Everyday jewellery just got better with Ernest Jones' Alexandrite Collection. Made with one of the rarest gemstones in the world, all our Created Alexandrite pieces are carefully selected and paired with diamonds that compliment the vibrant colours it emits. Alexandrite is a unique gemstone, as it can give off a range of colours, depending on the light, and makes a brilliant centerpiece for rings, earrings and necklaces. It is also one of the more durable gemstones which makes it ideal for everyday wear, but also an ideal addition to any jewellery lover's collection, and when given as a gift, makes quite the impression.
