The colour of enchanted forests, lush valleys and the new shoots of spring, emeralds are associated with Mother Nature, rebirth and renewal, making them the perfect birthstone for the month of May. Emeralds are known for their natural patterns of internal inclusions, known as ‘jardins’ which make each one entirely unique. Jessica McCormack offers an irresistible array of lush emeralds in all shapes and sizes. Our emerald heart-shaped Button Back necklace wraps the neck with 45 mouth-watering heart-shaped emeralds: enough to make Cleopatra green with envy.
