Antique 1.30ct Basaltic Sapphire and 2.10ct Diamond, 18ct White Gold Cluster Earrings Circa 1930

1920 - 1940
For Sale by AC Silver
Description

A stunning, fine and impressive pair of antique 1.30 carat untreated Basaltic sapphire and 2.10 carat diamond, 18 carat white gold and platinum set cluster earrings; part of our diverse gemstone jewellery collections.

These stunning, fine and impressive sapphire earrings have been crafted in 18ct white gold with a platinum setting.

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

The sapphires are each encircled by eight Old European round cut diamonds, totalling 2.10cts.

The antique earrings, for pierced ears, secure to the reverse with a post and butterfly style 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 and platinum.

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 sapphire cluster stud earrings in white gold are a refined and versatile gift, ideal for September birthdays, anniversaries, graduations or special occasions. Their timeless design offers enduring elegance for everyday luxury or meaningful milestones.

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.

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.

The sapphire stud earrings are an excellent gauge of gold and platinum, 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 prominent central coloured gemstone, such as an oval sapphire, framed by a halo of brilliant or transitional-cut diamonds set in platinum or white gold.

Jewellers of this era commonly utilised 18ct white gold or platinum to enhance the brilliance of surrounding diamonds and complement the deep tone of sapphires.

Authentic period pieces display fine millegrain border details, hand-set gemstones, and period-specific hallmarks on the posts or scroll backs.

These stud earrings function as understated focal points for formal evening wear or as tailored accents alongside modern fine jewellery.

Clean them using warm water, mild detergent, and a soft brush, ensuring they are stored separately to prevent metal friction and stone abrasion.
