It is called that way various hard minerals, transparent, very valuable for their rarity and that, after having been conveniently carved, are used in jewelry and decorative arts. Topaz Gemstone are manufactured to mimic other gems. The imitations copy the shape and color of the stone but do not have their physical or chemical characteristics. There is an ongoing Sapphire Sale here. Small artificial diamonds have been mass-produced for several years, although only recently have great quality diamonds been created, especially colored ones.
What are natural gems, treated, synthetic and imitations?
These terms come to define the way we have to find a Tanzanite Loose Stones; we can buy it loose, we may have bought it already assembled in a jewel, it can even come from a long time ago from an old piece; We will always have the certainty that this gem may be any of the possibilities I mentioned before.
Natural gem: It's very clear! No? Any mineral crystallized naturally without mediating at all the hand of man, except in its extraction.
Gem treated: Here the mess starts a bit; by definition, it is any treatment that is given to a natural gem to improve the characteristics that give it beauty, usually color and transparency. However, here comes a nuance that is what makes it more complicated ... there are some treatments allowed and others not; These differences are "legalized" by the international organisms of gemology and jewelery. The difference between one and another supposes the "obligation" of the seller to say it or not. For example, a Red Star Sapphire treated by heating will be allowed and in fact practically all of the gems are treated as of origin, however that same sapphire treated by diffusion. It will be considered a gem of much lower value and the seller must market it as sapphire dissemination and explain the origin of that name. Of course in the end everything is based on the price of the Garnet Gemstone; and one should not be considered cheated if the price of the gem really corresponds to the material sold, although ethically the seller must always say it, it should be noted following the previous example that a sapphire diffusion should cost around 4-5 times less than a sapphire heated, both come from natural corundums but one of them is "accepted" and the other is not.
Synthetic gem: It is the gem that with the same chemical characteristics as the natural one has been created in the laboratory.
Gem of imitation: Here the three previous coexist basically; imitation stones can be any stone that by its physical properties can be exchanged with another because it resembles a gem of a much higher value. The best known example is that of the Zirconia (synthetic gem) which the most common imitation of the diamond is.
For those who want to know more exhaustively all the possibilities of each definition there are the treaties of gemology in which you can see virtually all types of gems, Gemstones For Each Month, their treatments, their synthesis and which gem can imitate another, it should be noted that as a science of the nature that is, is in continuous development and research and many new developments arise every year.
