FAQs

A trilogy ring, also known as a three-stone ring, traditionally symbolises the past, present, and future of a relationship, gaining significant popularity during the Victorian and Edwardian periods before evolving through the mid-20th century.

Mid-century rings frequently combined yellow gold bands with platinum or white gold illusion settings to enhance the brilliance of the diamonds and provide a secure mounting for coloured gemstones like sapphires.

Authentic pieces typically feature maker marks, metal purity stamps such as 18ct or platinum indicators, and traditional casting or hand-finished techniques characteristic of mid-20th-century craftsmanship.

A vintage sapphire and diamond ring serves as a versatile focal point that pairs effortlessly with contemporary minimalist jewellery or acts as an heirloom-inspired statement piece for daily wear.

To preserve the setting and stones, clean the ring gently with warm soapy water and a soft brush, avoiding harsh ultrasonic cleaners, and have the prongs checked periodically by a professional jeweller.
