"When platinum was introduced to jewellers at the turn of the 20th century, it took the industry by storm. Platinum was strong and kept its shape, even when you cut it into thin strips (unlike gold, which is much softer) and didn’t tarnish like silver. In fact, the metal shone so brightly that jewellers started to tone this down to let the stones stand out, and the stippled effect they created around the edges of the settings to achieve this was called ‘millegrain’, meaning ‘thousand grains’. This ring, with its delicate openwork construction, shows the technical feats that jewellers were able to perform with this amazing new metal. Set with a mix of early twentieth-century circular-cut diamonds and accented with baguette-cut sapphires, this beautiful ring, with its intricate openwork construction, shows off the innovations of this classic era of jewellery history, in a design that still translates beautifully to the modern day."
