What is Gilson Opal?
In the early 1970s, Pierre Gilson invented a technique for producing opals in the laboratory. Today, the Gilson method is still thought of as the most genuine gemmological process available.
These types of gemstone are created in controlled laboratory conditions similar to what might be found in nature. The colours are natural and a harvest is now possible in 18 months.
They have virtually identical chemical composition, physical and optical properties to that of the natural opal.
The exception is that the laboratory grown opal is harder and more durable than its natural counterpart. This hotsell is because, unlike natural opal, it does not contain water.
