Is the rare gem Tanzanite a genuine gemstone?
If you've been exploring the world of gemstones, you've likely come across the mesmerising blue-violet hues of tanzanite. Often compared to sapphire, this captivating stone has become increasingly popular in recent years. But with its rising fame, some have asked about its authenticity.
Is tanzanite a genuine gemstone? Let's delve into the fascinating world of this enchanting gem …
The Origin of Tanzanite
Discovered in the Merelani Hills near Mount Kilimanjaro in Tanzania in 1967, tanzanite is a relatively new addition to the world of gemstones. It's a variety of the mineral zoisite, and its unique blue-violet color is the result of the presence of vanadium in its chemical composition. Due to its exclusive origin, tanzanite is 1000 times rarer than even diamonds, making it highly sought after in the jewellery world.
Authenticity and Formation
Tanzanite is indeed a genuine stone, formed over 585 million years ago through a series of geological processes. The unique conditions required for its formation – a combination of extreme heat and pressure – mean that tanzanite is only found in a small area of Tanzania. The limited supply of this gemstone makes it even more precious and unique.
Value and Rarity
Given its scarcity, tanzanite has a higher price tag compared to other gemstones. However, its value is derived not only from its rarity but also from its stunning color and pleochroism – the ability to display different colours when viewed from different angles. This captivating characteristic adds to its desirability in the world of gemstones.
Imitations and Treatments
While tanzanite is a genuine stone, it is essential to be aware of imitations and enhancements. There are synthetic stones sold as natural tanzanite. To ensure you're purchasing genuine tanzanite, ask for gemological report. Heating is a regular treatment of Tanzanite, as it mainly comes out the ground with a brownish tinge. Although classed as a treatment, heating does not affect the value of tanzanite. All my Tanzanites are certified by a GIA Gemmologist using various tools and techniques, such as:

Specific Gravity Hydro Scale, Ultraviolet lamps

And all examined, certified gemstones are then micro laser inscribed on their girdles for blockchain security purposes.
In conclusion:
Tanzanite is undeniably a genuine and beautiful gemstone, valued for its rarity, vibrant hues, and pleochroic properties. Make sure to research and verify your tanzanite's authenticity before purchasing, if it seems to good to be true, it probably is.
