Rough kyanite bladed crystals in a wide variety of sizes. Kyanite is a translucent mineral that's unique because its hardness differs within the same crystal. When tested lengthways it grades between 4.5 to 6 on Mohs scale of mineral hardness but across the width it grades 6 to 7. This characteristic along with the fact that it's also very brittle makes kyanite a difficult stone to cut.
The price stated is for 50 grams of rough untreated kyanite crystals. With each piece being a different weight it's not possible to say exactly how many you will receive. Both groups of kyanite crystals in our last photograph weigh 50 grams.
