Kh'svil has many of the same properties as quartz: it is hard, doesn't damage easy, but can be scratched with sharp objects & high pressure. It can be broken apart & crushed with enough massive force, and is highly resistant to heat. If put under a laser the resin used to bind the quartz matrix will discolor (turn white) when heated too high.

Nothing happens from touching it, and there is nothing contained within the specimen. It's weight is roughly the same as a generic piece of rock.
