Warning — matters of questionable taste ahead, but this seems so outrageous I had to mention it. A company called LifeGem wants to help you remember your loved ones in a more permanent and beautiful — and I think, pretty sick — way. LifeGem will take the carbon cremated remains of the dearly departed and turn them into blue, yellow, or red diamonds, at prices ranging from $4,000 to $28,000. This way, you can literally keep your relatives always near your heart, or close at hand.
