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 Decoratifs et Industriels Modernes that was the culmination of high-end style moderne 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. Style specifics: Abstract motives and geometrical forms are quite typical for the Art Deco period. Art Deco moved away from the soft pastels and organic forms of its style predecessor, Art Nouveau, and embraced influences from many different styles and movements of the early 20th century, including Neoclassical, Constructivism, Cubism, Modernism, and Futurism. Its popularity peaked in Europe during the Roaring Twenties and continued strongly in the United States through the 1930s. Although many design movements have political or philosophical roots or intentions, Art Deco was purely decorative. Period: ca. 1920 Material: Two tones of precious metal, the main part being 18K yellow gold and the white parts are either white gold or platinum. Extra information: Betrothal rings were used during Roman times, but werent generally revived in the Western world until the 13th century. The first well-documented use of a diamond ring to signify engagement was by the Archduke Maximilian of Austria in imperial court of Vienna in 1477, upon his betrothal to Mary of Burgundy. Before the 20th century, other types of betrothal gifts were common. Before the end of the 19th century, the bride-to-be frequently received a sewing thimble rather than a engagement ring. This practice was particularly common among religious groups that shunned jewelry. Engagement rings didnt become standard in the West until the end of the 19th century, and diamond rings didnt become common until the 1930s. Now, 80% of the women are offered a diamond ring to signify engagement. (from: Wikipedia) Diamonds: Six rose cut diamonds. We do not have the weight of the diamonds which is normal in our trade when it comes to rose cuts. Note: All diamond weights, color grades and clarity are approximate since the stones were not removed from their mounts to preserve the integrity of the setting. Precious stones: Four triangle cut and one emerald cut sapphire . We did not check if the sapphires are lab produced or not as this information has no influence on the value of this jewel. Natural sapphires and lab produced sapphires were both used in this era, rather more for their effect than for their intrinsic value. Birthstones: Diamond is the birthstone (or month stone) for April and sapphire for September.
