About Martin Katz Jewelry

Martin Katz is a Los Angeles based luxury jewelry designer known for transforming rare stones into artistic creations. His contemporary take on vintage jewelry reflects his passion for Edwardian and Art Deco jewelry, and his pieces are often referred to as “contemporary jewelry with an old soul.”

Born in South Bend, Indiana, Katz earned degrees in psychology and business at Indiana University in 1978, where he began selling jewelry on campus. After graduation, Katz moved to Los Angeles and became a salesman at the Beverly Hills Laykin et Cie, the jewelry salon of I. Magnin, where he cultivated a passion for vintage jewelry and rare gemstones.

Martin Katz founded his eponymous company in 1988, and initially the young jeweler focused on sales of vintage pieces. As his clients began to request specific pieces to round out their vintage collections, Katz turned to his own designs to fill the void, and he quickly distinguished himself with his hand-crafted, couture-quality pieces inspired by his deep love of vintage jewelry. His reputation continued to grow, and sales of his contemporary designs soon eclipsed vintage sales.

Katz’s work today features carefully chosen colored stones, including Paraiba tourmaline, red spinel, and Alexandrite, as well as pink and yellow diamonds. Each piece is made with meticulous attention to detail, and is either one-of-a-kind or limited in production, numbered, and signed.

Martin Katz’s jewelry is well known on the Red Carpet, and has adorned A-list celebrities from Barbara Streisand and Angelina Jolie to Johnny Depp and Mark Wahlberg. Other projects have included a black and white diamond bra for Victoria’s Secret, jeweled sunglasses for Ray-Ban, and The Jewel Suite, a Katz designed, Art Deco inspired penthouse suite at The New York Palace Hotel.
