Real or false stones, how to recognize them?
How to recognize a real stone from a fake one? Tricks are often used for jewelry that can
deceive those who are not experts.
Beware of fake stones. But also to those who are half-fake. You may not know that there are
many ways to simulate precious stones on jewelry, and there are many ways to make a Red
Gemstones more interesting than it is. Of course, the greatest danger is when buying a jewel
without the usual guarantees and certification of a gemological institute. Or some suspicion
may arise for some old family jewel, whose origin is unknown.
Fake stones
Plastic and glass are materials often used to simulate lab made gemstones. Technology today
allows you to create something in the laboratory that cannot be distinguished from natural
stones, such as rubies, emeralds, or fossil resins such as amber.
Of course, an expert jeweler or a specialized laboratory can identify if they are fake
gemstones or imitations. If you have any doubts, ask for specialist advice.
Artificial stones
Cubic zirconia and synthetic moissanite (there is also the natural one, rather rare) are two of
the lab grown gems and which have characteristics similar to authentic gems, such as
diamonds. Similar, but not the same. Of course, if you want to sell them, they have a little
value, but at the time of purchase, only a gemologist can distinguish cubic zirconia, often
passed through a zircon, which is instead a natural stone.
Composite stones
One of the trends among jewelers is the proposal of half-true Emerald Gemstone and half
composed of other materials or other less expensive stones. The goal is to make the stones
used on the surface appear more substantial, adding an imitation, perhaps in the lower part of
the stone, hidden by the setting. This system is less frequent for transparent stones, while it is
more easily used in opaque ones, such as opals or turquoise.
Sometimes the lab grown gemstones are just a small layer that is glued onto a less valuable
mineral. Another system, however, concerns transparent stones. To get an exciting shade, an
expedient consists of gluing two or three different stones with a special invisible adhesive to
make them look like one and transform it into a "precious" Emerald Gem with a fascinating
shade. In addition to relying on a brand that enjoys your trust, it is good to carefully observe,
perhaps with a lens, the workmanship of the jewel.
Fantasy stones
Another idea of those who do not want to be transparent with those who buy jewelry is to
change the name of the stones. If you read that a ring has a synthetic emerald, for example,
know that it is a green sapphire, which is less valuable. Other examples: an "American ruby"
is a garnet, which is worth much, much less. And the "Australian jade"? It is simply treated
quartz. Reconstituted stones
Some stones are stabilized or rebuilt. Often it happens with turquoise. Stabilization consists
in subjecting the stone to pressure to make it more compact and eliminate the chalky
consistency. Also, Alexandrite Stone or other soft stones are often reconstituted by mixing
the powder with a binding element. In short, they are a kind of pasta, to which colorant is
often added to make the color more vivid.
