It’s people! Diamonds are made of people!
At least they can be from now on. Lifegems will turn the remains of your loved ones into a diamond for you to wear and creep everyone out with for years to come. From the web site:
The LifeGem® is a certified, high-quality diamond created from the carbon of your loved one as a memorial to their unique life.
Yeah, it’s a little wacky, but it’s also a pretty cool idea. I’ve always wanted to be donated to science after I expire, but being reincarnated as one of the hardest and coolest-looking materials in the world is definitely a close second.
