Hardness, defined as resistance to localized plastic deformation caused by indentation or scratching, is a defining characteristic of materials. While diamond is renowned for its exceptional hardness, scoring a 10 on the Mohs hardness scale, it is not impervious to damage. Materials of equal or greater hardness are capable of creating surface imperfections on a diamond. For example, another diamond can create a blemish on a diamond’s surface.
Understanding the factors that can compromise a diamond’s surface integrity is critical for maintaining its value and brilliance. This knowledge informs proper care, storage, and usage, minimizing the risk of accidental damage. Historically, the perception of diamonds as indestructible led to mishandling, resulting in avoidable abrasions. Educating consumers and professionals about the limitations of even the hardest materials is essential for responsible handling.
Therefore, this article will delve into the specific substances and conditions under which a diamond’s surface can be marred. It will also address techniques for preventing damage and methods for assessing and addressing existing imperfections.
1. Diamond (itself)
The paradoxical nature of diamond being both the hardest naturally occurring material and also a potential source of its own scratching requires careful examination. Understanding this dynamic is crucial in the context of preserving diamond surfaces.
-
Diamond Cutting and Polishing
During diamond cutting and polishing, diamond particles are used as the abrasive agent. This process, while necessary for shaping and refining, inherently involves diamond-on-diamond contact at high speeds and pressures. If not meticulously controlled, this interaction can lead to surface imperfections, even as it aims to create brilliance. The microscopic scale of these potential scratches makes detection difficult but highlights the possibility of damage from the same material.
-
Diamond Dust Contamination
Diamond dust, generated from cutting and polishing processes, can become airborne and settle on surfaces, including other diamonds. This contamination introduces microscopic abrasive particles that can cause scratches if the diamond is subsequently rubbed or cleaned improperly. The insidious nature of this fine particulate matter poses a persistent risk, demanding vigilance in handling and storage protocols.
-
Diamond Jewelry Contact
Diamonds mounted in jewelry can scratch each other if they come into direct contact, especially when adjacent stones are set closely together.

Careful jewelry design and wearing habits can mitigate this risk.
-
Industrial Diamond Applications
In industrial applications, diamonds are used for cutting, grinding, and drilling extremely hard materials. While the diamond itself is the cutting agent, the process generates debris that contains diamond particles. These particles, if not properly managed, can contaminate the work environment and pose a risk to other diamond tools or components, leading to self-inflicted damage over time.
Therefore, while diamond’s inherent hardness is unquestionable, the presence of other diamonds, whether as dust, cutting agents, or adjacent stones, constitutes a significant factor when considering “what can scratch a diamond.” This underscores the need for meticulous handling, storage, and cleaning practices to protect these valuable materials.
2. Extreme Pressure
Extreme pressure, even in the absence of abrasive materials, can induce surface damage to diamonds. The diamond’s crystalline structure, while exceptionally strong, possesses inherent cleavage planes, points of weakness along which the material is more susceptible to fracture. Application of sufficient force, particularly along these planes, can initiate cracking or chipping, effectively scratching the diamond’s surface. This is not a traditional scratch in the sense of abrasive removal, but rather a structural compromise manifesting as a visible surface defect. An example is a diamond encountering sudden and intense pressure during setting in jewelry, potentially resulting in a fracture near the setting point.
The importance of understanding pressure-induced damage lies in the practical implications for diamond handling and usage. Jewelers, stone setters, and industrial technicians must be aware of the force limits and potential stress points on a diamond during mounting, cutting, or other processes.

Furthermore, pressure combined with thermal stress can exacerbate the risk, making heat-sensitive procedures particularly hazardous. Advanced techniques, such as finite element analysis, are sometimes employed to model stress distribution within a diamond during various operations, aiding in the prevention of pressure-related damage.
In summary, extreme pressure represents a distinct mechanism by which a diamond’s surface integrity can be compromised. The resulting damage, while not always a conventional scratch, constitutes a visible surface defect caused by structural failure. Understanding the principles of stress distribution and employing careful handling techniques are crucial for minimizing the risk of pressure-induced imperfections, ensuring the longevity and value of the diamond.
3. Abrasive Particles
The presence of abrasive particles represents a significant mechanism through which diamond surfaces can be marred. Unlike purely pressure-related damage, abrasive particles induce scratches through a process of mechanical removal of material. These particles, harder than or of comparable hardness to the diamond itself, act as micro-cutting tools, generating visible or microscopic grooves upon contact and movement across the surface. Common examples of abrasive particles include diamond dust, silicon carbide, aluminum oxide, and certain types of ceramic compounds. The efficacy of these particles in causing scratches depends on their size, shape, hardness, and the force applied during contact. Even seemingly innocuous substances, such as household dust containing minute quantities of harder materials, can contribute to gradual surface degradation over time. The effect is cumulative, with repeated exposure increasing the visibility and severity of the scratches.
Understanding the connection between abrasive particles and diamond surface damage is crucial for implementing effective preventative measures. In jewelry care, regular cleaning with appropriate tools and solutions is essential to remove accumulated abrasive particles. Improper cleaning techniques, such as using rough cloths or abrasive cleansers, can exacerbate the problem.
