How the difference between artificial ruby ​​and natural ruby ​​distinguishes true and false rubies
Ruby is the only gemstone with a hardness of 9 in red gemstone. The hardness of cubic zirconia is 8.5. It is a synthetic product. It only needs to scribe cubic zirconia with the edge of the ruby ​​to be tested. The runner is ruby, and the person who is not moved is not ruby. This method is applicable to the identification of gemstone raw materials and various ruby-type rubies. However, it belongs to the damage identification and is used with caution for faceted gemstones. Do not use the sharp edges of cubic zirconia to scribe the ruby ​​countertop, otherwise scratches will be left on the ruby. The difference between artificial ruby ​​and natural ruby The identification of rubies can be divided into two steps. The first step is to distinguish the real ruby ​​from the other red gemstone substitutes; the second step is to distinguish the natural rubies from the artificial rubies. Usually the more pure and rich the ruby ​​color, the higher the quality and the higher the value. After combining various factors affecting the color of red sapphire, we divided the red sapphire into five levels, including ruby, red, medium red, light red, and light red. Consumers can simply grade the ruby ​​color by simply comparing the five levels of ruby. Nowadays, the technology of artificially synthesizing ruby ​​is very mature, and there are many methods for artificially synthesizing ruby. However, there are currently three main methods: flame melting method, flux method, and hydrothermal method. Among them, the flame melting method ruby ​​is easier to identify, and it is determined to be synthetic ruby ​​by observing the internal curved growth lines and bubbles. The color bright red on the market, especially in the tourist shop, is marked with "red corundum" and "corundum". The carvings or ornaments of Rubin Stone are actually such synthetic rubies. How to identify true and false rubies The flux method ruby ​​requires a professional to observe its internal characteristics under a high power microscope to be identified. The hydrothermal synthetic ruby ​​synthetic environment mimics the growth environment of natural rubies. The internal features are very similar to natural rubies. It is difficult to distinguish them by general instruments. It is often necessary to use other large instruments such as x-ray instruments. Synthetic gemstones are roughly composed of synthetic rubies, synthetic spinels, synthetic red tourmalines, synthetic red zircons, and cobalt-containing red glass. It is not difficult to identify these seemingly rubies because they are more obvious in various physical properties than real rubies. The difference. Rubies synthesized by different methods have different inclusions, which need to be checked in a professional laboratory or through a magnifying glass. The common feature of synthetic rubies is that the colors are bright and relatively uniform, and it is difficult for the naked eye to find inclusions therein, and the interior is very clean. Most of the natural rubies on the market are more or less known as so-called "cotton mites", that is, a combination of inclusions and internal fissures distributed in a certain direction (controlled by the internal structure of the crystal), sometimes with a filamentous inclusion. For natural rubies that are difficult to find obvious inclusions, long-wave UV lamps (ordinary portable pocket detectors) can be distinguished from synthetic rubies. Natural rubies have strong "dichroism", and rubies emit red and dark red fluorescence under long- and short-wave ultraviolet rays. The so-called dichroism, that is, two shades of red and orange red are seen from different directions. When magnified, the gas-liquid inclusions and solid inclusions in the ruby ​​are rich. The faceted gemstones are visible in the right direction and the facets are ghosted. Even if you only rely on ruby ​​to have "dichroic" means to observe and discriminate, you can immediately exclude a large part of the substitutes and counterfeit goods.
