14K Gold Gilson Created Opal Pendant. Measures approx. 1-3/4" L. 18.2 Grams Total Weight. The laboratory opal producing process was first invented by Pierre Gilson, Sr. of France in 1974. This process produces a kaleidoscope of colors. From the rare and precious black opal, to crystal and white opaque opal. The Gibson formula is considered the truest gemological process in the world today. Considered by many gemologists to be the world's finest laboratory grown opal. The process takes from 14 to 18 months, and the colors are natural with no treatment or enhancements. Unlike its natural counterpart, this created opal is much tougher and not prone to breaking. It gets its hardness because it contains no water. Unlike natural opal which does contain water. The lack of water in Gilson opal has currently brought about debates and differences of opinion. Natural Black Opal is exceedingly rare and expensive. These stones, whether they are finally classed as Imitation or Synthetic are the best mimic to real opal we have seen.
