Diamond Handbook (3rd edition, 2018) by Renee Newman

The 3rd edition of the Diamond Handbook (2018) updates jewelry professionals and serious diamond buyers on new developments in diamond grading, treatments, synthetic diamonds, imitations and fancy-color diamonds. Using close-up photos, it shows how to make visual judgments about clarity, transparency, brilliance and cut quality.

Basic and advanced methods of detecting diamond imitations, treatments and manmade diamonds are discussed and illustrated. Tables, charts, diagrams and more than 350 photos are included making this an excellent reference on natural, treated and CVD & HPHT diamonds.

Highly recommended book order here.
