For most of the opal stones lovers, telling between real and fake opal jewelry is an uphill task. The obvious sign of fake opal jewelry is that it can be easily differentiated with the real opal when closely examined under magnification. The pattern of coloration on natural opal as seen is arranged in a lizard or chicken wire format. The fake opal stone on the other hand does not fluoresce under ultraviolet light; they are basically lower in density and obviously very porous. As well as natural opal, all types can be synthesized for experimental and commercial reasons. This discovery of the ordered sphere structure of the precious opal gemstones led to its synthesis by one Pierre Gilson in the early 70s. Internationally, there are two well known producers of fake opal. Both of them are found in Japan.
It’s vital to note though that most of the so-called fake opal gemstones are more correctly termed copies, they have within them materials not found in natural opal a good example being the plastic stabilizers. Fake ones seen in vintage jewelry are often foiled glass, glass-based Slocum stone- silicate glass showing traces of sodium, magnesium, aluminum and titanium. or later plastic materials.
The so called fake opal gemstones not necessarily fake because some types are chemically same with the forming varieties. Others artificial gemstone opal types have an inclusion of both natural opal and other materials. On the other hand the fake opals are chemically and structurally look like natural opals gemstone, but these are made in the lab, not in the mine ground. These should never be confused with natural opals stones. The main differences between them are their color patterns, which are commonly more regular and exact. Also fake opal appears glassier than natural ones and is still considered to be real opals in some quarters.
Fake opal price is generally very low since they can be produced in large numbers at once while the natural opal is costly due to the fact that they are mined below the ground and take millions of years to form. The fake opals are actually made to resemble the natural opal. They are basically made from such materials as; glass, synthetic opal, or plastic. It’s vital to note that some plastics that have plastic binders are also called a synthetic opal which is very correct.
The fake opal can still make beautiful jewelry. They are not the natural opals, but there is nothing fake about the beauty of a well-made fake opal, and when it comes to jewelry, its beauty is really the whole point. But for those who love the natural beauty of the opal gemstone, then close observation of these stones would reveal to them whether they are natural opal or fake ones. It would be essential for them to have a scrutiny of the opal jewelry if they have any suspicious. Always make sure that you ask the jeweler queries as far as the suspicion opal is concerned. You might find the price to be quite too low than expected. This should make you do more research and clearly look for clues above to give a determination of whether the piece of jewel is natural opal or a fake one.
