The Practical Guide to Jewelry Appraising, authored by appraisal expert, Cosmo Altobelli, Certified Gemologist Appraiser of the American Gem Society, is the latest edition to deliver vital information that is relevant to every seasoned and novice appraiser.

β€œIt is a common mistake to think that gemological knowledge is all that is required in appraising jewelry. This book introduces the reader to the methodologies of appraising and setting up a professional appraisal service.” β€” Cos Altobelli, CGA
The Advanced Personal Property Appraisal course is especially useful if you are interested in the field of personal property appraising. This three-part home-study course covers appraisal theory and the legal guidelines of professional appraising.
