How to identify gemstones
If you are a collector of gemstones and read about them or even do not care about this field, it has often crossed your mind while you were wandering on the beach or while you were going camping in the desert, whether there is a gemstone among those huge quantities of precious stones. Stones and rocks scattered as far as the eye can see, especially if you see one of the stones with a distinctive appearance that suggests that they are of valuable value. We invite you to read the following lines so that you can quickly identify most of the gemstones by noting some of the basic properties of the stone; For example: color and weight. Here, we will learn together about some steps to help us understand how to identify gemstones easily.
First: How to verify any stone as being a gemstone
Feel the surface of the stone, if the surface of the stone is rough or sandy It is not a gemstone.Checking the malleability of stone: Stones that are easily malleable in the sense that they can be formed by several things such as hammering, crushing, or bending it, then this stone is more likely to be a rough mineral than a true gemstone.Real gemstones have a crystalline structure and this structure can be formed by cutting, breaking and scraping, but it has fixed levels and layers that cannot be changed through pressure only.
Various gemstones
Learn about the materials that cannot be classified as precious stones: in particular, pearls Pearl and petrified wood as they may be misclassified as gemstones but do not correspond to gemstone efficiency in the literal sense of the word. Synthetic materials: Synthetic stones share with their natural gemstone counterparts the same structure, chemical composition and physical properties, but these synthetic stones are made in laboratories, unlike other naturally made gemstones.
Synthetic stones can usually be detected by several properties such as:
One of these characteristics is the stone growth patterns, where this growth is often a curvature within the stone rather than an angular growth.
Platinum or gold flakes can stick to artificial stones.
Beware of imitations: Imitation stone is a material that looks like real gemstones at first sight although it is made of completely different materials, these stones can be natural or synthetic But there are good techniques that are used to find them anyway. Pay particular attention when examining turquoise, lapis lazuli, sapphire, ruby and emerald as there are many treatments available on the market that make these stones look the same as natural stones.The surface of a traditional stone may look pitted and uneven like an orange peel
Some traditional stones have markings known as “flow lines.”
Large and full gas bubbles are common in traditional stones.
These stones tend to be lighter in terms of weight than their natural counterparts.
Determining whether a stone is assembled or not: Those stones that are It is assembled from two or more materials. These stones may consist entirely of natural gemstones, but are often mixed with synthetic materials.
Use the light pen to clarify the stone when examining the stone for signs of assembly.
Look for differences in the luster of colored or colorless stone or cement.
Also look for the “Red Ring Effect”, turn the stone down and find the red ring along the outside of the stone. And if you notice that ring, know that it is most likely an aggregate stone.

Distinctive properties of precious stones
CHECK COLOR : The color of the gemstone is often the first clue when examined; This element can be divided into three parts, which are the hue, the degree of color and its purity.
It is worth noting; That the stone should not be highlighted when examining it except in the case of examining dark-colored stones and you need to determine whether the color is black, dark blue, or any other dark color. Hue: Refers to the general body color of the stone and this color is as specific as possible. For example, but not limited to, if the color of the stone is yellowish-green, it is better to identify it with those colors in this way rather than identifying it with red, since the color gradation has been divided into thirty-one different colors.
Tone: Indicates whether the color is dark, medium, light, or somewhere in between.As for the purity of the color, it refers to the intensity of the color2016 Check the transparency of the stone : The degree of transparency of the stone can vary as it can be It is completely transparent, semi-transparent or opaque. Diamonds are transparent stones, while amethysts and sapphires are semi-transparent stones, and opals are an example of opaque stones.
start=”3″>and its estimated specific weight: You can determine the weight of the stone simply by holding the stone with your hands, and this is an easy and fast way to estimate the weight of the stone without performing specific weight tests and complex equations.
To determine the weight of the stone, place it in your palms and ask yourself if you feel the weight of the stone as expected given its size or if you feel particularly heavier or lighter.
Take note of the stone’s form in terms of its dimensions: Because the approach is not infallible for identifying the stone, some gemstones are more likely to be cut in more than one way.
