December Birthstone Selection: Tanzanite for Gemstone Enthusiasts
Tanzanite, the mesmerising December birthstone, is a rare and captivating gemstone known for its deep blue to violet-purple hues. This enchanting gemstone is exclusively found near Mount Kilimanjaro in Tanzania, making it a truly unique and sought-after treasure[1].
Properties and Characteristics
Tanzanite is a trichroic gemstone, displaying three colours—blue, violet, and burgundy—depending on the viewing angle[1]. The stone is usually transparent with few inclusions, making it quite clear and brilliant[1]. Its hardness ranges from 6 to 7 on the Mohs scale, which means it is somewhat soft compared to harder stones like sapphire or diamond and can be prone to scratching[1].
The colour of tanzanite is typically deep blue to violet with purplish tones; however, it originally appears brown before heat treatment brings out its vibrant colouration[5]. Every tanzanite stone has a unique 'blend' of pleochroic colors visible when the stone is titled[1].
Care Guidelines
Because tanzanite has a hardness of 6–7, it requires careful handling to avoid scratching or damage. Gentle cleaning with mild soapy water and a soft brush is recommended; avoid ultrasonic and steam cleaners which could damage the stone[1]. Tanzanite should be stored separately from harder gemstones to prevent scratching. It is best worn in jewelry for occasional wear or in earrings and necklaces to minimize the risk of damage[1].
The History of Tanzanite
Tanzanite was first discovered in 1967[2]. It was brought to the Western fine jewellery market by Campbell Bridges[3]. Tanzanite enjoyed steady popularity within the jewellery trade since Tiffany & Co. first started selling the gemstone in 1968[4]. The initial slogan related to the sale of tanzanite was "in Tanzania and Tiffany's."
Tanzanite is the only known source of tanzanite, as Tanzania is the only place it is found[5]. The stone displays trichroic pleochroism, showing three distinct colours: blue, yellow, and pinkish purple[6]. When heated, the yellow color in tanzanite is eliminated, leaving a dichroic gemstone displaying blue and violet[7].
Metaphysical Beliefs
Some believe that tanzanite may strengthen the immune system, aid cell regeneration, and support recovery from coma[4].
In conclusion, tanzanite’s beauty lies in its vibrant colours and rarity, but its moderate hardness necessitates delicate care to maintain its brilliance and integrity over time[1][4][5].
