Diamond is one of the most popular gemstones and is famous for its high value, brilliance and durability. However, there is a common misconception among diamond buyers: whether real diamonds can fog or not. In this blog post, you will learn whether real diamonds can fog and the correct information about it.
What is a Diamond?
First of all, it is important to understand what a diamond is. A diamond is a naturally occurring form of the element carbon in a crystal structure. A diamond is a rare and carefully processed precious stone in nature.
Properties of Diamond
Diamonds have various properties such as hardness, brilliance, and durability. These properties are what distinguish diamonds from other stones. Diamonds have the highest hardness out of 10 on the Mohs hardness scale. This means that diamonds are highly resistant to scratches.
What is Fogging?
The clouding feature of diamonds occurs when water vapor or another substance gets inside the diamond. In this case, the substance inside the diamond creates a cloud inside the diamond, reducing its brilliance.
Real Diamond Fogging
It is very rare for real diamonds to fog. A real diamond has a hard and durable structure and is processed in a way that prevents water or other substances from entering it. Therefore, under normal use, a real diamond is not expected to fog.
Second Hand Diamonds
However, it is important to be careful when purchasing second-hand diamonds. It can be difficult to verify the history and characteristics of second-hand diamonds, especially those without a certificate or assurance document. Therefore, it is important to consult an expert and get detailed information about the condition of the diamond when purchasing a second-hand diamond.
Diamonds are naturally occurring carbon crystals and are rare gemstones. The durability, hardness and brilliance of a diamond are important characteristics that set it apart from other gemstones. Therefore, it is important to understand the common beliefs about real diamonds fogging.
The structure and properties of a diamond reduce the likelihood of clouding. A real diamond may have a flawless crystal structure or may have very small internal flaws (inclusions). However, these internal flaws are not large enough to cause clouding.

However, some exceptional circumstances may cause a diamond to fog. For example, if a diamond is exposed to high temperatures or a strong impact, the molecules inside it may be activated, which may cause fog. However, in daily use or normal jewelry use, a diamond is not expected to encounter such situations.
To summarize, it is rare for real diamonds to fog. Diamonds are naturally hydrophobic and tend to repel water. In addition, the risk of diamond fog can be further reduced with good cutting and processing. However, exceptional circumstances, such as when a diamond is exposed to high temperatures or severe impact, can increase the likelihood of fog.
