Raw tanzanite, scientifically known as blue zoisite, is a deeply coloured gemstone found in only one place on earth. Discovered in the tanzanite mines of Africa, these natural, unheated tanzanite stones are one of the rarest gems known.

The tanzanite colours are shades of purple, violet, indigo, blue, cyan, green, yellow, orange, red and brown with beautiful deep displays of colour at all angles of light, just like a trichroic gemstone.

The Value Of Tanzanite Gemstones Is Hugely Associated With The Clarity Grade Of Each Stone

Unlike diamonds, raw tanzanite is 1000 times rarer! Add a pop of colour and a scarce gem to your jewellery collection with a beautiful tanzanite birthstone.

Clarity is a crucial factor in determining the value of a tanzanite gemstone, and it is a measure of the lack of inclusions within a gem. Inclusions are often crystallized minerals that exist as imperfections inside a stone. Tanzanites have truly breathtaking properties that artificial diamonds can’t replicate. This makes them an excellent alternative option for those looking for something different from your standard diamond dress ring.

The Gemological Institute of America (GIA) is a trusted authority on gemstone grading, as are many other international & local grading laboratories. A tanzanite gem has a very wonderfully rich hue that is unmistakable, but the clarity grade of each stone plays a big role in determining its value. If the tanzanite crystal has visible inclusions, then the value will be significantly lower due to rarity & aesthetic appeal. With expert assistance from our gem specialists, rest assured that you will get an accurate representation of every precious stone, allowing you to buy confidently with us at no risk.

The Importance Of The Tanzanite Gemstone Cut

Tanzanite is a trichroic stone (when unheated), which gives it the ability to reflect light from different spectrums such as deep blues, lighter blues, and even bluish violet hues under natural light or incandescent light. Unheated tanzanite is a type of gemstone that has not been heated or treated in any way. This means it is pure and unaltered, the way nature created it.

The cutting process plays a huge role in tanzanite’s colour blends. A natural tanzanite gemstone is truly beautiful to behold, particularly when cut with skill and care. For example, a December birthstone tanzanite gem with refined cuts, delicate facets, and brilliant lustre yields more value. Lucky for you, our tanzanite jewellery collection includes precision cut tanzanites that boast vibrant pleochroic colours and sparkle.

Certified Diamond Network offers GIA certified tanzanite stones (as well as other labs) in hand-polished minimalistic shapes and cuts. We always guarantee fair tanzanite stone price points, so there is always something for everyone’s budget! Contact our tanzanite gemstone experts today for detailed information on what constitutes an ‘acceptable’ or ‘AA grade’ Tanzanite stone.

Tanzanite Carat Weight & Price

Before making any purchase, it’s essential to understand the tanzanite price per carat.  Carat weight (equal to 0.2 of a gram) is the measure of a gemstone’s weight, and it can be used as an indication of the size and rarity of a particular stone. The value of this rare gem is heavily influenced by carat weight and availability in the global tanzanite market. The higher the carat weight, the more expensive it becomes. In recent years, gemologists have noticed that rough tanzanite stones are becoming increasingly less available. Luckily, we’ve increased our tanzanite stock, so you can invest in this beautiful stone now before the prices go incredibly high!
