TANZANITE
A blue purple night, with streaks of moonlight, will remind you of the lush Tanzanite.
Introduction
Tanzanite, a gemstone found exclusively in the Merelani Hills of Tanzania, is one of the most unique and sought-after stones in the world. Known for its striking blue-violet hue, tanzanite’s color can shift depending on the angle of light, displaying various shades of blue and purple. Its rare occurrence and stunning color make it a gemstone of exceptional beauty and value. Although it was only discovered in the 1960s, tanzanite quickly gained popularity and is now a beloved choice for fine jewelry.
Tanzanite’s strong pleochroism, which gives it different colors when viewed from different angles, is a key feature that adds to its mystique. Often compared to sapphire for its blue tones, tanzanite is believed to have metaphysical properties that enhance intuition, spirituality, and emotional healing. With a Mohs hardness of 6-7, it requires careful handling, but its exceptional color and rarity make it an exquisite choice for jewelry that stands out.
