If you have ever seen a Tanzanite gemstone before you will know it’s known for its the dazzling blue-violet colour. I first learnt about Tanzanite’s in detail whilst I worked for Tiffany & Co, a brand who were key to bringing this gemstone to the wider market in 1968.
Tanzanite’s are found exclusively in Northern Tanzania. This geographic exclusivity not only adds to their mystique but also their value. The formation of tanzanite’s requires specific conditions over millions of years. The result is a gemstone displaying different colours when viewed from different angles: shades of blue, violet, and burgundy.
The best tanzanite’s exhibit a deep, velvety blue with a hint of violet, a colour range that has become synonymous with luxury and sophistication. Unlike other gemstones, tanzanite’s owe their stunning hues to the presence of vanadium within the zoisite mineral. When heated, either naturally or through artificial enhancement, these elements interact to produce the gem’s signature colours.
Grading and Value
The value of a tanzanite is determined by several factors: colour, clarity, cut, and carat weight. Among these, colour is the most critical. The most coveted tanzanite’s are a rich, deep blue with violet undertones, often referred to as “AAA” grade. Clarity also plays a significant role; high-quality tanzanite’s are eye-clean, meaning they lack visible inclusions.
Caring for Tanzanite’s
To maintain the beauty and brilliance of tanzanite’s, proper care is essential. Despite their hardness, tanzanite’s are relatively brittle compared to other gemstones like sapphires or diamonds. It is advisable to avoid exposing them to harsh chemicals or extreme temperatures. Regular cleaning with mild soapy water and a soft brush will help keep tanzanite’s looking their best. Storing them separately from other jewellery can prevent scratches and damage.
The Appeal of Tanzanite’s as an Investment
Tanzanite’s are estimated to be 1,000 times rarer than diamonds. This geographic exclusivity significantly enhances their value. As the mining areas become increasingly depleted, the supply of tanzanite’s is expected to diminish, driving up prices over time.
Since their discovery in 1967, tanzanite’s have gained immense popularity in the jewellery market. Their unique blue-violet hues and ability to display different colours when viewed from various angles make them highly desirable. As awareness and appreciation for these gems continue to grow globally, demand is likely to rise, further enhancing their investment potential.
Tanzanite’s offer a compelling blend of rarity, beauty, and investment potential. As their availability continues to dwindle and their popularity grows, these stunning gemstones are poised to become even more valuable.
Whether you're an avid gemstone enthusiast or simply drawn to the mesmerizing colour and beauty of tanzanite’s, it’s a gemstone that is sure to become a favourite in your collection
