Tanzanite: The Beautiful Blue Gemstone

History of Tanzanite: From Discovery to Popularity

Tanzanite is a rare and valuable gemstone that was discovered in the late 1960s in Tanzania, East Africa. The story of tanzanite's discovery and rise to popularity is a fascinating one, and it highlights the intersection of geology, commerce, and culture.

In 1967, a Maasai tribesman named Jumanne Ngoma discovered some blue-purple stones in the Merelani Hills in northern Tanzania. He brought the stones to a local prospector, Manuel de Souza, who recognized them as a potential new gemstone. De Souza was working for a company called Tiffany & Co, which had sent him to Tanzania to search for a new blue gemstone that could rival sapphire.

De Souza sent some of the stones to Tiffany & Co.'s headquarters in New York, where they were identified as a new variety of zoisite. Tiffany & Co. named the gemstone "tanzanite" after its country of origin and began marketing it as a rare and exotic gemstone.

The discovery of tanzanite caused a sensation in the gemstone world, and its popularity quickly spread. The gemstone was featured in magazine articles and advertisements, and it became a popular choice for engagement rings and other jewellery.

One of the factors that contributed to tanzanite's popularity was its unique colour. Tanzanite can range from a pale blue to a deep violet-blue, and its colour can shift depending on the lighting and viewing angle. This colour-changing property, combined with tanzanite's rarity, made it a highly desirable gemstone.

Another factor that contributed to tanzanite's popularity was its association with Tanzania and the Maasai people. The Maasai are a semi-nomadic tribe that has lived in Tanzania and Kenya for centuries. They have a rich culture and are known for their distinctive clothing, jewellery, and traditions.

Tanzanite became a symbol of Tanzania's natural beauty and cultural heritage, and it helped to boost the country's economy. Tanzanite mining became an important industry in Tanzania, and the gemstone was a major export. Tanzanite also provided employment opportunities for the local population, and it helped to fund community development projects.

However, the rapid rise in demand for tanzanite also created some challenges. Illegal mining and smuggling became major problems, as people sought to cash in on the high prices that tanzanite could fetch. The Tanzanian government responded by setting up a tanzanite certification system to regulate the industry and prevent illegal activities.

Today, tanzanite remains a popular and highly prized gemstone. It is still mined exclusively in Tanzania, and it is known for its rarity, beauty, and cultural significance. Tanzanite has also been recognized as a birthstone for December, further cementing its place in the world of gemstones.

In conclusion, the history of tanzanite is a story of discovery, commerce, and culture. The gemstone's unique colour and association with Tanzania and the Maasai people helped to make it a popular and highly prized gemstone. While tanzanite's rise to popularity was not without challenges, it remains an important part of Tanzania's economy and cultural heritage.


Colours and Grading of Tanzanite: How to Choose the Best Stone

Tanzanite is a rare and highly prized gemstone that is prized for its unique colour, beauty, and rarity. Tanzanite is a variety of zoisite mineral that is found exclusively in Tanzania. It is a relatively soft stone, with a hardness of 6.5 to 7 on the Mohs scale, making it somewhat susceptible to scratching and chipping.

One of the most distinctive physical properties of tanzanite is its colour. Tanzanite can range in colour from a pale blue to a deep violet-blue, with the intensity of the colour depending on the quality of the stone. The colour of tanzanite can also shift depending on the lighting and viewing angle, giving it a unique and captivating character.

Tanzanite is a pleochroic stone, meaning that it displays different colours when viewed from different directions. In the case of tanzanite, the stone can appear blue, violet, or brownish-yellow depending on the viewing angle. This pleochroism is one of the factors that makes tanzanite such a prized gemstone, as it gives each stone a unique character and personality.

Tanzanite also has a relatively high refractive index, meaning that it can reflect light in a way that creates a high degree of brilliance and sparkle. This property gives tanzanite a dazzling appearance that makes it a popular choice for engagement rings, earrings, and other jewellery.

Tanzanite has a specific gravity of approximately 3.35, which is slightly higher than most other gemstones. This density gives tanzanite a substantial feel and weight, which can be another attractive feature for those who prefer heavier, more substantial jewellery.

In terms of clarity, tanzanite can be quite transparent and free of inclusions. However, it is not uncommon for tanzanite to have some inclusions or surface imperfections. These imperfections can affect the value of the stone, with clearer and more flawless stones being more highly prized and valuable

Finally, it's worth noting that tanzanite is a relatively fragile gemstone, and it can be susceptible to chipping and cracking if it is not handled and cared for properly. Tanzanite should be stored separately from other gemstones to avoid damage, and it should be cleaned carefully and gently with a soft brush and mild soap to avoid scratching.

In conclusion, the physical properties of tanzanite are what make it such a unique and highly prized gemstone. Its distinctive colour, pleochroism, high refractive index, density, and transparency all contribute to its beauty and desirability. However, it is important to handle and care for tanzanite carefully to avoid damaging it and compromising its value.
