Adamantine spar
Adamantine spar is a shiny rock that's super hard and sparkly. It's actually a kind of mineral called corundum, but we call it adamantine spar because it's so tough and strong it's almost like a superhero!
You might know that regular rocks can be scratched with something sharp like a knife. But with adamantine spar, it's the complete opposite - it's so strong that it can actually scratch other things, including rocks like quartz and even steel!
Adamantine spar is also really pretty because it has a special kind of light reflection called "adamantine luster." When light hits the surface of the rock, it bounces back in all different directions, creating a sparkly effect that makes it look like it's covered in little diamonds.
People have been using adamantine spar for thousands of years to make all kinds of things, from cutting tools to jewelry. Even today, we still use it to make things like industrial grinding wheels and electronic screens. So next time you see a shiny rock that's super tough and looks like it's covered in diamonds, you'll know it might just be adamantine spar!
