Would give this book SIX stars if I could.
For quite awhile now, Antoinette Matlins "The Pearl Book" has been my go to reference for information relating to pearls. I ordered Renee Newman's "Pearl Buying Guide, Updated 5th Edition" as a more up-to-date reference. It's much more practical for the consumer, with an abundance of excellent photographs showing what (precisely) to look for when shopping for pearls. The book also covers each various type of pearl with greater depth, it well written, very informational, and I'd consider a "must have" book for anyone looking to buy pearls in today's market... or who simply has a passion for pearls.
It was thrilling to find details about lesser known pearls, such as Rainbow Pearls, Cortez pearls, Pipi pearls, and various pearls produced by snails and clams. "Pearl Buying Guide, Updated 5th Edition" opens with 4 pages of photographs depicting the business of cultured pearls, and includes chapters on South Sea Pearls, Black Pearls, Freshwater Pearls and even Pearl Treatments commonly implemented. More important (to me) are the chapters on Judging Luster & Nacre Thickness, Judging Color, Judging Surface Quality, and Judging Make. Each of those chapters includes plenty of full color photographs with comparisons that are clear to any reader.
While Matlin's book has a lot of useful and interesting information, including quotes from Pearl Industry leaders, I'd have to say Newman's book is probably the better of the two for someone who doesn't already know a lot about pearls. Having taken the distance portion of the GIA's pearl course, I do know a lot about pearls, and "Pearl Buying Guide, Updated 5th Edition" is truly almost a condensation of the (expensive) GIA distance pearl course. Happily, it's all in one book that tucks neatly into a tote or purse! Don't leave home to buy pearls without it!
