Fine Grade, Rough Kyanite Crystals
Rough kyanite crystals from our collection of rocks and minerals.
Kyanite is an unusual mineral because its hardness differs across the width and length of the same crystal.
When tested lengthways, kyanite 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 hands after handling kyanite.
These bladed crystals are rough and unpolished.
Each piece in the dropdown menu represents one bladed crystal. Only one of each piece is available.
As an example of the size and weight, the 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.
