The most regal of colours, purple has long been associated with opulence and royalty – so a purple stone makes a lovely choice for a treasured piece of jewellery like your engagement ring! Whether you want a classic three-stone design or the dazzle of a halo ring, amethyst catches the light beautifully to reflect flashes of purple intensified by the glitter of diamonds. This distinctive colour is calming to wear and a very spiritual.
