Navaratna () is a Sanskrit compound word meaning "nine gems" or "ratnas". Jewellery created in this style has important cultural significance in across many southern, and south-eastern Asian cultures as a symbol of wealth, status, and also as having other claimed talismanic benefits to health and wellbeing. The setting of the stones is believed to hold mystical powers, tied to astrology, mythology and intrinsically linked to the Indian religions of Hinduism, Jainism and Buddhism. The ancient origin of the significance behind the nine gems has proved impossible to trace but is inherently tied to mythological concepts around cosmology and astrology and the "Navagrahas", or "nine celestial gods".
