Mark Christensen remembers working a construction job in 2005 when a friend climbed a roof and came down with his pockets filled with agates.
That moment sparked something in Christensen, who's now a full-fledged "rockhound" — an amateur geologist.
His wedding ring is filled with amethyst, a deep purple variant of quartz. He has two other rings, one set with a fire agate and another with an eyeball agate. He wears an agate-beaded bracelet, and a necklace featuring an agate.
