Tanzanite is sometimes called the “workaholic’s stone”. This is because it helps you slow down and take it easy. This in turn, brings success in more areas of life and it relieves stress and enhances composure, poise, and harmony.
Physically it is beneficial for stress related illnesses and high blood pressure in particular.
Tanzanite has its own intense violet/blue colour, but can also be found in paler colours or bright Sapphire blue. Read the Metaphysical Properties of the colour of your particular stone.
