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.

Style specifics
Abstract motives and geometrical forms are quite typical for the Art Deco period.
Period
ca. 1930
Material
platinum (touchstone tested)
Diamonds
77 old mine brilliant cut diamonds with an estimated weight of ± 6.90ct colour and clarity F/H, vs/si
All diamond weights, color grades and clarity are approximate since stones are not removed from their mounts to preserve the integrity of the setting.
All diamonds we offer are screened by the I.J.G.C. for whether they are natural or synthetic, and all diamonds in this jewel are 100% guaranteed to be natural.
Precious stones
Four sapphires (lab produced) (also called verneuil sapphire). The fact that these stones are lab produced 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.
Hallmarks
No trace.

- Antique and vintage jewellery often undergoes thoughtful refurbishment, remodelling, or repairs to enhance its longevity and wearability. Such pieces frequently bear marks of this tender care. 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.
