Reviewing Tanzanite Rings

Reviewing Tanzanite Rings

The tanzanite is one of the most desired stones. It can be found solely near Mount Kilimanjaro, Tanzania. This stone originates from the zoisite family and can be found in radiant blues, vivacious violets and deep purples. It is said to have been formed 585 million years ago but this mysterious stone was only discovered in 1976 by a Masai tribesman who stumbled upon transparent royal blue-violet crystals radiating from the earth. This stone was instantly recognised for its intensity, brilliance and rich colouring. Given it is one of the rarest stones on earth, it makes for the perfect centrepiece in any ring. 

Valuing Tanzanite

The tanzanite comes in a variety of shapes which is why it is so often used in rings. When buying this African gem, it is important to determine the quality by examining the stone’s cut, colour, clarity and carat weight. 

This is a trichoic stone which means it reflects different colours. The most sort-after tanzanite stones are rich violet-blues with red flashes of light. As a pleochroic gem, they shine three different colours when viewed from different directions and they can be found in a mix of vivid blues and purples. The more saturated the colour, the more valuable the stone.  The paler colours tanzanites are more common and less valuable. 

Regarding clarity, tanzanites may have inclusions that reduce the value of the stone. Look for stones that do not have inclusions that are visible to the eye. Tanzanites without inclusions that are visible under a microscope are highly valuable. Inclusions that may lead to stone damage such as fractures dramatically decrease the stone’s value. 

The cut affects the value and it should not be too deep or too shallow. It should be cut precisely so the light best refracts, resulting in the stone’s brilliance. Tanzanites can be cut into any shape but the most common shapes are oval and cushion cut. 

The carat weight, not to be confused with size, also impacts the value of the stone. 

The colour is most vivid in larger tanzanites, particularly those above two carats. On the other hand, the larger the stones the greater the chance of inclusions and flaws. This makes large and flawless tanzanites very valuable. 

Ring Styles

Tanzanites look gorgeous in many ring styles. Depending on your taste, tanzanite rings can range from the simple solitaire to the oval tanzanite eternity ring. Their violet-blue colour looks particularly stunning when set in white gold that emphasises their brilliant blue. 

Caring for Your Ring 

Tanzanites are soft stones and jewellers must take extra care when setting them into your ring and when cleaning your ring. It should not be cleaned by the ultrasonic cleaners that are used by jewellers as tanzanites have a sensitivity to this. When having your ring cleaned, ask the jeweller what cleaning processes they use for tanzanite jewellery. It is important to not only clean the tanzanite ring with care but also to wear it with care. These rings cannot be exposed to sudden temperature change and are softer than many other precious stones such as diamonds and sapphires.
