Tanzanite is found only in Tanzania and shows blue, violet and burgundy from different angles.
In Vedic astrology, Tanzanite is linked with Saturn, the planet of discipline, hard work, career stability, patience and long-term success. The main gem of Saturn is Blue Sapphire (Neelam); Tanzanite is a gentler, more affordable stone that people choose to support the same planet.
Benefits of Wearing Tanzanite
- Supports spiritual growth and intuition
- Encourages calm
- An alternative for Saturn
- Strengthens the positive results of Saturn: discipline, hard work, career stability, patience and long-term success
Crystal and gemstone benefits are traditional beliefs and are not a substitute for medical or professional advice.
How to Wear Tanzanite
- Weight: there is no strict rule; a stone of 5 to 7 carats in a ring, or any comfortable size in a pendant or bracelet, is common.
- Metal and finger: set it in silver or panchdhatu and wear it on the middle finger of your working hand.
- Day and time: wear it for the first time on a Saturday, in the evening, preferably during the Shukla Paksha (waxing Moon).
- Purify: dip the ring or pendant in raw milk mixed with Ganga jal (or clean water) for a few minutes, then rinse it.
- Energise: light a lamp, face east and chant the Saturn mantra 108 times: Om Praam Preem Praum Sah Shanaischaraya Namah.
Saturn stones can act quickly. Many astrologers suggest a trial: keep the stone under your pillow or wear it for three days and notice how you feel before wearing it regularly.
Who Should Wear Tanzanite?
- People whose Moon sign or Ascendant is Capricorn and Aquarius, ruled by Saturn.
- Anyone running the Saturn Mahadasha or Antardasha, when Saturn is a helpful planet in the chart.
- People who want more of Saturn's qualities: discipline, hard work, career stability, patience and long-term success.
Use care when combining stones: stones of Mercury, Venus, Saturn, Rahu and Ketu work well together, but are usually not combined with stones of the Sun, Moon or Mars.
Care and Cleaning
Tanzanite has medium hardness (about 6.5 on the Mohs scale). It is fine for rings worn with care. Clean it with lukewarm water, mild soap and a soft brush, and take it off for heavy work, cleaning and swimming. Many people also re-energise their stone once a month by placing it in moonlight or chanting the planet's mantra.
Tips for Buying Tanzanite
- Choose a natural, untreated stone; heated, dyed, glass-filled or synthetic stones are not considered astrologically effective.
- Ask for a lab certificate from a recognised gem laboratory.
- Good colour, clarity and a clean cut matter more than size.
- Buy from a trusted seller who explains the origin and any treatment of the stone.
