In the jewelry market, diamonds have become the dream of many people because of their unique luster, rarity and eternal value. However, the market is flooded with all kinds of diamonds, from truly pure and flawless natural diamonds to a variety of synthetic and artificial diamonds, as well as some counterfeits that appear to resemble the real thing.

• Understanding the basic properties of diamonds is the basis for identifying the real ones. Real diamonds have the following characteristics:
• Hardness: Diamond is the hardest substance in nature, with a Mohs hardness of 10.
• Optical properties: Diamonds have a high refractive index and dispersion, which makes them present a unique flicker effect when exposed to light.      

• Density: The density of diamonds is about 3.52 grams/cubic centimeter, which is higher than many common materials.
• Chemical composition: Diamond is composed of pure carbon, carbon is formed under high pressure and high temperature environment.

• Scratch test: Real diamonds can not be scratched by ordinary glass or quartz, you can use this method to make a preliminary judgment.

• Specific gravity test: Put the diamond in the water, the real diamond will float a little, because its density is slightly higher than water (but be careful to avoid damaging the jewelry).
• UV reaction: Under strong ultraviolet light, real diamonds will emit blue-white fluorescence, while most counterfeit products will not have this reaction.

• Real diamonds show a high degree of resistance to sulfuric acid, hardly reacting or producing only slight surface changes. This is because diamonds are mainly made of carbon, which does not react with sulfuric acid. In contrast, most synthetic diamonds, some glass or plastic imitations, will react with sulfuric acid because they contain different chemical components, such as silicon, aluminum, lead, etc.
• Diamond is an extremely hard mineral with good thermal stability. Therefore, when the diamond is heated to very high temperatures, it should be able to withstand long periods of heating without melting or decomposition. In contrast, most non-natural diamonds, including certain man-made stones (such as silicon carbide or certain glass products), may melt or decompose when heated, releasing gases or creating other visible changes.

Professional Testing & Professional Diamond Appraisal

• Laser drilling test: Some high-tech means can use lasers to form specific marks inside the diamond as the basis for authenticity identification.
• Magnifying glass inspection: Real diamonds often have "inclusions," natural features such as cracks, spots or bubbles inside, while counterfeits may not have these details.
• Professional appraisal: Finally, the most reliable method is to send to a professional jewelry appraisal institution for detailed testing. These institutions have advanced equipment and technology to accurately identify the authenticity of diamonds.

Identifying the authenticity of a diamond is a complex process that involves multiple aspects of knowledge and skill. For non-professionals, understanding basic identification methods is necessary, but seeking professional identification is still the safest option when buying expensive diamonds. Hopefully, this guide will help you make informed decisions about future purchases.
