Would you wear a diamond (synthetic) made from the ashes of a deceased loved one?
No - I'm not making it up - there's a company that does just this.
"The ashes-to-diamond process is fairly straightforward, they send 200 grams of cremated remains to its laboratory in Switzerland. The carbon from those ashes is then filtered out to more than 99% purity and refined into silky, black graphite. A machine then applies volcano-like pressure and temperature: Nine hours later, a synthetic diamond -- which has a bluish rather than clear tint, owing to boron found naturally in the body -- is born."
