Blue sapphire in Vedic astrology

In jyotish, blue sapphire (neelam) is the gemstone of Shani, the planet Saturn, and is considered one of the most powerful gemstones. It is traditionally set in silver, gold or panchdhatu, worn on the middle finger, and first put on on a Saturday. Neelam is traditionally worn only on an astrologer's advice, and many first wear it on trial for a few days, so please consult your astrologer before wearing it.
