It is an aluminum-zirconium-titanium-oxide material with some other elements mixed in. A sapphire like thing. Some claim it is harder than diamond, others that it is just denser.

[demoncase]

"The theoretical density (calculated from the crystal structure) is 4.12 g/cm3, higher than a diamond with 3.52 g/cm3. However, this doesn't translate, as erroneously reported by some media, in a higher hardness"

"The largest stone discovered so far is 0.25 oz"

Tells you why no-one will be making knives from this- it's rare (so massively expensive), only found in small sizes (so not going to be blade stock) and actually isn't harder than sapphire.

Theoretical density is always a bad sign- that tells you there isn't a big enough non-porous lump to drop it into water to do a standard gravimetric density test

Does look pretty though. :)
