As a gemologist with extensive experience in the field of gemstone identification and evaluation, I can provide you with a comprehensive understanding of the topic at hand.
Diamonds are renowned for their exceptional hardness, which is rated as 10 on the Mohs scale, making them the hardest known natural material. This property is one of the key characteristics that distinguishes diamonds from other gemstones.
The idea of scratching a diamond to test its authenticity stems from the fact that diamonds can only be scratched by other diamonds or materials that are harder than them. Historically, the method of scratching a diamond against glass was a common test to determine if the diamond was real. The rationale was simple: if the glass was scratched, the diamond was considered genuine, as it was believed that only a diamond could scratch glass.
However, this method has its limitations and is not entirely reliable. Firstly, not all glass is created equal. Some types of glass, such as tempered or strengthened glass, can be harder and more resistant to scratching than others. In such cases, even a real diamond might not be able to scratch the glass. Conversely, some synthetic materials, like cubic zirconia or synthetic moissanite, are also quite hard and can sometimes scratch glass, leading to false positives in authenticity tests.
Moreover, scratching a diamond against any surface can potentially damage the diamond itself. The facets of a diamond, especially if it is a well-cut gem, are designed to maximize light reflection and brilliance. Any damage to these facets could affect the diamond's appearance and, consequently, its value.
In the modern gemstone industry, there are more sophisticated and accurate methods for determining the authenticity of a diamond. These include:
1. Use of a Diamond Tester: A device that can detect the thermal conductivity of a diamond, which is significantly higher than that of most other materials.
2. Microscopic Examination: A trained gemologist can identify inclusions and other characteristics that are typical of natural diamonds.
3. Spectroscopy: This technique can identify specific light absorption patterns that are unique to diamonds.
4. X-ray Diffraction: It can reveal the crystal structure of the material, which is a definitive way to identify a diamond.
5. Infrared Spectroscopy: This can detect the presence of certain elements or compounds that might indicate a synthetic diamond.
In conclusion, while the scratch test might have been a popular method in the past, it is not a foolproof way to determine if a diamond is real or synthetic. It is always best to rely on professional gemological services and modern testing methods for accurate identification.

In the past, one of the most common techniques to test if a diamond was real or synthetic was to scratch the gem against glass -- if the glass is scraped or scratched, the diamond's real. But this method is not foolproof, as some faux diamonds can also scratch glass.Apr 30, 2013
