The finely-crafted pierced decorated, rectangular rounded design setting is ornamented with a feature 2.50ct octagonal cut Colombian emerald, collet set to the centre.

The emerald is encompassed with twenty-six pavé set diamonds, in a combination of Old European and eight cuts, graduating in size depending on location.

The pierced decorated, elevated ring shoulders integrate with the main setting with a cuff design and blend seamlessly with the plain ring shank.

The ring is hallmarked to the outer surface of the shank with the French import platinum mark (masked man) and has been independently tested using state of the art technology (Niton XL2 Analyzer) and verified as platinum.

Its exceptional gemstone, historic provenance and heirloom-quality craftsmanship make it a piece to be treasured for a lifetime and passed down through generations as a lasting symbol of elegance and enduring significance.

'Rather than regarding inclusions in coloured stones as harmful, in small sizes and numbers that do not in any way detract from their beauty, they should be regarded as adding to desirability, for they provide identifying characteristics.'

NOTE: * This documentation accredits the emerald originating in Colombia and certifies that the gemstone shows moderate amount of oil in fissures.

This Art Deco dress ring dates from the 1920s and is manufactured from platinum. The centre holds a green octagonal cut Colombian emerald set in a bezel mounting, surrounded by an elongated geometric pierced frame decorated with pavé set diamonds in a combination of Old European and eight cuts. The silver-coloured metal features milgrain detailing, elevated ring shoulders with a cuff design, and a plain ring shank bearing a French import platinum hallmark on the outer surface. Buyers wear this piece upon the finger as a statement accessory for formal occasions, milestone celebrations, or as an alternative engagement ring. It is styled for daily wear when paired with evening attire or vintage-inspired ensembles, adding a sophisticated geometric accent to the hand. The composition combines precious gemstones with fine metalwork characteristic of the period, creating a traditional heirloom item suitable for contemporary jewellery collections.

Art Deco emerald rings typically feature geometric outlines, platinum mountings, and contrasting diamond surrounds designed to highlight the central gemstone.

Rings from this era were primarily crafted in platinum or white gold, incorporating precious gemstones such as Colombian emeralds and diamonds secured with hand-applied milgrain detailing.

Authentic pieces often feature hand-cut gemstones, milgrain edging along bezel settings, geometric pierced platinum lattice work, and hallmarks consistent with the early 20th century.

An antique emerald statement ring pairs effectively with clean-lined contemporary eveningwear or neutral tailored suits, allowing the green gemstone and platinum metalwork to serve as a focal point.

Emeralds contain natural inclusions and require gentle cleaning using mild soapy water and a soft brush, avoiding ultrasonic cleaners, steam, or harsh chemicals.
