Fine Grade Rough Kyanite Crystals 

Rough kyanite crystals from our collection of rocks and minerals.

Kyanite is an unusual mineral because the hardness is different across the width and length of the same crystal.

When tested lengthways, it grades between 4.5 to 6 on the Mohs scale., but across the width, it's 6 to 7.

Although relatively hard, kyanite crystals are brittle so must be handled carefully. 

Tiny specs of silvery-white mica tend to remain on your hand after handling kyanite. 

These bladed crystals are rough and unpolished. 

Each piece in the dropdown menu represents one bladed kyanite crystal. Only one of each is available, so please do not adjust the quantity after making a selection.

As an example of size/weight, the piece of kyanite in photo 3 weighs 25.5 grams. The piece in photo 4 is 12.9 grams, and the piece in photo 6 is 7.3 grams.
