Is gelatinous or natural tourmaline?

With the fiery heat of the crystal market, the interior of various crystals has gradually become clear and transparent, and “Crystal Injection” has become the primary problem for crystal beginners and crystal lovers in choosing crystals! As the leader of semi-precious stones in recent years, tourmaline has long been the hottest topic in the market. Many tourmaline beginners and enthusiasts have been consulting some questions about the injection of tourmaline. Today, some questions about the injection of tourmaline are unified to give you an answer.

First, why is the tourmaline to be glued?

This problem is a question that beginners who do not understand the nature of the tourmaline and the processing process will raise. We know that tourmaline is a borosilicate mineral body, which displays a colorful color according to the difference of trace coloring elements, so it has the reputation of “the rainbow that falls into the world”.

So why does tourmaline need glue? From the physicochemical properties of tourmalines, it is not difficult to see that the tourmaline has a relatively high hardness and the crystal is brittle, so it is easily broken and brittle during the cutting process! Therefore, the initial motive of the injection of tourmaline is actually to facilitate the processing of the finished product of tourmaline. The madness of the online injection of plastic injection is only a side effect derived from later. In order to avoid cracking of raw materials and increase the yield, many tourmaline processing plants fill the glue before cutting. The function is to increase the adhesion and increase the transparency.

According to statistics, even if the tourmaline has a production rate of only 10-20%, if it is not filled, the yield will not exceed 5%. This is one of the main reasons why the price of tourmaline is high. Therefore, in order to reduce the cost and increase the yield, most of the tourmalines will be filled before the cutting.

Second, which tourmalines will be glued?

Are all the tourmalines glued? In fact, it is not the case that the tourmaline injection occurs in the tourmaline with more cracks, that is, the tourmaline with more cracks and cotton batt is usually processed by injection molding! This kind of tourmaline has poor permeability and coarse texture due to its internal ice cracks. Therefore, it must be improved by the injection molding method to improve its yield and permeability, and also to cover some cracks and impurities! Then the vitreous of the vitreous must not be glued? This is mainly based on the rigidity of the vitreous tourmaline and the skill of the processing master. That is to say, not all of the vitreous of the vitreous is glued, but the vitrified one must be the vitreous tourmaline!

Third, how to identify the injection of tourmaline?

This question is the one that the consultant listens the most and the one that answers the most! As mentioned above, the general injection of tourmaline is mainly concentrated on the tourmaline with poor appearance and more cracked ice, and the best vitreous tourmaline ring bead is basically not glued! Injection molding affects the cost of the sale, the factory is not a fool! So how to identify the injection of tourmaline for the poor quality of the tourmaline? The most direct is the machine to do the identification! The general identification certificate of the injection of tourmaline will write: "Natural inclusions, with fillers inside!" This refers to the natural formation of ice cotton and cracks in the natural crystal; the inside of the filler, refers to some of the gum left in the process of polishing and polishing. Secondly, the naked eye can also be distinguished! The surface of the gelatinized tourmaline has a spider web etch at the time of magnification observation, and the gloss of the gelatinized tourmaline is not strong enough, the interior is not clear enough, and there is a mixed feeling of colloidal!

4. Is the injection of tourmaline or natural tourmaline?

As early as a few years ago, the color of crystals and crystals changed over time in the long-term erosion of sun exposure or domestic water, and nowadays, with the improvement of processing techniques, such things will definitely not happen again. ! I said before, the tourmaline injection is only to improve its yield, and the improvement of color tone and transparency is only a secondary effect. Injection molding does not change the internal structure of natural crystal. Therefore, the injection of tourmaline is still natural tourmaline, because of this type. The price of tourmaline is low and the appearance is poor. Injection molding is only a necessary processing procedure! Of course, this is based on the needs of different people!
