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.

Jewelry is a world market; people around the world like to wear garments made with great beauty and detail and adorned with a gem that completes the work. Although the semi-precious stones are many, there is a part of them that is the most frequently used in this company.
Amethyst
The amethyst is one of the most versatile gems in jewelry, the most commonly used because it has a particular beauty and brightness almost similar to that of the diamond.
Its color varies from pale browns to violet and blue tones through reddish colors. However, one of its peculiarities in the area of jewelry is that the topaz can modify its color through artificial procedures, specifically by subjecting the mineral to gamma rays of different frequencies. For certain periods, it allows giving the topaz almost any desired color.
ITS transparency and brilliance have been confused many times with birthstones by month the Portuguese crown had this stone embedded in it, which was later confirmed to be a topaz.
Moissanite
The moissanite is a special stone among many stones classified as semi-precious, and one of the things that makes them most valuable is the beauty of its colors, especially the red ones. Its beauty, at first glance, is capable of surpassing even that of precious stones such as ruby.
It is only under ultraviolet light and other scientific procedures that the difference between citrine and spinel can be seen. This stone is widely used and highly valued in jewelry, garments made with this stone are usually very valuable, however within the range of what is accessible to the public.
Alexandrite
The alexandrite is a stone with many varieties. However, the most valued in jewelry is noble opal, a kind of opal characterized by the different colors that can be seen in it, very intense colors in the form of lamellae within the gem that can be seen while the opal is moving.
The tourmaline has a captivating beauty, beyond the fact that they are not as shiny or crystalline as other gems, their use was also frequently established for the jewelry of royalty and important personalities of the Middle Ages.
This mineral also has mysticism, which relates it to deities and to spiritual and healing powers that make it even more special.
The birthstone colors, for example, is one of the most valuable, both for its beauty and rarity and for what it represents; some acquire jewelry with opals as a kind of talisman or amulet.
Aquamarine
This stone has a particular beauty associated with its color and crystallinity. These characteristics are what mainly makes them valuable in the world of jewelry. Some of the garnet gems, after being polished and worked, have such a beauty that it has come to be compared to the emerald.
The Pearl
The pearl is a different gem from the others, and this is because its origin, unlike most, is not due to geological processes that involve high temperatures or extreme pressures; but it has an animal origin.
Pearls have been used since ancient times for the manufacture of jewelry, more specifically to create pearl necklaces, which came to be widely used by women who were part of the world's royal families, aristocrats of the time. Tanzanite necklaces are highly valued and expensive in jewelry, to the point that they are not accessible to all social strata.

What are the characteristics that a precious stone must have to define itself as quality? In reality, man has attempted to imitate natural stones since ancient times.
Synthetic material can be abridged in these three types:
- colored monocle;
- Compound materials;
- Artificial stones;
Both the use of colored glass and composite materials are not recent discoveries. The first productions date back to Roman times.
Artificial gemstones have physical characteristics different from the imitated natural materials and therefore allow easy recognition. The "braces, triplets represent the composite material."
The last challenge, synthetic products
Imitated stones are the newest product of man and are not a sensible replication. With the synthesis process in the laboratory, it is possible to produce rubies, sapphires, emeralds, loose gemstone, and anything else having the same physical and chemical characteristics as natural ones.
Sometimes these processes are very expensive and limit their production as happens for the synthetic diamond for which it is preferred to use similar synthetic gemstones but not existing in nature such as YAG, GGG, cubic zirconia, and synthetic moissanite.
Some compare these products to vitamins, and there are natural ones (which of course cost more) and non-natural ones produced in the laboratory.
Artificial vitamins and synthetic stone have a similar chemical arrangement as their corresponding natural item. Therefore they cannot be defined as simple "imitations."
Synthetic products are complicated to recognize, but they differ from the natural ones!
There is a difference between the mother nature product that has spent millions of years producing a crystal, and that originated in a few weeks by man.
The first products were more easily recognizable, but nowadays, we must make them think of their perfection or the production of stones too beautiful to be exact!
Inclusions and fractures are not always negative:
Some natural resources are normally incorporated and cracked. Inclusion of a tiny crystal, e.g., in ruby, can point to both its source and its birth. The total absence of enclosure should create us believe above all if we are assessing materials that in the environment are usually included, such as emeralds and rubies.
Attention to detail:
The shape, the type of cut, and the care in the polishing of the artificial gems are other elements that can suggest us to be in front of a synthetic.
Large stones, for example, emerald, are hardly available in brilliant round cuts. The same is true for other stones that are commonly cut with oval or mixed cuts. Often the cutter modifies the classic cut to recover more material from the raw stone and enhance its color, and this causes an asymmetry in the cut.
The price:
Generally, the synthetic stones are sold at very attractive prices, and the stones certainly present themselves very well, but pay attention to the deal! Therefore we have to buy loose gemstones.
No test is worth the word "natural" on a gemological certificate:
The tests that a gemologist must do to distinguish a natural stone from a synthetic one are many because often one is not enough to distinguish them. It is for this reason that a precious gemstones supplier prefers the stone with a microscopic inclusion over the pure one since that small inclusion is considered the clue and irrefutable proof of the naturalness of the stone.

Jewelry has always been one of the best gifts to give or receive. They can be adapted to every occasion, from birthdays to anniversaries, you can be sure that the receiver will enjoy what he has given them. Women love receiving the jewelry. From rings to necklaces, jewelry has always been perceived as a very personal gift, usually to show some affection towards the other person. Buying jewelry is one thing, but how do you select the correct moonstone color?
The first thing to consider is skin tone. There are two types of skin tones, warm and cold. To find out if someone has warm skin, their veins tend to appear green. A person with a cold skin tone will have veins that look blue.
Warm skin tone:
If the skin tone is warm, then you should look for oranges, yellows, and green peridot. For oranges, you'll want to look at fire opals or orange sapphires. For yellows, you'll want to look at citrines and gold pearls. For greens, look at peridots and emeralds.
Cool skin tone:
If, on the other hand, the skin tone is cool, then you should look at the bright red, blue, and purple aquamarine jewelry. For red, look to get ruby or garnet. For blue, look for tanzanite or topaz. For purple, look for amethyst and tanzanite.
Another thing to consider is the color of the eyes. Choosing a gemstone that matches your eyes can bring them out, although the contrasting colors can be just as good.
- Green eyes have a wide variety of gems that adapt. You can choose between jade, emerald, peridot, and zircon. Or if you want something exciting, go for a contrasting turquoise gemstone.
- Brown eyes adapt to diamond white. Red stones come in a wide range of shades and tones. Red gemstones include spinel, tourmaline, ruby, and garnet. Or if you want to go to contrast, try the blue gemstones.
- Blue eyes, as you can guess, adapt to spinel gem. But one thing to remember is to try to match the eye color tone with the gemstone. For good contrast, go for pink gemstones like spinel.
- The brown eyes contrast incredibly with the white sapphire. With so many shades to choose from, you can expect to find one that suits you.
Although the physical appearance of jewelry is important, some health professionals believe that the color of the birthstones is associated with different beneficial health properties. Some also believe that a certain color will give them good luck and fortune. Even the month of birth can be related to stone color.
So when it comes to choosing the right star sapphire, you should carefully consider the person's natural appearance. However, if you want to dig a little deeper, buy the birth month gemstone or your favorite color, this will show you how much you know them. It is very easy to buy jewelry online, so be sure to take a look at the stone colors in the shop windows before deciding to order online. If you are concerned about buying the wrong one, there are plenty of online jewelry stores that offer cheap gemstone jewelry.

Gems are undoubtedly a few of the best and also most attractive prizes our wonderful Earth has provided us. Many individuals buy loose gemstones, but few recognize just how vital it is to have a little knowledge of what to try to find when buying. With so many various types of rocks to select from, like emeralds, sapphires, or even newly prominent rocks such as tanzanite loosened gems, it is extremely vital to do some research study prior to you jump in as well as buy.
Check The Quality Of Loose Gemstones
Before you establish foot right into a store to purchase gems, you need to understand about the 4 C's: color, clarity, cut, and carat weight. You need to know, what they imply, and just how to evaluate a stone using the 4 C's. Certainly, we all understand that typically speaking, the bigger the rock, a lot more we will certainly pay. Not only the 4 C’s, there are a lot more things that need to consider. Excellent quality and small stones like carnelian will generally be better in the long run than a huge, reduced top quality rock.
When rating all-natural loose gems, shade is usually thought-about to be the most crucial variable. They must not be silenced or "thinned down looking". They need to be brilliant as well as vivid, with a tool tone that is saturated with shade. Always examine the shade of gemstones in varying types of light. They will look different in the daytime than in the bright shop illumination. The following crucial rating aspect for colored treasures is clearness. It is extremely unusual to find a natural stone that does not have any type of imperfections or incorporations in them. The fewer they have, and particularly if they are not visible to the nude eye, the better the rock will be. The cut of a gemstone is also really essential to think about because a stone that has not been reduced effectively will tend to look darker because it isn't showing significantly light. Carat weight is the way the gemstone dimension is measured. Remember, a 1/2 carat weight diamond will certainly not be the very same dimension as one-carat emerald green or a one-carat aquamarine loose stone.
Be Selective While Choosing Your Loose Gemstone Dealer!
Make sure to ask a lot of questions about the gem before purchasing it, and if your gemstone dealer is not able to answer those basic questions, or deny showing the certificate of the gemstone, then never ever purchase from that store. Make sure that you certainly get premium quality, valuable gemstone when you go shopping. Understanding the concepts of 4 C’s will help you a lot to get the best and top quality of loose gemstones at reasonable prices.
