Since they do not believe in an afterlife, they take good care of their deceased. Of course, the richer one is the better casket they will receive.

High officials usually have decorated coffins with a viewing window for everyone to see. The thought being, they were A. rich B. smart enough to create a coffin that can preserve a body well or C. rich enough to buy the rights to the coffin that is super cool. The more the body can be seen, the more "sure" one is of their technology and so want to flaunt it off.

All coffins are different, but can be very similar in style.Usually only Richer people/more inventive people create their own casket as a testament to their genius or whatever. Or one can steal a coffin.

Grave robbing is a big thing in Sol because of the uniqueness and status they have. Some very rich people / high officials hire guards to keep watch over their deceased relatives either in their own private estate, or in a private cemetery.

Because of the unique preservation techniques, body looting is also very big.
