tanzanite 4.30cts - 12x9mm

Tanzanite belongs to the family of Zoisite and its vivid violet-blue color is caused by the presence of vanadium/ chromium. It is a stone discovered relatively recently, in northern Tanzania, specifically in Merelani - near the foothills of Mount Kilimanjaro. Because of its recent discovery in 1967, this stone is also called a “20th-century gemstone”. Its unique name is inspired by the only place it is found on earth since its discovery (Tanzania) making it a prized and rare gem.

The gem is a soft stone with a hardness of 6.5 on the Mohs scale. It was declared as the December birthstone by the American Gem Trade Association in 2002, along with turquoise and zircon.


HOW IT WAS FORMED AND TREATED

The discovery of tanzanite is mainly attributed to Manuel de Souza, a local Tanzanian Maasai tribesman who stumbled upon a cluster of blue-violet crystals while herding cattle.

Though discovered recently, Tanzanite was formed 585 million years ago under complex geological conditions, accounting for its exclusivity and making it one of its own kind. It was formed from the metamorphism of a type of rock called gneiss, which is very rare in the world. The specific tectonic activity that formed Mount Kilimanjaro favored the formation of Tanzanite, subjected to high pressure and temperature.

Forming as a brownish crystal the tanzanite is trichroic (refracts three colors) before heating and it is brown, blue, and violet in color. Tanzanite can change color depending on the lighting conditions, and it can appear blue, violet, or even reddish-brown. For Tanzanite, it’s a universal process to heat the gems to remove the brown component and make it dichroic. The mining of Tanzanite in Merelani is done in 4 sections (A, B, C, D). Tanzanite found initially in the surface level of block D is naturally dichroic due to the wildfire that happened in the area. Very rarely green Tanzanites are formed naturally. When heated in a furnace, it should be done with care as bubbles or cracks in the gem can increase in size or cause it to burst.

Tanzanite is often cut in a variety of shapes, including cushion, oval, pear, and emerald. The most popular cut is the cushion cut, which showcases the stone's color and clarity.


HOW IT IS GRADED

The meticulous cutting and the workmanship bring out the best shades of the gem. The value of tanzanite is determined by several factors, including color, clarity, cut, and carat weight.

COLOR: The color of tanzanite is often described as a "velvety" or "peacock blue" hue, which can range from pale blue to deep violet blue. The most valuable tanzanite are those with a brilliant and deep blue or violet-blue color and a high degree of clarity. The exact shade can vary from stone to stone, making each tanzanite gemstone truly one-of-a-kind. Rarely tanzanite heat to a green primary color, always with secondary blue/violet hues.

CLARITY: being a relatively clean gemstone, a good-quality gemstone has no inclusions or at least not that is visible and other imperfections. They are radiant and eye clean.

CUT: The cut can elevate the value and beauty of the stone. Gems that have been well-cut with good proportions and symmetry will enhance their brilliance and color.

CARAT WEIGHT: Larger weighing stones are quite valuable, however, they need to be examined for imperfections.
