Here's an interesting site,
LifeGem. It's a company based in the US (has branches in UK as well) that offers to create artificial diamonds from the cremated carbon remains of a loved one, whether of the genus
homo sapiens,
canidae,
felidae, or any other species you like. The gems are offered in 2 colors, blue or yellow. They're really quite beautiful.
On the other hand, maybe it's just me, but there's something... weird about the idea of carrying around the remains of a beloved family member. Granted, it's technically the same as carrying a locket of hair around in a... locket (no pun intended). It just seems a bit..
gelee to me to be carrying around what's technically the remains of somebody you used to love. What do you think?
