Identification of rubies

Color, heat treatment of ruby, fire color, and clarity are all important factors affecting the value of ruby.


  • Color

Europeans call the most brilliant red ruby "Pigeon Blood". Because rubies are too scarce, the mine area will heat the ruby sister rings, which is darker in color and has a purple-blue hue, at around 1000 degrees. The ruby will produce more vivid colors after heated. For the same quality, the carat price of a heated ruby is only a quarter of that of an untreated ruby.


  • Clarity

The clarity requirements for colored gems engraved necklace are less stringent than for diamonds. Because of its own growth characteristics, ruby has many cracks, so its classification of clarity depends on the naked eye. According to the size and location of the internal and external characteristics of the ruby, and the degree of influence of its internal and external characteristics on the overall beauty of the gemstone, the clarity is divided into four levels: extremely pure (C1), pure (C2), relatively pure ( C3), and general (C4).


  • Fire color

Color beauty is determined not only by its color and clarity, but also by fire color. The cut and clarity of the gemstone will affect its color. Therefore, in this grading standard, the area of the crown of the ruby monogrammed necklace is based on the color of the fire. The fire color is divided into four levels: excellent (B1), very good (B2), good (B3), and average (B4).


  • Ruby heat treatment type

Heat treatment is the most common and widely accepted ruby optimization method in the industry. There are very few untreated ruby in the market, and for this reason, the price of it is very high. The standard stipulates that by observing the changes in the ruby's internal inclusions to distinguish whether the gemstone has undergone heat treatment or not. On the premise of determining ruby birthstone necklaces after heat treatment, according to the number of heat treatment residue, the heat treatment of ruby is divided into five categories: Unheated (N), heat treatment without residue (H), heat treatment with little residue (H1), heat treatment middle amount of residue (H2), heat treatment with large amount of residue (H3).

Although cutting is an important indicator for determining the quality of gemstones, the cutting of rubies are not as standard as diamonds, and many factors will affect their cutting during processing.
