Kathy Young, 28, enrolled in a jewelry-making course for adults at Forest Hills High School in New York two years ago while working as a preschool teacher in Queens. She loved it so much she quit education and plunged into jewelry designing. This past Christmas her graceful silver pendants sold out at Madison Avenue's Georg Jensen and were in short supply at Bloomingdale's. An editor at Vogue, who featured the jewelry in a fashion layout, says, "It fits into a woman's life today." Kathy explains that her designs "can be worn with blue jeans. It's not tacky like wearing your mother's diamond pin." The pendants can be suspended on silk cords, leather laces or chains. Kathy has also created a line of buckles and wrist cuffs for both women and men. Although she hand-finishes and hand-stamps each piece herself, the actual casting is done at a foundry. It takes two days of polishing "until 3 or 4 in the morning" to produce 25 pendants. The silver ones sell for $16 to $200, the gold from $60 to $2,000. Kathy came to New York from her native Buffalo in 1971 after her marriage broke up. Although she can barely keep up with orders for her jewelry, she doesn't plan to hire anyone else. "It will always be just 'Kathy Young.' "

Steve Hartunian, 21, is being called the "Six and Three Quarter Million Dollar Man." The nickname comes not from flexing bionic muscles but from salesmanship. The Encino, Calif. native was honored as the "Top Over-All Sales Producer across the U.S. and Canada" in 1976 by Century 21, an international network of 35,000 real estate salesmen representing 3,500 offices. During the first 10 months of 1976, Hartunian sold more than 50 houses in the San Fernando Valley at an average price of $80,000. In October he switched to apartment buildings and racked up $2.75 million in sales before the end of the year. Hartunian got into real estate after a brief career as a car salesman. "The potential wasn't there," he says. "I wanted to make more money faster." He was issued a real estate license at 19. Steve won't divulge how much he earned last year, but if he averaged three percent commission he grossed well over $200,000. At any rate, it was enough for a Cadillac Seville to take his clients apartment-house-hunting and a sporty Ferrari for his own pleasure. Next year Steve plans to open his own office and write a book about selling real estate.
