Queen Camilla’s ‘geometric’ engagement ring contrasts Diana’s ‘classic’ and ‘opulent’ ring

Queen Camilla wears a five-carat emerald-cut diamond ring with baguette side stones, and it is extremely popular with royal fans. The ring used to belong to King Charles’ grandmother, the Queen Mother, who was seen wearing it in the 1980s. The Queen’s Art Deco-inspired ring combines timeless elegance with modern style, similar to Kate Middleton’s.

Expert Kathryn Money, from Brilliant Earth, previously said the engagement ring would have cost around £78,000. While this may have been the original cost of the ring, its historic and sentimental value render it priceless.

Charlotte White, head of design at Europe’s largest online diamond jeweller, 77 Diamonds, previously spoke to Express.co.uk about Camilla’s ring and its sentimental value.

The expert said: “When Charles got down on one knee and asked Camilla to marry him in 2005, he did so with a clean, contemporary, magnificent diamond engagement ring.

“It is more reminiscent of the geometric bold lines favoured by today’s young fashionistas, in contrast to, for example, the classic and opulent oval and diamond halo of Princess Diana’s sapphire ring.

“It was passed down to him from the Queen Mother, who was first pictured wearing it in the 1980s.

“Although the royal household has never divulged its date of creation or why it was commissioned, they have called it a family heirloom, implying a certain depth of history.

“Some speculate that the ring was in fact made to celebrate Queen Elizabeth II’s birth in 1926.”

The royal couple announced their plans to marry in February 2005, and they tied the knot on April 9. This means the couple have been married for just shy of 21 years.

The expert added: “The ring itself is an Art Deco piece and features five carats of emerald-cut diamonds.

“Emerald cut diamonds are a rectangular shape with cropped corners. They also have a step cut, which comprises facets arranged as parallel lines on all four sides.

“This creates what diamond industry insiders call a hall of mirrors effect as the light ripples over the glittering stone.”
