Art Deco jewellery, prominent during the 1920s and 1930s, is characterised by geometric precision, clean lines, stylised motifs, and a strong architectural influence.

Engagement rings from this era frequently combined platinum or white gold for settings to enhance diamond brilliance, paired with yellow gold bands, alongside hand-cut diamonds.

Authentic period rings often feature hand-cut diamonds such as old European or old mine cuts, hand-carved settings, specific makers marks, and signs of genuine age under magnification.

Vintage diamond rings offer a distinctive, individual aesthetic that contrasts sharply with modern mass-produced jewellery, making them a popular choice for sustainable and unique daily wear.

Antique rings require gentle cleaning with warm soapy water and a soft brush, avoiding harsh chemical ultrasonic cleaners, and professional inspection of the settings annually.
