Garnet and tourmaline belong to the series of colored gemstones, and the colors are more. The most confusing ones on the market today are red garnet and red tourmaline. These two gems are very similar in color. If you don't know much about gems, then it is difficult for you to distinguish them by the naked eye. But it doesn't matter, let me introduce the difference between garnet and tourmaline, I hope to help you.
One of the differences between garnet and tourmaline: physical properties
Garnet is a silicate mineral and the color varies from species to species. The most common are magnesium-aluminum garnet, which is mostly red, purple and maroon. The second is that the garnet and magnesia are mostly purple and light rose, and the rare calcium garnet is green. The garnet has a hardness of 7-8 and a density of 3.5-4.3 g/cm3.
Tourmaline belongs to tourmaline, and there are many colors. But unlike garnet, it will exhibit pleochroism, that is, multiple colors inside and outside the same crystal or in different parts. Its hardness is similar to that of garnet, which is basically 7-8. The density of tourmaline is about 3.06g/cm3, which means that the two gems of the same specification will be heavier.
If you carry a magnifying glass with you, you can find that there are gas-liquid inclusions, irregular tubular inclusions and parallel linear inclusions in the tourmaline crystal, which are not available in garnet.
The difference between garnet and tourmaline: look at the luster
Because there is a lot of crystals inside the tourmaline, when viewed from the outside, the crystal will reflect many beautiful small bright spots, the surface will show glass luster, and a few will present cat-eye structure. The garnet color is relatively uniform and thick, and the internal crystallization is relatively stable. Therefore, from the surface, the color of the garnet is dark, unlike the tourmaline, which has no aura, and its gloss is not as good as the tourmaline.
The difference between garnet and tourmaline: adsorption
The biggest difference between tourmaline and other gemstones is its piezoelectricity and pyroelectricity. After friction and heat, tourmaline will produce strong adsorption, which can absorb paper dust and hair, and garnet has no such characteristics. This is the simplest and straightforward way to identify garnets and tourmalines.
In addition, in terms of efficacy and function, there is a certain difference between the two. For a detailed description, we can look at the efficacy of tourmaline and the efficacy and function of garnet. If it is from the price point of view, the price of tourmaline is higher than that of garnet, so some unscrupulous merchants on the market will take garnet instead of tourmaline sales, so we should pay attention to distinguish when buying.
