Tanzanite, discovered in 1967 in the foothills of Mount Kilimanjaro, is one of the rarest gemstones, found only in a small area of Tanzania. Its mesmerising blue-violet hue, which shifts between blue, violet, and burgundy depending on the light, has captivated gem enthusiasts worldwide. Tiffany & Co. recognised its beauty and gave it the name "Tanzanite" after its country of origin, launching it into global prominence. Tanzanite is often associated with transformation, new beginnings, and spiritual awakening.

When selecting tanzanite, the most sought-after stones exhibit a deep, saturated blue-violet colour, with the ability to shift colours in different lighting. The gem should be eye-clean, with no visible inclusions, and well-cut to maximise its brilliance. Due to its relative softness, tanzanite should be handled with care and set in protective settings if used in rings. As a rare and valuable gemstone, it's essential to purchase tanzanite from reputable sources and ensure that it comes with a certification of authenticity. Tanzanite's exclusivity and unique beauty make it a prized addition to any jewellery collection.
