“If I’m ever stuck in traffic or I’m stressed out by circumstances in my life, the mere acts of looking at and touching one of these shift knobs drains away the stress,” the maker notes on its website, gemstoneshiftknobs.com. You may never need to buy another, either. About a $209 knob built from petrified 225-million-year-old wood from Madagascar, the maker says it “will match Mother Nature and offer a 225-million-year warranty on it.”
