August's birthstone peridot is surrounded by two diamond-set loops and set in 18ct yellow gold. Adjustable 18inch chain included. Thought to cleanse the mind and promote peace and compassion, peridot’s yellow-toned green colour is reminiscent of a well-groomed lawn in summer, and Ancient Egyptians aptly referred to it as the ’gem of the sun’ (peridot is approximately 0.20ct, diamond is 0.26ct)
