When shopping for a diamond, durability is often one of the biggest concerns. Many buyers wonder: do lab diamonds scratch? The short answer is yes, but only under specific conditions. Lab grown diamonds are among the hardest materials on Earth, making them highly resistant to scratches during everyday wear. However, like all diamonds, they are not completely scratch-proof.
Understanding how lab diamonds respond to scratches can help you make a more informed buying decision and choose a stone that will maintain its beauty for decades.

Understanding Diamond Hardness
To understand whether lab diamonds scratch, it helps to know how diamond hardness works.
Diamonds rank 10 on the Mohs Hardness Scale, which measures a material's resistance to scratching. This makes diamonds harder than all other gemstones, including:
- Sapphire
- Ruby
- Emerald
- Topaz
- Moissanite
Because lab grown diamonds have the same crystal structure as natural diamonds, they share the exact same hardness rating.
Whether a diamond forms naturally underground over billions of years or is created in a laboratory, its hardness remains identical.

Do Lab Diamonds Scratch Easily?
No, lab diamonds do not scratch easily.
In fact, they are extremely resistant to scratches compared to nearly every other gemstone used in jewelry.
Daily activities such as:
- Typing
- Cooking
- Driving
- Exercising
- Washing hands
typically will not scratch a lab diamond.
The diamond's surface is strong enough to withstand regular wear without losing its polish or brilliance.
For most owners, a lab diamond engagement ring or piece of jewelry can maintain its appearance for decades with proper care.

Can Lab Diamonds Be Scratched at All?
Yes, lab diamonds can be scratched under certain circumstances.
A common misconception is that diamonds are indestructible. While diamonds are exceptionally hard, they can still be scratched by another diamond.
Since diamonds are the hardest naturally occurring material, only another diamond can reliably scratch a diamond's surface.
For example:
- Two loose diamonds rubbing together during storage
- Diamond jewelry pieces touching each other
- Diamond cutting and polishing processes
can create scratches or surface abrasions.
This is why jewelers store loose lab diamonds separately and use protective packaging during transportation.
Scratch Resistance vs Toughness
Many buyers confuse hardness with toughness.
These are two different properties.
Hardness
Hardness refers to resistance against scratching.
Lab diamonds score 10 on the Mohs scale, making them highly scratch resistant.
Toughness
Toughness refers to resistance against chipping, cracking, or breaking.
Although diamonds are extremely hard, they can chip if struck at certain angles with enough force.
For example:
- Dropping a ring onto a hard surface
- Hitting a diamond against metal equipment
- Impact from sports activities
may cause damage to the diamond or its setting.
Fortunately, such incidents are relatively uncommon during normal wear.

Do Lab Diamonds Get Scratched More Than Natural Diamonds?
No.
One of the biggest myths surrounding lab grown diamonds is that they are softer or less durable than natural diamonds.
This is incorrect.
Lab diamonds and natural diamonds are:
- Made of pure carbon
- Have identical crystal structures
- Share the same physical properties
- Have the same hardness rating
As a result, neither type scratches more easily than the other.
When comparing durability, there is effectively no difference between a certified lab diamond and a natural diamond.

What Can Damage a Lab Diamond?
Although scratching is unlikely, several factors can potentially damage a lab diamond.
Hard Impacts
Strong impacts may chip a diamond, especially around pointed areas such as:
- Princess cuts
- Pear shapes
- Marquise cuts
- Heart shapes
Protective settings can reduce this risk.
Poor Storage
Storing multiple diamonds together can cause them to rub against each other.
Because diamonds can scratch other diamonds, separate storage is recommended.
Worn Jewelry Settings
Sometimes the stone remains undamaged while the setting loosens.
Regular inspections help ensure your diamond stays secure.

How to Prevent Scratches on Lab Diamonds
Proper care helps preserve the appearance of your diamond for years.
Store Jewelry Separately
Keep diamond jewelry in individual pouches or compartments.
This prevents diamonds from coming into contact with one another.
Remove Jewelry During High-Impact Activities
Consider removing rings when:
- Weightlifting
- Heavy construction work
- Gardening
- Contact sports
This reduces the risk of chips or damage.
Clean Your Diamond Regularly
Dirt and oils can make a diamond appear less brilliant.
A simple cleaning routine with warm water, mild soap, and a soft brush can help maintain maximum sparkle.
Schedule Professional Inspections
A jeweler can inspect the setting and identify any issues before they become serious problems.

Do Scratches Affect Sparkle?
Minor surface abrasions can affect how light travels through a diamond.
However, because lab diamonds rarely develop scratches during normal use, most owners never notice a reduction in brilliance.
In cases where a diamond develops surface wear after many years, professional polishing can often restore its original appearance.
The vast majority of lab diamond owners enjoy long-term sparkle without any noticeable scratching.
Are Lab Diamonds Durable Enough for Everyday Wear?
Absolutely.
Lab grown diamonds are one of the best choices for daily jewelry because they combine exceptional beauty with outstanding durability.
They are particularly popular for:
- Engagement rings
- Wedding bands
- Earrings
- Pendants
- Tennis bracelets
Because of their hardness and resistance to scratching, they can withstand everyday use far better than most alternative gemstones.
For buyers seeking long-term value and durability, lab diamonds are among the strongest options available.

What Should You Look for When Buying a Lab Diamond?
While durability is rarely a concern, there are other important factors to compare when shopping for lab diamonds.
Choose Certified Diamonds
Always look for certification from respected grading laboratories.
Certification confirms the diamond's quality and characteristics.
Compare the Four Cs
Evaluate:
- Cut
- Color
- Clarity
- Carat weight
A well-cut diamond often appears more brilliant than a larger stone with inferior proportions.
Compare Multiple Options
Before making a purchase, compare several stones to find the best balance between quality and price.
Browsing different loose lab diamonds can help you identify stronger value opportunities and better specifications within your budget.
Focus on Cut Quality
Among all diamond characteristics, cut quality has the greatest influence on sparkle and visual performance.
Prioritizing cut often delivers the best overall appearance.

Lab Diamonds vs Other Gemstones for Scratch Resistance
Here's how lab diamonds compare to popular gemstones:
| Gemstone | Mohs Hardness |
|---|---|
| Diamond (Lab or Natural) | 10 |
| Moissanite | 9.25 |
| Sapphire | 9 |
| Ruby | 9 |
| Topaz | 8 |
| Emerald | 7.5 to 8 |
This comparison highlights why diamonds remain the preferred choice for engagement rings and everyday jewelry.
Their superior hardness helps them resist wear better than nearly any alternative gemstone.
Final Thoughts
So, do lab diamonds scratch? While lab diamonds can technically be scratched by another diamond, they are extraordinarily resistant to scratches during normal wear. Their hardness is identical to natural diamonds, making them one of the most durable gemstone choices available.
For most buyers, scratching should not be a concern. Instead, focus on comparing certified lab grown diamonds based on cut, color, clarity, and value. With proper care and storage, a lab diamond can maintain its beauty, brilliance, and durability for generations.
