About the Opals The opals used in our Israeli jewelry are lab made opals. In the lab they make the opal the same way that it is made in the earth except they speed the process up - by a lot. The lab ones are almost as hard as the real ones so they should last about the same.

Lab Grown or Lab Created Opal These terms generally refer to polymer-impregnated opals, which are 70-90% silica (from which natural opal is formed) and 10-30% resin. Lab created opals exhibit fire play resembling the finest opal at a small fraction of the cost. The fact is they are all manufactured by man under laboratory conditions. This shouldn’t be a surprise as other gemstones such as sapphire and emerald to name just two, have been manufactured in laboratories for years. Most created gemstones contain the common elements that occur in natural gemstones and this applies to Synthetic opal. One common element missing in synthetic opal however, is water. This is in fact a bonus to the synthetic opal as the absence of water makes the synthetic opal much more durable and harder than the natural occurring opal. The first person to create opal was a Frenchman by the name of Pierre Gilson and he did so in 1974. Gilson opal is still a name widely recognized as being created opal. Since then there have been other methods introduced. One is to add a polymer substance (glue) which helps bind the silica spheres which make up opal. So what usually takes millions of years in nature to create can now be done over a number of months in a laboratory. Synthetic opal jewelry is an excellent alternative to natural opal jewelry for a number of reasons. The first to spring to mind is the beautiful array of colors and patterns that are displayed in very rare natural opal are readily available in created opal. The synthetic opal is much more durable and harder than its natural counterpart so breakages and longevity are also a plus.
