Sisk Gemology Reference Guide
Jerry Sisk's pursuit of gemstones began in his home state of New York where he discovered the first piece of his gem collection; a brightly colored, water-worn pebble. Many pounds of pebbles later, Jerry became a bench jeweler and connected with Bob Hall, CPA, and later, Bill Kouns, goldsmith. Together, in 1993, the trio founded America’s Collectibles Network (ACN) which successfully evolved into the company known today as Jewelry Television® (JTV). Jerry was a Graduate Gemologist (GIA) and an active member of the International Colored Gemstone Association (ICA). He was adored by coworkers, customers, and vendors alike, and the publication of this book series has been highly anticipated with much excitement. In April of 2012, JCK Magazine named Jerry one of the top five most influential people in the gemstone industry. His legacy lives on in his writings and in the hearts of all those he touched during his lifetime.
