Diamonds are often regarded as the ultimate symbol of strength and endurance. Their unmatched hardness has long represented the idea of permanence — a stone that can withstand time itself.
Yet, even with this reputation for resilience, a question occasionally arises among jewelry owners: can a diamond ring become scratched?
The answer is not as straightforward as legend suggests. While diamonds are indeed the hardest of all gemstones, they are not impervious to every form of wear. Understanding how and why this occurs allows you to preserve your diamond’s brilliance for a lifetime.
Understanding What a “Scratch” Really Is
A scratch occurs when the surface of a material is marked or indented by contact with something of equal or greater hardness.
On the Mohs scale of hardness, diamonds rank at the very top — 10 out of 10 — meaning that virtually no other natural material can cut or scratch them.
In practical terms, only another diamond can create a true surface scratch on a diamond.
However, everyday wear introduces other elements that can mimic the appearance of scratches: small abrasions, polish marks, or residue that dulls the surface without physically damaging the gem. Recognizing the difference between these effects is essential to caring for fine jewelry properly.
Can Diamonds Actually Get Scratched?
True scratches on a diamond are exceptionally rare but not impossible. They generally occur under one of the following circumstances:
-
Diamond-to-diamond contact: When two diamonds rub against each other, such as in storage or during wear.
-
Exposure to industrial materials: Certain synthetic compounds and tools can, in theory, mark a diamond’s surface.
-
Accidental abrasion: Repeated contact with other gemstones of high hardness, though less common, may cause micro-abrasions in the polish.
Most instances where clients perceive scratches are instead superficial marks — minor imperfections in the stone’s finish or residue on the surface.
Professional Note: At Little Treasury Jewelers, our experts use high-magnification inspection to distinguish between genuine scratches and polish wear, ensuring appropriate restoration without unnecessary alteration.
Scratches, Chips, and Abrasions — Key Differences
Diamonds may not scratch easily, but they can be susceptible to other forms of surface wear. Understanding the distinction helps identify what kind of care or repair may be needed.
These issues are infrequent with mindful wear but remain possibilities for jewelry that is worn daily.
Why Diamonds Sometimes Appear Scratched
Diamonds may appear scratched even when their structure remains intact. The most common causes include:
-
Residue or film: Lotions, soaps, and natural oils can collect on the surface and dull reflection.
-
Diminished polish: Over years of wear, the diamond’s finely polished surface may develop microscopic lines that scatter light.
-
Metal wear: Prongs or settings in gold or platinum may acquire scratches, creating the illusion that the stone itself is marked.
A professional cleaning or light re-polish can typically restore the diamond’s reflective finish without any invasive work.
What Diamonds Are Truly Vulnerable To
While diamonds resist scratching, they are not immune to fracture or chipping.
-
A sharp blow to an exposed corner — particularly in shapes like marquise, pear, or princess cuts — can cause a small flake to break away.
-
This is due to the diamond’s crystalline structure, which, while hard, has natural planes of cleavage.
Best Practice: Always remove diamond jewelry before engaging in activities that might subject it to sudden impact, and store pieces individually to avoid contact between stones.
Caring for and Protecting Your Diamond Ring
Proper maintenance ensures both longevity and brilliance. These steps will help preserve your diamond’s condition:
-
Clean regularly with mild dish soap, warm water, and a soft brush.
-
Avoid abrasives such as toothpaste, baking soda, or harsh cleaners.
-
Schedule annual inspections with a trusted jeweler to assess settings, prongs, and polish.
-
Store pieces separately, preferably in soft, fabric-lined boxes.
-
Have the metal setting polished periodically to remove fine surface scratches.
Consistent professional care not only maintains the stone’s beauty but also ensures the structural integrity of its setting.
What To Do If You Notice a Mark or Imperfection
If you believe your diamond may be scratched, the next step should always be professional evaluation.
Do not attempt to remove marks at home, as improper cleaning methods can damage the setting or finish.
At Little Treasury Jewelers, our trained specialists carefully examine the piece under magnification to determine whether a true scratch exists. If necessary, we perform precision re-polishing to restore the diamond’s original luster while preserving its carat weight and symmetry.
The Enduring Nature of Diamonds
A diamond’s brilliance is the result of both its natural strength and the craftsmanship behind its cut and polish. Though it can withstand far more than most materials, it benefits from the same respect and attention that all fine jewelry deserves.
At Little Treasury Jewelers, we view diamond care as part of the ownership experience — ensuring that your ring continues to reflect the same clarity, fire, and beauty it held from the very beginning.
