As I work on the revision of The Listening Heart—thank you Beta readers for such excellent feedback—I was tickled to find an article in the March/April 2019 edition of Lapidary Journal Jewelry Artist magazine entitled “Crystal Hues Persuasion” by Deborah Yonick.
Emeralds are some of the most beloved gemstones in the world—especially by those whose birthdays are in May. However, richly colored, unflawed or lightly flawed emeralds are difficult to find and very expensive when they are found. So it was only natural that someone would try to do better than Mother Nature. In the 1930s, Carroll Chatham succeeded. Other growers soon followed.
As they grow in the earth, emeralds are subject to temperature changes, intense pressures, and impinging hot liquids that can burn, melt, crush, or corrode the stones. Violent mining methods don’t help. As a result, many mined emeralds come from the ground with a number of inclusions and fractures that can not only dull the beauty of the stones, they can weaken the stones as well. In fact, emeralds can be notoriously difficult to cut and set if they are badly included.
