Gemstone identification can be tricky. Especially if you are
a novice in this area, you will have a hard time figuring out what gemstone you
are looking at without relying on some help.
However, if you are really passionate about your gemstones
then there are ways that you can learn to identify gemstones. It will take a
lot of practice and some serious mental training, and the truth is that with so
many different gemstones out there, the learning process never really ends.
So how is it that some people learn how to identify
gemstones just by looking at them?

The Process of Gemstone
Identification
If you’ve ever tried to identify gemstones or even looked at
someone trying to identify them, you are probably already aware that
identifying gems is a process of finding clues and eliminating all
impossibilities, until you are left with a very short list of possibilities, or
in an ideal situation, only one possibility.
For instance, all rubies are red in color, but not all the
red gems in the world are rubies. So while having a keen eye for the physical
properties of the gem, you also need to have very good knowledge on the subject
to be able to identify what kind of gemstone you are looking at.
A lot can be told about a gemstone just by looking at it for
the first time if your gaze is careful. You don’t really require any fancy
tools to analyze the stone; all you need is some light that will help you
properly examine the gem.
To narrow your list down to a few possible gemstones, you
will have to analyze the different aspects of the gem including the color, hue,
tone, saturation, clarity, transparency, opacity, luster as well as the shape
and size.
Here’s what to look at:
·
Color
The easiest way to shortlist the list of possible gems is
just by looking at its color. Simply looking at it will get you more than
halfway there. For instance, if a gemstone is green, it can’t be a ruby or an
amethyst, apatite, a sunstone etc. It can, however, be an emerald, green
sapphire, tourmaline, jade etc. So once you’ve narrowed it down, you have
eliminated a lot of possibilities.
The problem however is that, although this is the most
effective step, it is also the easiest one; the “suspect pool” you now have
would be a lot more difficult to work with, since now you have a slot of
similar looking gemstones in there that will be hard to eliminate.
·
Hue
As already stated above, determining through the color is
the easy part. The next thing you have to look at is the hue. Going by the same
example as before; if you have a green gemstone in front of you, is it more
bluish-green or is it yellowish-green? These things can help you make huge
progress. Like if it has more yellow in it, it could possibly be a peridot, but
if it has more blue, it could be green flurite. If it doesn’t have any shades
other than green, then it could be an emerald or a chrome tourmaline. So try to
be as precise as possible while figuring out the hue.
There are about 31 hues that you can match your gemstone
with in order to determine what kind it is. You can find GIA’s color wheel over
here
that will help you with this.
·
Tone
Now that you have determined the color and hue of your
gemstone, it is time to look at the tone. Is it a light, medium or dark colored
gem? You can further use the GIA color wheel to determine this, as according to
that chart, there are around 7 levels of tones. And if you determine the exact
tone, you have taken another step in the right direction.
·
Saturation
Just like tone, saturation is another thing that will help
you narrow down your list more. Look at your gemstone through a proper light
source. Determine how intense the saturation of its color is. Is it very vivid
or is it just flat? Remember that if a stone with a cold color has grey
undertones, it would be considered flat. Whereas a warm colored gemstone with
brown undertones would be considered flat.
·
Clarity
This one is a comparatively easy step. Take a good look at
the stone; is it more transparent, translucent or plain opaque? Can you see
through it? Can you look inside it? All of these things help determine what
kind of stone it is.
·
Weight
You can use a scale for this, but if you don’t have one
handy, you can also use your hand for it. Hold the gem in your palm and figure
out how heavy it or light it is. Is the weight proportionate to its size or do
you feel it’s fairly lighter or heavier than what you may have initially
expected? This may be a difficult process to learn, but it can definitely help
you eliminate a few possibilities from your “suspect pool”.
·
Luster
Finally, look at the luster of the gemstone; which means to
figure out how it shines. Set the stone down and shine a light on it. Is it
shining? Is it reflecting the light back or is it immersing it? There are different
kinds of shines that you can recognize. For example, vitreous (which is like a
glassy shine), silky, oily, waxy or adamantine (like diamonds). The gem may not
be shiny at all, which will also help you eliminate a lot of possibilities.
How to Identify When a
Stone Is NOT a Gemstone
Just like there are a lot of ways to recognize a gemstone,
there are a few ways you can discard it from being a gemstone at all. Here is
how to recognize when the stone you are looking at is not a gemstone at all.
·
Feel the Surface
A real gemstone always has a smooth or slippery texture. So
feel the surface to check whether it is sooth or not. If it is rough or has a
sandy texture, then it cannot be classified as a gemstone at all.
·
Check Its Malleability
A real gemstone has a crystalline structure. This makes it
difficult to shape the stone by bending, hammering or crushing it. Instead, it
needs proper fracturing, abrasion or even cutting to be shaped, as pressure
alone will not work on it.
So a stone that is more easily malleable is more likely a plastic,
or possibly metallic ore rather than an actual gemstone. However, do not try to
hit the gemstone with a hammer. You cannot shape a real gemstone with a hammer
but you can definitely crush it into a million pieces.
·
Check If the Stone Is an Assembled Stone
A real gemstone is entirely one piece. Whereas assembled
stones are made with two or more materials combined together. These stones are
usually made in labs and more often have synthetic materials mixed in them. These
can be difficult to tell apart from their natural counterparts.
Look through the stone against a strong light source to look
for any signs of assembly. Check if there is a difference of luster or if the
stone doesn’t feel consistent for some reason. Identify the “red ring” affect.
Place the stone on a surface and shine a penlight through it. If you see a red
ring effect around it, it is an assembled stone.

The Art of Gem
Identification
Ultimately, the final step of gem identification is the
point where it becomes an art. You can look at the color, hue and saturation to
eliminate stones, but finally, it will be your knowledge of gemstones that will
help you make your final determination about it, along with your experience and
observation. You can take precise measurements with proper instruments, but it
will only get you so far.
Especially when you have to separate natural gemstones from
synthetic ones, you have to trust your instinct and observation over everything
else. The optical properties and physical measurements of a synthetic gemstone
will be almost identical to its natural counterpart. Trying to differentiate
between these will require keen observation, sometimes through a microscope to
make proper judgment.
So ultimately, the final judgment depends on how much you
plan to study gemstones.
Invest in a Gemstone
Identification Chart
If gemstone collection and identification is something that
you are passionate about, then it would be a good idea to invest in a gemstone
identification chart. They are pretty affordable and can help you recognize a
variety of gems. As you constantly reference the chart for identifying gems,
you’ll eventually train your eyes to recognize stones by default.
Make sure that you buy a chart that is very comprehensive
and includes most of the common and not so common gemstones, so you can learn
about everything possible. Opting for a book by Gemological Institute of
America (GIA) is a good idea as their books are very detailed and accurate.
But if you just like to occasionally spend some fun time
trying to identify them, then a basic chart would do as well. Something that is
easier to understand and not too detailed will work for you a lot better than
one that is filled with information that you aren’t particularly interested in.
So pick your chart according to your needs. (using our links

Little Knowledge Is a
Dangerous Thing
If you were a complete gemology novice before clicking this
link, then chances are you’ve learnt a little something about the subject.
However, a little knowledge can indeed be a dangerous thing.
Gemstones are a precious material and can be very expensive.
So if you want to learn about gemology, you have to be a little more than a
novice to make your endeavor worthwhile. You do not want to make a rash
decision about a gemstone with limited knowledge as this could be very heavy on
your pockets.
You also need to be cautious about who you trust with
gemstone identification. Many of the jewelers don’t have as much experience
with colored stones as you may expect. Unless someone is trained in gemology,
they are more likely to make a decision based on their very limited knowledge.
Even people who have graduated in Gemology can come across stones that they
have never seen before.
So if you plan on buying or selling a gemstone, it is a good
idea to take multiple opinions about it, instead of accepting the first
possible answer.
Acquire Proper Knowledge
If you still believe that you want to learn more about the
subject of gem identification, then you can take classes and earn an actual
degree or certification in it. Gemology courses are offered at a lot of
colleges and universities. It is possible that this may be an expensive
decision that will require a lot of commitment, but if you are passionate about
it and think you can make it work, then it will definitely be a worthwhile experience.
If you don’t have that kind of time or money, you can also
opt for online courses that will help you get more than the basic ground
knowledge of gemology, that will help you chase your passion. For instance,
this site
offers one such course on Gemology. And the best part is that you can work at
your own pace if you take these classes. Want more ! Join our social sites below for video, downloads community, education, entertainment and more.
