Antique 1.00ct Diamond and Platinum Necklace Circa 1920

1900 - 1920
For Sale by AC Silver
Description

A stunning, fine and impressive antique 1.00 carat diamond and platinum drop pendant necklace; part of our 1920s diamond jewellery collection.

This stunning, fine and impressive antique diamond drop pendant necklace has been crafted in platinum.

The pierced decorated, pear-shaped drop of the pendant is ornamented with a feature collet set 0.14ct Old European round cut diamond, displayed within a circular fenestrated rosette design.

The feature diamond is set to the terminal of the articulated drop, embellished further with a trefoil shaped foliate design embellished with three pavé set eight cut diamonds.

The diamond drop pendant suspends from two further circular settings, reflecting the aforementioned rosette design, conjoined with collared wirework links.

The necklace bears eight further rosette settings, each accented with a graduating sized Old European round cut diamond to the centre, completing the anterior design.

The pendant suspends from a platinum chain via two ring loops to the upper borders of the design; the chain secures with a conventional spring-loaded bolt ring fastening.

This 1920s necklace has been independently tested using state of the art technology (Niton XL2 Analyzer) and verified as platinum.

This antique diamond necklace is supplied with an IDGL diamond grading report certificate for the feature stone, in addition to an IDGL diamond grading report card for the supporting stones.

This 1920s diamond drop pendant necklace is an elegant choice for weddings, anniversaries, or milestone birthdays, equally suited to bridal wear or a romantic gesture. Its refined vintage design lends itself to evening occasions and enduring heirloom appeal.

Condition

This impressive antique 1920's diamond drop necklace is excellent quality, set with high colour graded feature diamonds displaying a fine white colour, brilliance and presence.

The impressive supporting diamonds display a fine white colour and brilliance.

The pendant is an excellent gauge of platinum and is in excellent condition.

Reflections in photographs may detract from the true representation of this fine example of diamond jewellery.

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 characterised by geometric patterns, fine filigree metalwork, platinum settings, and the prominent use of diamonds and contrasting gemstones.

Platinum was favoured during this era for its strength and pale tone, which allowed jewellers to create lightweight, lace-like filigree settings that held diamonds securely.

Authentic pieces usually feature period platinum purity hallmarks, hand-carved filigree detailing, milgrain edging, and period cuts such as old European or single-cut diamonds.

An antique drop necklace complements evening dresses with plunging or open necklines, or provides detail when positioned over a plain silk blouse.

Clean using warm water, neutral detergent, and a soft brush, ensuring harsh chemical cleaners are avoided, and store the item in a fabric-lined box to prevent scratching.
