Turn your loved one into a diamond!

Hideously tacky, or the only foolproof (if flashily pricey) way to prevent a zombie apocalypse? From Reuters:

Diamonds really are forever. Algordanza, a small company based in the mountainous southeast of Switzerland, uses the ashes of dead people to make diamonds as a permanent memento for their nearest and dearest.

[...] Algordanza -- which means "remembrance" in the local language Romansch, spoken in some parts of the Swiss canton of Grisons -- is one of a handful of companies offering artificial diamonds that have sprung up as the technology has improved.

U.S.-based LifeGem and Britain's Phoenix Diamonds, for example, also offer diamonds made from hair, which contains more carbon than ashes meaning a gem can be created from the hair of a living person, or from someone who has been buried rather than cremated. LifeGem even offers diamonds made from dead pets.
