Tanzanite is a precious stone that has recently entered the market. Tiffany & Co was the first company to, thanks to a great marketing campaign, introduce it to the international market.
The most important gemological variety of Zoisite is the Tanzanite. It owes this name to its place of origin, Tanzania, still the place of the only deposits found.
Because it is only mined in a particular area of Tanzania, deposits are likely to be depleted within a few decades.
The Tanzanite is usually a violet color with brown tones. To avoid these brownish tones, the Tanzanite is generally treated, achieving much more intense blue-violet colors.
We took several photos:
We take photos with daylight (no lightbox and no extra lighting at all).
And we take photos and videos on mirrors in a light box with extra lighting (this kind of photos clearly show the quality of the cut and the clarity of the gem).
MdMaya Gems uses the following clarity scale when grading gemstones.
Setting aside translucent and opaque gemstones, the first classification to take into account is:
EYE CLEAN: Appears clean to the unaided eye. (Type 1, 2 and 3)
Type 1: Minute inclusions difficult to see with the unaided eye.
Type 2: Minor inclusions easy to see with the unaided eye.
Type 3: Noticeable inclusions apparent to the unaided eye.
Type 1: Minor inclusions somewhat easy to see with the unaided eye.
Type 2: Noticeable inclusions apparent to the unaided eye.
Type 3: Obvious inclusions very apparent to the unaided eye.
HEAVILY included: prominent inclusions that have a negative effect on appearance or durability.
SEVERELY INCLUDED: prominent inclusions that have a severe effect on appearance or durability or both. (Type 1, 2 and 3).
All our gemstones have been analyzed by a qualified gemologist. Each precious stone comes with a gemological certificate to guarantee its authenticity, as well as describing its unique characteristics.
