Tanzanite - A Jewel Born from the Foothills of Kilimanjaro

🌍 Origin & History

Tanzanite is one of the rarest gemstones on Earth, found only in a small mining area near Mount Kilimanjaro in Tanzania. Discovered in 1967, Tanzanite quickly rose to global fame for its remarkable trichroism — the ability to show different colors when viewed from different angles.

Unlike many gemstones with global deposits, Tanzanite’s source is extremely limited, making it about 1,000 times rarer than diamonds.

At Mittal Gems, we are deeply passionate about sourcing Tanzanite that stays true to its natural allure — responsibly mined and carefully calibrated for modern jewelry creations.

🎨 Color Range & Characteristics

Tanzanite’s color is what truly sets it apart. It displays a breathtaking range:

• Violet-Blue: Most prized, especially under natural daylight
• Purplish-Blue: Under incandescent lighting
• Soft Lilac to Deep Indigo: Depending on the angle and stone size

Each Tanzanite piece selected at Mittal Gems undergoes careful grading to ensure optimal color vibrancy and consistency, ideal for fine jewelry production.

⛏️ Mining and Sources

All commercial Tanzanite comes from a mining area just 4 kilometers wide and 2 kilometers long in the Merelani Hills, near Arusha, Tanzania.

There are four main mining blocks (A, B, C, and D):

• Block C is the largest and most productive, supplying high-grade Tanzanite.
• Blocks D and A produce smaller quantities but sometimes exceptional quality stones.

Our sourcing partners prioritize ethical mining practices, ensuring that each gemstone we offer supports fair labor and sustainable mining communities.

🧠 Educational Insights

• Pleochroism: Strong — showing multiple colors from different angles, enhancing its visual magic.
• Formation: Tanzanite formed about 585 million years ago under extraordinary geological conditions, making it a true geological wonder.

📈 Interesting Facts
