Antique 1ct Basaltic Sapphire and 1.50ct Diamond 18ct White Gold Cluster Earrings Circa 1930

1920 - 1940
For Sale by AC Silver
Description

A stunning, fine and impressive pair of antique 1.00 carat untreated Basaltic sapphire and 1.50 carat diamond, 18 carat white gold cluster earrings; part of our diverse collection of antique sapphire jewellery.

These stunning, fine and impressive antique sapphire earrings have been crafted in 18ct white gold.

The pierced decorated, cluster style earrings are each ornamented with a feature oval cut Basaltic sapphire, collet set in slight relief to the centre of the design.

The sapphires are each encircled with twelve transitional modern brilliant round cut diamonds, totalling 1.50cts, in a scalloped cluster border.

The white gold sapphire earrings, for pierced ears, secure to the reverse with a post and butterfly fastening.

These sapphire and diamond cluster earrings have been independently tested using state of the art technology (Niton XL2 Analyzer) and verified as 18 carat gold.

These impressive antique cluster earrings are supplied with an IDGL diamond and gemstone grading report card, in addition to a sapphire report card and certificate supplied by the Gemmological Certification Services, London*.

Such period examples in this very high diamond grade and set with untreated sapphires are becoming increasingly difficult to locate.

These antique oval sapphire and diamond earrings are a refined and timeless gift, perfect for anniversaries - especially the 5th or 45th - September birthdays or romantic occasions like Valentine's Day. They also make a memorable choice for brides or collectors of fine antique jewellery.

NOTE: * This documentation accredits the sapphires originating in Basaltic deposits and certifies that the gemstones show no indications of heating.

Images do not always reflect the true colour and brilliance of gemstones and diamonds. The video however provides a truer representation of the actual colour and showcases each stone in these sapphire and diamond earrings.

Condition

These impressive sapphire cluster earrings are excellent quality, set with stunning blue Basaltic sapphires displaying fine colour, brilliance and presence.

The high graded and well colour matched diamonds display a fine white colour and brilliance.

These sapphire and diamond cluster earrings are an excellent gauge of gold and are in excellent condition.

Reflections in photographs may detract from the true representation of this fine example of antique sapphire jewellery/estate jewelry.

Every single antique dealer on our platform is individually approved by our internal team. We verify their professional trade history, ethical standards, and photographic quality to ensure a secure, high-standard buying environment. Upon joining, every dealer agrees to a strict 9-point code of conduct. While issues can occasionally arise, our dealers typically resolve them swiftly and directly with the buyer. In fact, since our founding in 2002, Sellingantiques has only had to step in to help resolve an issue on roughly five occasions—a true testament to the quality of our dealers and their dedication to your happiness.
Our dealers are highly experienced in packing and shipping fragile, high-value antiques. Because you are in direct contact with the dealer, you will be able to easily go through all available shipping and insurance options together to ensure your item arrives safely.
Antiques are the ultimate green purchase. By choosing historical pieces over newly manufactured goods, you completely eliminate the carbon footprint of modern mass production while preserving exceptional, timeless craftsmanship.

Art Deco cluster earrings from the 1930s typically feature a central coloured gemstone, such as a sapphire, surrounded by a symmetrical border or halo of diamonds set in precious metals like white gold or platinum.

These pieces commonly utilise 18ct white gold, yellow gold, or platinum mountings to secure natural central gemstones alongside halo accent diamonds.

Authentic 1930s jewellery often displays period hallmarks, hand-cut gemstones, fine rubover or bezel settings, and characteristic geometric or floral cluster arrangements.

Classic cluster studs serve as versatile accent pieces that complement both formal eveningwear and tailored daytime attire due to their balanced proportions and refined aesthetic.

Clean gently using a soft-bristled brush with warm, mild soapy water, avoiding harsh chemicals, and store separately in a fabric-lined box to prevent surface scratches.
