What is Synthetic Opal/Lab-Grown Impregnated Synthetic Opal?
Among all man-made opal, lab-grown impregnated synthetic opal has the highest quality and value. It takes about a year to grow in the laboratory and is similar in properties to natural opal. Natural opal is composed of silica and water while impregnated synthetic opal contains a high percentage of silica, at least 80%. It also has the unique feature of vertical growth pattern. Lab-grown impregnated synthetic opal is a beautiful stone with perfect color vibrancy - revealing the beauty of precious opal
Other research in macroporous structures have yielded highly ordered materials that have similar optical properties to opals and have been used in cosmetics.
Synthetic opals usually display a very distinctive snakeskin pattern and they show brighter colors than natural opals. The spots of color are larger but they interact with light in a very similar way to natural opals. They contain 80% of silica which is impregnated with resin. Impregnated synthetic opals look good and appeal to some but can't replace what Mother Nature creates。
Synthetic solid opal can be very difficult to identify, unless you are an expert, or have a lot of experience. Look closely at the pattern - Opal created in a laboratory (Gilson opal), displays bright colors in large patches of color. The pattern is often 'too perfect' and ordered, and can also often display a 'snakeskin' pattern. If you are still not sure, take it to a gemmologist or an opal expert.
