Jewelry is a family affair for the California-based, Armenia-bred designerArman Sarkisyan majored in architecture in his native Armenia. “Knowledge of structure and functionality has helped with my engineered pieces like the more complex lockets and such,” he says. But the Los Angeles–based designer began his jewelry training long before university—in his father’s studio, in their home country, at age 12. The two men still work side by side, producing Arman’s gilded, Gothic-influenced 22k gold, oxidized silver, and gemstone wonders. The toughest part about working with his father, Hamlet? (We won’t tell—we promise!) “He is the Order and I am the Chaos; he is one at a time and I’m at least 20,” says Sarkisyan. So what’s the best part? “No limits to what can be done.”Left: tourmaline and tsavorite ring; right: emerald and chrysoprase ringAge: 40Number of years i
