The physical and chemical properties of minerals such as hardness, fracture, line, optical properties, texture, structure of rocks and their chemical composition are taken as basic criteria that are applied for their classification. Another aspect of great importance in the recognition of minerals and especially semiprecious stones is the ability of observation, ingenuity and skill of the teacher, which is achieved only with practical work, perseverance and love for semiprecious stones. In the wide group of “gems” or “gemological materials” are included all natural or artificial materials, mainly of mineral origin, but also animal, vegetable, meteorite, etc. which are used for ornamentation and personal adornment.

There seems to be a tendency, which manifests itself in all cultures, even in the most primitive ones, for men and women to use the most striking objects, and also the scarcest, that nature puts at their disposal as personal adornment. This blog has been linked with personal vanity, with the testimony of power or singularity of the one who carries the valuable object, and also with supposed magical or supernatural powers. It is known that primitive man used, recognized and was able to carve up to 15 different types of “gems”, among which are bone, various shells , amber , jet and some natural glass . The existence of some of these materials in points very far from their place of origin allows affirming mobility and commercial channels in the Neolithic that could not be suspected if these vestiges did not exist.
For example, the existence of amber from the Baltic Sea in Mediterranean Neolithic cultures, or the presence of lapis lazuli from Afghanistan in the cultures of the Nile valley, which were supposed to be relatively closed to external influences.
The purity corresponds to the type of precious stone
Type I: these are gems that must be completely transparent to the eye at a distance of 15 cm. Never buy an amethyst or topaz with inclusions, blemishes or cracks inside! In this category are – among others – gems such as Topaz, Aquamarine, Amethyst, Morganite etc.

Type II: These gems have some visible inclusions. And it is practically impossible to find them absent of inclusions, and in case of finding them they behave the exception and acquire astronomical prices. To this type II belong and the Rubies. The more pure and transparent is a Ruby, the more its value will increase, but in any case small inclusions will be found inside it. If these gems tend to be opaque they will lose in value. Very often it happens to find unscrupulous sellers that offer jewels with completely opaque Rubies and Sapphires at high prices under the pretext that they are true Rubies and Sapphires. Do not be fooled and look for your jewels with transparent and brilliant precious stones. Check out more at blog.
Type III : there are gems with well marked inclusions. Emerald is the best example with its well-known “garden”. Let us not be wrong then when evaluating an Esmeralda, whose value does not diminish because of its inclusions, as long as these do not undermine its beauty. On the contrary, Esmeraldas with inclusions is the norm and in many cases these inclusions increase the beauty of the gem forming beautiful gardens inside. At the same time if you find an Emerald of few inclusions and of beautiful color its price will go to the clouds in a flash.
Know the origin of the precious stone
To choose well a gem know its origin. Certain precious stones reach great value if they come from certain regions of the world. Think, for example, of the Sapphires of Kashmir, the Rubies of Burma (Myanmar), the Emeralds of Colombia, the Amethyst of Uruguay and the Paramalba Tourmaline of Brazil, just to mention some examples.
The Precious Stones are natural geological formations that have been formed in precise places where particular geological phenomena have taken place. These phenomena are responsible for the special formation of Precious Stones, giving them characteristics that differentiate them from their sisters in other localities. The Amethysts of Uruguay, for example, have an iron content and a particular degree of oxidation of this metal that is different from the rest of Amethysts found in other parts of the world and for this reason its coloration is unique. It is the geological phenomenon that has allowed the formation of this wonder in a place and in a very specific environment.
But also in this argument one must be careful and be attentive. You should not choose a precious stone just for its place of origin! In all deposits are good and bad quality gems. An Esmeralda from Colombia is not going to be better than another just to carry the denomination of origin: “Colombia.” They have been in Zambia for some years, emarald of such quality that they are capable of competing with the famous South Americans. Buy exclusively jewelry with authenticity certificate! As in all fields where large amounts of money are at stake, there are counterfeiters and sellers who live by taking advantage of the buyer’s lack of knowledge or naivety. Have a look at the blog.
One of the most common choices when it comes to carrying a stone for its special meaning is the ring. When the rings incorporate the birthstone or the month of birth, it is a very comfortable way to carry your birthstone with you. But if you are more than bracelets, there are also charms that include the birthstone of the month of birth, such as filigree hearts in sterling silver with the gem of each month set. Above all, a certificate of authenticity guarantees that the precious stone is not artificial and is not the output of a laboratory.
In addition the certificate will guarantee the site of its extraction and will give you the necessary information for an eventual assurance and / or expertise, as well as its carat weight, the type of size of the gem and its dimensions. See the blog.
