Edwardian, 18ct Gold, Platinum, Natural Colour-Change Sapphire and Diamond Ring

Edwardian, colour-change sapphire and diamond cluster ring, circa 1910. An extraordinary gem sits at the centre of this beautiful sapphire and diamond ring. A sapphire is formed from a mineral called corundum, they come in a wide range of colours; blue, pink, green, yellow, orange, purple, colourless and black. However, in rare circumstances, the corundum can develop chameleon-like qualities; change colour. A ‘colour-change’ sapphire can change colour when exposed to different light sources. A true wonder of nature, these gems are as beautiful as they are unique. This colour-change sapphire is surrounded by single-cut diamonds, with a slightly larger diamond on each point. The gallery (underneath section) is extremely beautiful, the intricately pierced gold work demonstrates the true quality and overall attention to detail given to this ring. It’s a very special ring and would make a perfect engagement ring.
