To some extent, the death rituals are still used today in England. London at least. the featherd horsed and the glass hearse. Some times a dirge. One of the Kray brothers had a big one, with a band in the procession and hundreds of followers. That was in the East End and we went to watch. Others do the same thing but on a smaller scale. I imagine even the smaller ones are expensive. I think this goes goes on all over the UK, of the families can afford it.
I just pay for cremations and be done with it.
Oh, mourning jewelry and such are very collectable but not used much in modern times. They were usuall jet, amethyst and hair. Not always the deceased, BTW. Women wore their hair long in those days and used their own hair receivers to collect the material to make everything from picture frames to rings and pins of the dead.
