How to determine the authenticity of rubies

  I. Appearance

  we can take a preliminary look at the authenticity of rubies by looking at their appearance:

    1. Bright and even color: a real ruby is bright and even in color. If the color is uneven or slightly grayish-black, it is likely to be a synthetic ruby.

    2. A ruby with a unique flame effect: if you cover the light source with your hand and let the light through the stone illuminate white paper, a genuine ruby will have a unique flame effect, appearing as a single beam of light. If there are "silver bands" or "sweet peas", the ruby may be a glued ruby.

    3. Radiation spots: rubies also have natural radiation spots, which do not affect the quality of the ruby. However, a common feature of synthetic rubies is that they have too many radiation spots, even in an orderly fashion, making them look unusually delicate.

  II. Test tools

  It is also a very practical method to test the authenticity of rubies through testing tools, which are currently available in the market

    1. Blue light pen: rubies will show different feedback under different light wavelengths, real rubies do not reflect light under blue light.

    2. Thermal conductivity meter: rubies usually do not conduct electricity, the temperature does not easily rise after heating, only artificially produced synthetic rubies conduct electricity.

    3. UV light: real rubies emit an attractive red fluorescence, while synthetic rubies emit a blue fluorescence.

  IV. Professional identification

  If the above methods are difficult to determine the authenticity of rubies, it is best to seek professional help. There are many well-known jewelry appraisal organizations in the market, and there are also some certification organizations that provide gemstone certificates and proofs. It is best to choose a qualified and reputable formal institution for testing.

  However, it should be noted that no identification is a 100% guarantee, so before buying rubies, you also need to know the credibility and qualifications of the supplier, and you need to follow the rules of the market to buy gems and not blindly believe in low prices.

  In conclusion, rubies as a precious stone are expensive, so you must be especially careful when buying them, starting with the appearance, then testing them with tools and finally seeking professional help to better determine their authenticity and avoid being cheated.
