To obtain a Graduate Gemologist Degree, Sydney had to take a series of courses and labs, culminating in final testing. Her Graduate Gemologist Degree consists of a Graduate Diamonds Degree and a Graduate Colored Stones Degree. She is certified to evaluate diamonds and gemstones by the 4 Cs (color, clarity, cut, and carat weight), the International Diamond Grading System and the Colored Stone Grading System. She also holds a Graduate Pearls Degree and Applied Jewelry Professional credentials.
Upon graduating from GIA, Sydney’s wife, Michelle Strong, gifted a personalized lab coat emblazoned with the title “Doc of Rocks” in gold embroidery. Sydney is officially our Doc of Rocks at llyn strong fine art jewelry, and she certainly lives up to her nickname.
