Collection: Green kyanite

Green cyanite (also called green kyanite ) is a rare variety of cyanite, a silicate mineral belonging to the neosilicate group, with the chemical formula Al₂SiO₅ (aluminium silicate).

🔹 Origin of the name

The name "cyanite" comes from the Greek kyanos , meaning "blue," as the most well-known form of this mineral is blue in color. Green cyanite, although rarer, derives its name from the same root, but has a distinct green color .

🔬 Mineralogical characteristics

• Chemical formula: Al₂SiO₅

• Crystal system: Triclinic

• Hardness: Very variable depending on the axis (between 4.5 and 7 ) — a unique characteristic.

• Cleavage: Perfect along a plane, which makes it fragile at the waist.

• Density: 3.6 to 3.7

• Luster: Vitreous to pearly

• Transparency: Transparent to translucent

🌿 Green color

The green color of cyanite is due to the presence of impurities , including:

• Iron (Fe)

• Vanadium (V)

• Chromium (Cr) in some cases

It can vary from pale green to emerald green depending on the concentration of these elements.

🌍 Origin

Green kyanite is mainly found in:

• Brazil (very good quality gems)

• India

• Nepal

• Tanzania

• Kenya

• Zambia

💎 Uses
