Style
Art Deco - Art Deco 是一项起源于20世纪初巴黎的折衷艺术与设计风格。该风格起源于1920年代，直至二战后仍被广泛应用。术语“art deco”在1966年的一次展览后开始广泛使用，指向巴黎在1925年举办的Éxposition Internationale des Arts Décoratifs et Industriels Modernes 的高端现代风格巅峰。由装饰艺术领域的顶尖设计师（如时装、室内设计）领衔，Art Deco 影响了整个1920年代和1930年代的设计各领域，包括建筑、工业设计，以及绘画、平面设计和电影等视觉艺术。当时这一风格被视为优雅、迷人、功能性与现代感的象征。参考：Art Deco

Eight senailles . A senaille is a simplified rose cut diamond, a small diamond chip with perhaps a few polished facets. We do not have the weight of these diamonds which is normal in our trade when it comes to senailles.
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
Two natural untreated rubies with an estimated weight of ± 0.34ct
Treatment: most probably not treated (no indications of treatments found)
Two salt water pearls

All color stone weights are approximate since stones are not removed from their mounts to preserve the integrity of the setting.
It is a very common practice to treat gemstones to intensify their clarity or colour. The item in question has not been tested in this regard.

- 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.
