For those who want something special to commemorate the passing of a loved one, I commend your attention to a new option for that urn full of ashes. Other than using them on icy sidewalks, that is, as a funeral home in England did recently.
LifeGem, promises to take your loved one's ashes (which are primarily carbon, at this point,) and form them into a diamond. The man-made gem is a genuine diamond, with all the sparkle and durability of the original. The price is a bit steep, though; a carat stone will set you back almost $20,000. Still, I'm sure some people would gladly pay this much to keep their spouse wrapped around their finger.
