Deco affected all areas of design throughout the 1920s and 1930s, including architecture and industrial design, as well as the visual arts such as painting, the graphic arts and film. At the time, this style was seen as elegant, glamorous, functional and modern.

Technique
Enamelling is an old and widely-adopted technology. The ancient Egyptians applied enamels to pottery and stone objects. The ancient Greeks, Celts, Russians, and Chinese also used enameling processes on metal objects. Enamel is the colorful result of fusing powdered glass to a substrate by firing, usually between 750 and 850 degrees Celsius. The powder melts and flows and hardens to a smooth, durable vitreous coating on metal, glass or ceramic. According to some sources, the word enamel comes from the High German word smelzan (to smelt) via the Old French esmail. Used as a noun, "an enamel" is a usually small decorative object, coated with enamel coating, such as a champlevé or a cloisonné (different techniques).

Furthermore, we present our antique and vintage jewellery in its authentic state, refraining from removing scratches or applying rhodium plating to white gold items. Our priority is to preserve the genuine allure and history of each piece. However, as the new owner, you have the option to take it to a local goldsmith for a cosmetic refresh, should you choose.
