Giganti's pretty wholesome himself, with a beautiful wife and six kids (she wants two more). One wall of his Clayton Road store is lined with certificates from the Gemological Institute of America, but after graduate work there, he left decadent Los Angeles to come home. Rubies and pearls tumble through his veins -- his grandfather was an Italian jeweler in Cuba -- but simple courtesies flow alongside them. When a young man, smitten, decided he had to propose that very night, he called Giganti and begged him to bring the engagement ring. Giganti obliged, calling from his cell phone when he reached the apartment building. "I'll meet you out back," the guy blurted, and raced downstairs, hands shaking like fern leaves in a strong wind, to grab the ring from trusted hands and take hold of his shining future.
