Antique Art Deco 1.00ct Sapphire and 1.20ct Diamond Platinum Earrings Circa 1920

1900 - 1920
For Sale by AC Silver
Description

A fine and impressive pair of antique Art Deco 1.00 carat sapphire and 1.20 carat diamond, platinum and 14 carat white gold set earrings; part of our diverse antique sapphire earring collection.

These fine and impressive antique sapphire earrings have been crafted in platinum with 14ct white gold fastenings.

These stepped Art Deco style earrings are each ornamented with millegrain collet set two French cut sapphires, totalling 1ct.

Each sapphire is flanked with two Old European round cut diamonds, pavé set to square settings in a tiered linear formation.

The lower portion of each earring is embellished with a four-claw set square cut diamond, completing the design.

These Art Deco earrings, for non-pierced ears, secure to the reverse with a hallmarked 14ct white gold hinged latch fastening; this bears a hinged undulating grip to ensure a comfortable and firm fit of these delicate earrings in situ.

The reverse of the fastening bears the 14ct gold mark (14K) and the patent number (PAT 2423905); these earring settings have been independently tested using state of the art technology (Niton XL2 Analyzer) and verified as platinum.

The sapphire and diamond clip on earrings are supplied with an IDGL diamond and gemstone grading report card.

Art Deco diamond and sapphire earrings are a refined gift for milestone birthdays, anniversaries, engagements and wedding perfect as a 'something blue' for a bride. Embodying 1920s glamour, they appeal to Art Deco jewellery collectors and lovers of timeless elegance.

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 gemstone earrings are excellent quality, set with impressive sapphires displaying fine colour, brilliance and presence.

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

The earrings are an excellent gauge of gold and are in excellent condition, with clear hallmarks to the fastenings.

Reflections in photographs may detract from the true representation of these original Art Deco platinum diamond and sapphire earrings.

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 jewellery from the 1920s is defined by geometric shapes, bold colour contrasts, linear symmetry, and fine craftsmanship, frequently utilizing platinum and precious gemstones.

Craftsmen typically used platinum or white gold settings, hand-applied millegrain beaded edging, and precision-cut gemstones such as sapphires and diamonds set in geometric arrangements.

Authentic pieces feature period-appropriate gemstone cuts such as old European or calibre cuts, fine millegrain borders, period platinum hallmarks, and characteristic geometric structuring.

These geometric earrings serve as refined statement pieces, pairing seamlessly with contemporary evening wear, tailored suits, or modern minimalist outfits to add historical sophistication.

Store them separately in a soft-lined jewellery pouch, clean gently using warm water, mild soap, and a soft brush, and avoid exposure to harsh chemicals or ultrasonic cleaning.
