🌄 The Discovery of Tanzanite
Tanzanite was discovered in 1967 in the foothills of Mount Kilimanjaro in northern Tanzania. A local Maasai tribesman reportedly found beautiful blue crystals on the ground after a lightning-induced bushfire cleared the land.
The gemstone was later introduced to the global market by the luxury jewelry brand Tiffany & Co., which named it “tanzanite” after its country of origin, Tanzania.
This branding helped propel the gem to international fame. Today, tanzanite remains one of the most coveted colored gemstones in the world. 🌍💙
🔬 What Is Tanzanite?
Tanzanite is the blue to violet variety of the mineral zoisite. While zoisite naturally occurs in various colors (green, brown, yellow), the blue-violet form is exceptionally rare and valuable.
Chemical Composition:
- Calcium aluminum silicate hydroxide
- Formula: Ca₂Al₃(SiO₄)(Si₂O₇)O(OH)
Crystal System:
- Orthorhombic
Hardness:
- 6 to 7 on the Mohs scale
This makes tanzanite suitable for jewelry but requiring some care compared to harder gemstones like sapphires or diamonds.
🌈 The Magic of Pleochroism
One of tanzanite’s most fascinating features is pleochroism — the ability to show different colors when viewed from different angles.
Tanzanite can display:
- Deep blue 💙
- Violet 💜
- Burgundy or reddish tones ❤️
When properly cut, lapidaries orient the stone to emphasize its most desirable blue-violet hues.
🔥 Heat Treatment and Color Enhancement
Most tanzanite on the market is heat-treated to enhance its color. Natural rough often appears brownish or yellowish. Gentle heating (typically around 500–600°C) transforms it into the vivid blue-violet color we love.
This treatment:
- Is permanent
- Is widely accepted in the gemstone industry
- Does not reduce value when properly disclosed
Untreated blue tanzanite is extremely rare and highly valuable.
📍 Where Is Tanzanite Found?
Tanzanite is mined exclusively in a small mining area near:
- Mount Kilimanjaro
- The Merelani Hills in northern Tanzania
This mining region is only about 4 kilometers long and 2 kilometers wide. Because it is a single-source gemstone, its rarity increases every year as mines become depleted.
💎 Tanzanite Meaning and Symbolism
Tanzanite is associated with:
- Spiritual awakening 🌌
- Intuition and psychic ability 🔮
- Transformation and new beginnings 🌱
- Calmness and emotional balance 💙
It is believed to connect the heart and mind, encouraging compassionate communication and inner peace.
♐ Tanzanite as a Birthstone
In 2002, tanzanite was added as an official December birthstone alongside turquoise and zircon.
It is often linked to:
- Sagittarius ♐
- Capricorn ♑
Because of its relatively recent addition, tanzanite is one of the youngest birthstones in modern gemology.
💍 Tanzanite in Jewelry
Tanzanite is widely used in:
- Rings 💍
- Earrings ✨
- Pendants 💎
- Bracelets
- High-end statement necklaces
Its vibrant color pairs beautifully with:
- White gold 🤍
- Yellow gold 💛
- Platinum
Because of its moderate hardness, protective settings are recommended for rings intended for daily wear.
💰 Tanzanite Value and Pricing Factors
Tanzanite pricing depends on several factors:
1. Color 🎨
The most valuable stones display:
- Deep saturated blue
- Strong violet flashes
- Even color distribution
2. Clarity 🔍
High-quality tanzanite is eye-clean. Visible inclusions reduce value.
3. Cut ✂️
A well-cut stone maximizes pleochroism and brilliance.
4. Carat Weight ⚖️
Larger stones (5+ carats) with top color command premium prices.
🌟 Investment Potential
Because tanzanite is mined in only one location and is a finite resource, many experts believe its value will continue to increase over time.
Government regulations in Tanzania have also limited mining exports, further tightening supply.
This makes high-quality tanzanite a strong candidate for long-term gemstone investment. 💼💎
🛠 Mining and Ethical Considerations
The mining region is divided into four blocks (A, B, C, D). Block C is the largest and most productive.
Efforts have increased in recent years to improve:
- Worker safety
- Ethical sourcing
- Fair trade practices
Buying from reputable suppliers ensures responsible sourcing.
