Gregg Ruth is a designer and manufacturer of fine jewelry based in Malibu, California.

For well over three decades, Gregg Ruth's high-profile collections have been sought after by admirers from around the world. But Ruth’s own passion for beautiful jewelry design began in his parent’s jewelry store in Pennsylvania. "We started the line with nine pairs of earrings, six rings, two rings and an Armani suite - and an Audi that I drove past the speedometer breaking."

In 1995, Gregg turned his attention to diamond intensive jewelry and began to focus his design aesthetic around the use of fancy color diamonds and important colored stones. The company quickly became known as an industry leader in yellow and pink diamond center stone pieces and helped to popularize these rarest of diamonds. It then expanded it's world of color into the hues of emerald, ruby, and sapphire. A Gregg Ruth colored stone piece, whether it be a pendant valued at $10,000.00 or a necklace valued at $150,000.00 is instantly recognizable by its bright and highly saturated gemstones. A constant innovator and industry leading visionary, Gregg Ruth is dedicated to the creation of jewelry which is fashion-forward yet timeless and which can be worn and treasured for decades.
