Aunt Sally?

Ever see something that just leaves you scratching your head in bewilderment? In BeautyXpose’s “WTF of the Week,” we share our favorite befuddling moments for your pleasure.

They always say that diamonds are a girl’s best friend. But what if the precious gem you were wearing was made out of your best friend? That’s a possibility according to LifeGem Created Diamonds, which offers diamonds “created from the carbon of your loved one as a memorial to their unique life, or as a symbol of your personal and precious bond with another.”

And if that thought didn’t gross you out enough, here’s another. The company recently made headlines when a Michael Jackson fan revealed a LifeGem diamond would be created from a lock of the singer’s hair that was singed during the infamous Pepsi commercial.

When pondering my own LifeGem, Kristin helpfully suggested I get a diamond-encrusted dog collar created out of the remains of my current dogs, as a lovely keepsake for future doggie generations. Yeah — no thanks.

Hey, it may offer comfort to some, but for us, LifeGems deserves a resounding “WTF.”
