FAQs

Mid-century sapphire cluster rings, particularly those produced during the 1960s, often feature prominent central coloured gemstones framed by round brilliant and geometric accent diamonds set in white precious metals.

These pieces generally feature natural Sri Lankan sapphires prized for their vivid blue hue, paired with diamonds mounted in platinum or gold settings.

Authentic rings from this era feature precise metal hallmarks, hand-finished claw settings, and characteristic side accents such as baguette-cut diamonds flanking the main cluster.

A large sapphire cluster ring serves as an understated statement piece, ideal for pairing with formal evening wear or tailored modern tailoring to highlight the central gemstone.

Clean the ring gently using warm water with mild soap and a soft brush, avoiding harsh chemicals, and store it in a fabric-lined box to prevent stones from scratching other items.
