Ways to Identify the Original Ruby Gemstone

Identifying original ruby gemstones through color and shine.

Ruby is known for its vibrant red color. The color should be intense and evenly distributed, without any noticeable variations or undertones. A genuine ruby typically exhibits a deep red hue. Be cautious of stones that appear too light or have hues of orange or pink, as they may be lower-quality rubies or other gemstones. Examine the gemstone for any visible flaws or inclusions. Natural rubies often have some internal imperfections, such as tiny crystals or rutile needles. However, be wary of rubies that appear flawless or overly perfect, as they may be synthetic or lab-grown.

The refractive index measures how light bends as it passes through a gemstone. Rubies have a relatively high refractive index. A gemologist can use a refractometer to determine the refractive index of a ruby, helping to differentiate it from other gemstones. Rubies are one of the hardest gemstones, scoring 9 on the Mohs scale of mineral hardness. They are second in hardness only to diamonds. Therefore, a genuine ruby should scratch glass and other materials with a lower hardness. Be cautious if a gemstone easily gets scratched or shows signs of wear, as it may not be a genuine ruby.

One of the signs to recognize stone is to pass through rock the rays UV, and a variety of prosthetic these properties are not ruby. In general, all precious stones and jewelry have a similar and counterfeit sample, which is much less expensive than the real sample. How to recognize the main type of counterfeit is one of the most important things that should always be considered when buying jewelry, which in the following section we will discuss three ways to identify it :

  1. Color and shine:
    One way to know the original ruby is a counterfeit of its color. The main type is bright and transparent in the light of lights, and this is a property of ruby, and in counterfeit stones, most of these colors are opaque. If the gemstone is dark red, it may be garnet. Check the solid red color of this gem everywhere, and if you find spots that are scratched and have a different color, it indicates that it is counterfeit.
  2. Compare ruby ​​with a red glass: 
    Precious stones and other types are forged using glass. If the glass and stone were similar, you can see that the stone is fake.
  3. Try to scratch its surface: 
    Gemstones have a high degree of hardness, and as mentioned above, one of the properties of ruby ​​is that only diamond and one other stone can scratch it. Using the same property of ruby, you can largely separate the original type from the counterfeit. Therefore, everybody and object, except for the above, if it can scratch it, it indicates that the stone is counterfeit, and counterfeit stones do not have this property of the original ruby.

Ruby has excellent heat conductivity. Gemologists can use a thermal conductivity meter to measure the gemstone's ability to conduct heat. A high reading indicates that the gemstone is likely a natural ruby. Some rubies exhibit fluorescence under ultraviolet (UV) light. Genuine rubies can display a strong red fluorescence. However, the absence of fluorescence does not necessarily indicate that a ruby is not genuine, as not all rubies fluoresce. Obtaining a certification from a reputable gemological laboratory, such as GIA (Gemological Institute of America), can provide assurance regarding the authenticity and quality of a ruby. A professional gemologist thoroughly examines the gemstone and issues a certificate detailing its characteristics.
