Description

A stunning, fine and impressive antique 2.48 carat diamond and platinum halo pendant; part of our expansive 1920s jewellery collection.

This stunning antique diamond pendant has been crafted in platinum.

The pierced decorated, circular-shaped frame displays a feature suspended claw set 1.70ct Old European cut diamond.

The surrounding halo-style millegrain scalloped decorated frame is ornamented with twenty pavé set diamonds, in a combination of Old European and eight cuts.

The scalloped setting suspends from a collet set Old European round cut diamond, completing the design.

The reverse of the setting bears an additional arched frame to support the articulating feature diamond; this indicates the high quality of the piece.

The pendant suspends from a 16" chain via two ring loops to the upper border and secures with a conventional spring-loaded lobster clasp fastening to the reverse.

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

The pendant is supplied with an IDGL diamond grading certificate for the feature diamond, in addition to an IDGL diamond grading report card for the supporting stones.

This 1920s diamond halo pendant in platinum is a timeless piece of jewellery, highly sought after by collectors and connoisseurs alike. It makes an exquisite gift for weddings, anniversaries or birthdays, with its enduring brilliance and refined design ensuring it will be cherished for generations. Perfect for evening occasions, black-tie events or adding vintage sophistication to a bridal ensemble.

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 pendants from the 1920s typically feature geometric precision, millegrain edging, and the extensive use of platinum to accentuate white diamonds.

Platinum was favoured for its strength and neutral tone, allowing jewelers to create delicate, lace-like settings without compromising structural integrity or stone colour.

Authentic pieces feature hand-cut diamonds such as Old European cuts, fine millegrain detailing around borders, and period-appropriate hallmarks on the platinum mountings.

An antique diamond pendant can be styled alongside simple necklines, tailored suits, or layered with delicate contemporary chains for a subtle contrast.

Clean the piece gently using warm water, mild soap, and a soft-bristled brush, and ensure the settings are periodically checked by a professional jeweller.
