Tanzanite, Nature's Rarest Treasure
Discovered in only one place on Earth — at the foothills of Mount Kilimanjaro — Tanzanite is over 1 000 times rarer than a diamond. Its vivid violet-blue hues and natural scarcity make it one of the world’s most sought-after gemstones. At Shimansky, each Tanzanite is hand-selected, masterfully cut, and set to reveal its extraordinary beauty.
坦桑石的形成
五億八千五百萬年前，在乞力馬扎羅山的山麓，大自然孕育了她最珍貴的寶石。由於其稀有性，它一直未被人知曉，直到 1967 年才在至今世界上唯一已知的產地——坦尚尼亞被發現。
顯著的板塊活動和強烈的熱量形成了乞力馬扎羅山，在此過程中，莫三比克造山帶（地球上礦產資源最豐富的地方之一）也形成了。人們相信，坦桑石原石就是在這過程中形成的。這個過程稱為區域變質，其解釋如下：當板塊相互碰撞時，每個板塊的火成岩（岩漿/熔岩冷卻凝固後形成的岩石）在極端壓力下相互變形。
岩石達到接近熔點，當這種情況發生時，它們會產生美麗的晶體結構。在這個過程中，寶石本質上是由兩塊板塊的結合而形成的。兩個板塊中的每一塊都可能包含各種不同的礦物，因此，可能出現特定於某一區域的組合。這也解釋了為什麼坦桑石僅在世界上一個地區發現。坦尚尼亞這一特定區域內，兩大板塊相互變形，形成了一種在世界其他任何地方都未曾發現過的特殊混合物。
乞力馬扎羅山腳下坦桑石礦床的形成條件十分獨特，地質學家認為，再次出現一批坦桑石的機率只有百萬分之一。
在坦尚尼亞當地人中，流傳著各種各樣的故事和神話，講述這種珍貴寶石的起源。人們普遍認為坦桑石是上帝用雷電點燃周圍山丘而形成的。大火熄滅後，地球冷卻下來，地球深處的岩石變成了藍色。人們也認為這種寶石具有獨特的精神屬性，當地坦尚尼亞人認為坦桑石可以促進精神成長。
坦桑石戒指 人們經常佩戴這種寶石來獲得保護，並認為它具有鎮靜和舒緩的功效。由於其形成的獨特性、稀有性和無與倫比的美麗，坦桑石已成為世界各地備受追捧的寶石。探索 Ayanda 坦桑石珠寶系列 在南非購買坦桑石。
坦桑石的屬性
- 稀有度： 世界上已知的坦尚石唯一產地是坦尚尼亞北部乞力馬扎羅山附近一片長約 4 公里的土地。由於這單一且有限的來源，坦桑石的純度至少比鑽石高出一千倍。由於迄今為止只有一個已知產地，預計在未來 10 至 12 年內將不再發現寶石級坦桑石。
- 顏色： 坦桑石具有獨特的三色性。這意味著，在其粗糙的形式下，它從每個晶體軸散發出三種不同的顏色：藍色、紫色和酒紅色。坦桑石經過切割和拋光後，會呈現從電紫色到鮮豔藍色、深藍色和濃鬱靛藍色等各種顏色。坦桑石的顏色與其晶體結構中的釩和鈦的存在密切相關。
Colour: Tanzanite is uniquely trichroic. This means that in its rough form, it radiates three different colours from each of its crystallographic axes: blue, violet and burgundy. Once cut and polished, Tanzanite ranges from electric violets to vibrant blues, deep royals and rich indigos. The colour of Tanzanite is strongly related to the presence of vanadium and titanium in its crystallographic structure.
- Displays violet, blue and burgundy tones due to trichroism
- Rated 6.5–7 on the Mohs (Mohs scale: a 1–10 scale measuring gemstone hardness) hardness scale (suitable for occasional wear)
- Colour grading: AAA (deep vivid blue-violet), AA (medium), A (light)
Cultural Myths & Investment
- 非洲之謎： 坦桑石的地質結構非常獨特，因此在世界其他地方出現的可能性很小。坦桑石的獨有的非洲血統和其發現的迷人故事已被證明是一個獨特的賣點。對於訪問非洲大陸的外國人來說，坦桑石珠寶是一項特別有吸引力的投資，因為他們可以帶一些獨特非洲特色的東西回家。
- 投資價值： 沒有其他投資能夠像投資最高品質的坦桑石那樣產生如此大的回報。隨著供應減少和需求增加，其價值更有可能上漲。
Investment value: There is no other investment that will yield as great a return as investing in tanzanite of the highest quality. It is more likely to increase in value as supply gets less and demand increases.
- Exclusively found in one known deposit
- Estimated to be depleted within decades
- Rising demand and shrinking supply make high-grade stones collectible

Tanzanite: Frequently Asked Questions
Discover expert answers about Tanzanite’s origin, rarity, care, and what makes Shimansky Tanzanite jewellery truly exceptional.
Tanzanite
Tanzanite is found only in the Merelani Hills near Mount Kilimanjaro in northern Tanzania.
The unique geological conditions that formed Tanzanite exist in only one known location on Earth.
Tanzanite formed over 585 million years ago under extreme heat and pressure during regional metamorphism and tectonic plate activity, creating the unique geological conditions that exist only in the Merelani region.
Tanzanite displays vivid violet-blue hues due to the presence of trace elements like vanadium. It is trichroic, meaning it shows three colours (blue, violet and burgundy) when viewed from different angles.
Tanzanite is a relatively delicate gemstone (6–7 on the Mohs scale). Store it separately, avoid sudden temperature changes, and clean gently with warm soapy water and a soft brush — never ultrasonic cleaners.
- Clean gently using warm soapy water and a soft brush
- Avoid ultrasonic cleaners or harsh chemicals
- Store separately to prevent scratching
- Have settings checked regularly by a jeweller
