Description

A stunning, fine and impressive antique 1.28 carat diamond and platinum pendant - boxed; part of our diverse 1920s diamond jewellery collection.

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

The 1920s necklace features a stunning claw set 1.16ct Old European cut diamond.

The feature diamond terminates from a plain linear drop, suspended from a millegrain decorated collet style setting, which displays a second impressive 0.12ct Old European round cut diamond.

The diamond pendant is suspended from a platinum chain via two integrated ring loops to the upper border.

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

This impressive pendant 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 stone.

The pendant is fitted to the original hinged leatherette presentation box, with a velvet and satin lined interior, securing with a push fit catch.

This boxed 1.28 carat diamond drop necklace has refined brilliance and is a memorable gift for landmark anniversaries, milestone birthdays or elegant evening occasions.

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

The stunning 1920s necklace is excellent quality, set with stunning diamonds displaying a fine white colour, brilliance and presence.

This antique diamond drop necklace is an excellent gauge of platinum and is in excellent condition.

Jewellery from this era frequently features platinum settings paired with old-cut diamonds, often characterised by geometric lines, delicate pierced work, and milgrain detailing.

Platinum became the metal of choice during the early twentieth century due to its strength, allowing for finer wirework and secure claw settings that maximised light transmission through diamonds.

Authentic pieces typically exhibit hand-cut gemstones with distinctive old-cut facets, handcrafted platinum settings with natural patina, and period-appropriate clasp mechanisms.

This piece works well when layered with contemporary fine chains or worn alone as a focal point against minimalist necklines to highlight its historical craftsmanship.

Store the item individually in a lined jewellery box to prevent scratching, and clean periodically using warm soapy water and a soft brush, avoiding harsh chemical ultrasonic cleaners.
