Blue Kyanite Rock + Dude Rocks Card

The Blue Kyanite Rocks comes with a Dude Rocks informational card for your son to learn more about the stone. Here is what it says:

Blue Kyanite has a bladed crystal structure and is found in metamorphic rocks formed under extremely high pressure. The blue color comes from aluminum present at its formation. Because Kyanite is highly heat resistant, it has a number of industrial applications including use in spark plugs, brake pads, porcelain and furnace manufacturing. One of the largest producers of Kyanite is found in Virginia.

Note - since this is a thinner rock we will send multiple when ordered.
