Donna and Randall Rollins

Donna E. Rollins' "aha" moment came to her in a dear friend's home. "I was admiring her stone collection and thought, 'How can I incorporate the healing benefits of crystals and minerals with my love for pottery?'" says the New Hampshire-based artist.

Along with her husband Randall and several staff members—including their daughters—Donna works to infuse their products with the positive energy of quartz. "It's in our clay and glazes," she says, adding that most of the crystals they set into the mug handles are quartz-based too. And though each creator has a slightly different style, they all have a common goal, says Donna: "Collectively, we create what becomes an individual's new favorite mug."
