The Gilson created opal was invented by Pierre Gilson of France in 1974 and is considered by many gemologists to be the world’s finest laboratory grown opal. The growth process takes from 14 to 18 months, and the colors are natural with no treatment or enhancements. Its unique properties and brilliance set Gilson opal apart from all other man-made opal. Unlike natural opal which contains 3 to 21% water, Gilson opal contains no water. Gilson created opal is much tougher than natural opal and is not prone to breaking or cracking.  See blog
