Her more whimsical lines such as Harley Honey and Biker Babe is an upscale biker look, and Horsin Around captures the equestrian crowds.

In late 1997, Dian debuted her first faceted line Watercolors. Before she discovered her penchant for jewelry design, Malouf traveled 40,000 miles and ten years researching the reclusive Texas ranchers for her first book, The Cattle Kings of Texas (now out of print.) While working from her 175-year old adobe home in Santa Fe, New Mexico to complete The Cattle Kings of Texas, Dian began searching the area for a silver ring of significance. When she couldn't find one to her liking, she decided to design her own. And so the jewelry business began. Dian also designs signature one-of-a-kind pieces featuring unique stones and artifacts. Bold and powerful, they have a distinctive Malouf style. Celebrities such as Cher, Elton John and Linda Ronstadt are among those who have taken a liking to the Dian Malouf line.

Malouf is a native of the South Texas Brush Country near the Mexican border. She shares time between her homes in Dallas and Santa Fe with her husband Don. Dian is also the mother of four children. Dian continues to create original jewelry designs and is has now completed her book "Seldom Heard," which is available now.
