FAQs

Art Deco jewellery is characterised by geometric precision, stylised motifs, symmetry, and a strong influence from modern industrial architecture and machinery of the early 20th century.

Platinum became the dominant metal for high-end jewellery during this period due to its strength and ability to hold fine millegrain detailing, frequently paired with diamonds hand-cut in old European or transitional styles.

Authentic pieces typically exhibit hand-cut gemstones with distinctive facets, hand-crafted metalwork such as openwork filigree or millegrain edges, and signs of genuine age-related wear on the setting.

Vintage rings can be worn as standalone statement pieces or paired alongside minimalist modern bands to create a balanced contrast between historical craftsmanship and contemporary aesthetics.

Preservation requires regular professional inspection of the prongs and setting integrity, gentle cleaning using warm soapy water and a soft brush, and separate storage to prevent scratching.
