FAQs

Art Deco jewellery, spanning the 1920s and 1930s, is characterised by geometric symmetry, clean lines, stylised motifs, and a strong reliance on white metals such as platinum paired with diamonds.

Traditional materials from this era typically feature high-purity platinum settings combined with diamonds, often cut in old European, transitional, or baguette styles to maximise brilliance.

Authenticity is verified through hallmark stamps, metal testing, microscopic examination of setting techniques, and independent gemmological laboratory reports confirming stone weight and grading.

An antique ring can be worn alone as a striking statement piece or paired with minimalist contemporary wedding bands to highlight its historical craftsmanship.

Maintenance involves regular professional ultrasonic cleaning, checking claw integrity annually, and storing the piece individually in a lined jewellery box to prevent scratching.
