Featuring over 1, 000 pages and more than 2, 000 photos, it will delight all, from those relatively new to the amazing world of gemstones to professional gemologists and jewelers long established in their careers. This comprehensive reference guide was the ultimate labor of love and a longtime mission of beloved late Jewelry Television Co-Founder Jerry Sisk, whose undeniable passion for gemstones never waned but only grew stronger with time. His untimely passing left the task of completing the reference guide to our highly skilled team of gemologists and scientists. Volume 1, Prominent Gems, delves into the history, science, lore, sources, treatments and varieties (if applicable) of more than 100 well-known gems, including diamond, ruby, emerald, sapphire and tanzanite. Also included is an easy-to-comprehend study of gemstones and their properties. Volume 2, Noteworthy Gems, explores over 100 other rare and exotic gemstones, such as danburite, kyanite, pezzottaite and sphene. Volume 3, Gallery of Gems, is a pictorial compilation of incredible gemstones, jewelry and mineral specimens sure to leave you breathless as each page is turned. The Professional Edition comes to you encased in a protective slipcase to ensure years of use and enjoyment. Jerry's passion for gemstones is evident as you begin reading Volume 1 and soon find yourself engrossed and will continue as you peruse Volumes 2 and 3. The first edition set is available in limited quantities and only for a limited time. We extend this personal invitation to immerse yourself by taking a delightful foray into the world of gemstones!
