Master Goldsmith

Our Master Goldsmith, Darrell Martinez continues to perfect his expertise and stays up to date with current trends in design and metal work. He is highly skilled in the art of setting all types of gems as well as working with precious metals. Darrell is one of a few goldsmiths in the area to use a laser welder, a technique used to join multiple types of metal together through a heat source allowing him to work on an item of jewelry with out removing the stones. He also teaches his skills to a new generation of goldsmiths. In 1987, Darrell earned his Graduate Diploma in Jewelry Manufacturing Arts from the Gemological Institute of America.
