First of all, we should recognize the blood relationship of ruby. Ruby is a kind of corundum. Even if some rubies such as tourmaline (tourmaline) are close in color, they are not ruby. Natural rubies are rare and precious, but it is not too difficult to make them, so industrial rubies are all man-made. Trace chromium makes it red. The higher the chromium content, the redder it is. The reddest one is commonly known as "pigeon blood red". Ruby has a beautiful color. Under the light source, it can reflect beautiful and moving six starlight, commonly known as six lines. This is due to the special crystal structure of ruby, which is its unique optical phenomenon. Ruby has transparent, semi transparent and opaque shapes, and the colors are water red, pink, pigeon blood red, rose red and other colors. Because large gemstones are very rare, the rubies with large grains usually seen are fake. There are two cases of fake rubies: the first is to pass off low-grade rubies with red color as rubies, and all fake rubies have no unique color shape and light property of rubies. The second is synthetic ruby. Artificial rubies are very similar to natural rubies in terms of specific gravity, hardness, color, etc. It can be judged intuitively that the synthetic ruby is homogeneous in texture, free from natural impurities, uniform and regular in color, often with large particles and a lack of natural feeling.

In addition, what are the standards for collecting rubies? This standard is similar to the general standard for gem evaluation. The main standards are: color, impurities, carat and cutting. In color, it is better to be VIVID RED or RED; Naturally, the less impurities, the better. It is better when it is invisible to the naked eye; Carat number means that the weight of a gem must be at least 1 carat before it is worth collecting; In terms of cutting, there should be at least 40% of fire lights. In addition, the origin of ruby is also very important, and an authoritative identification certificate is also required.

Generally speaking, "pigeon blood" is used to describe the rich and bright color of ruby, just like pigeon blood, which is generally recognized as the most beautiful color of ruby. Because rubies usually have dichroism, rubies generally appear purple gules Or pink, it is not easy to achieve pigeon blood red. At present, only rubies produced in Myanmar have pigeon blood level, which is rare and precious, and the output is extremely low. At present, the color level of ruby with the best color in the world is called VIVID RED. If it is indicated by PIGEON BLOOD, the value of ruby will be counted in cities.

In fact, most rubies on the market are heat treated, and the industry also accepts ruby heat treatment. If the consumer is "no burning control", and wants to pursue ruby without heat treatment, but also has high color quality, it must pay more. Generally speaking, the value of ruby after heat treatment will not drop, but the ruby without heat treatment and excellent quality is naturally more valuable.
