The world of diamonds has been transformed. With growing consumer awareness, ethical concerns, and technological advancements, lab-grown diamonds have emerged as a popular alternative to mined diamonds. They offer the same chemical, physical, and optical properties as natural diamonds—without the environmental and ethical concerns associated with traditional diamond mining.
However, despite their growing popularity, many buyers still fall into common pitfalls when purchasing lab-grown diamond rings online. With attractive pricing, polished marketing, and an overwhelming amount of information, how can buyers separate fact from fiction?
Many salespeople will highlight the benefits of lab-grown diamonds but conveniently leave out some key details that could impact your purchase. This guide reveals five crucial truths that online sellers don’t always disclose—helping buyers make informed decisions and avoid costly mistakes.
Truth #1: Lab-Grown Diamonds Are Not Always Perfect
A common misconception is that lab-grown diamonds are flawless because they are created in a controlled environment. While they do tend to have fewer inclusions compared to natural diamonds, they are not inherently perfect.
Why Do Lab-Grown Diamonds Have Inclusions?
Lab-grown diamonds are created using two main methods:
1. HPHT (High-Pressure High-Temperature) – This method mimics the natural diamond formation process but in a lab setting. Some diamonds created this way may contain metallic inclusions from the growth process.
2. CVD (Chemical Vapor Deposition) – This method grows diamonds layer by layer using a gas chamber. CVD diamonds can sometimes show “strain patterns” or small inclusions that affect clarity.
How Clarity Affects a Lab-Grown Diamond’s Beauty
• Higher clarity grades (VS1, VVS1, IF) result in a cleaner look and more brilliance.
• Lower clarity grades (SI1, SI2, I1) may have visible inclusions that affect sparkle.
Why Certification Matters
Not all lab-grown diamonds are graded equally. Some sellers use in-house certification rather than reputable third-party labs, which may overstate the clarity and quality of a diamond. Trusted grading organizations include:
• GIA (Gemological Institute of America)
• NAGL (North American Gemological Laboratory)
DovEggs’ Perspective: Transparency is key. DovEggs ensures that every diamond it sells comes with a certificate from recognized gemological institutions such as NGIC or GEMID. Additionally, we offer the option for further certification through the NAGL agency for those who request it with their purchase of lab-grown diamonds for the dual Certification
Truth #2: Not All “Round” Diamonds Are the Same—Cut is Everything
Many shoppers assume that all round diamonds look the same, but the cut plays a crucial role in determining a diamond’s sparkle. Some sellers may highlight carat weight while downplaying the importance of cut quality.
Modern vs. Vintage Cuts: Which One Is Right for You?
If you’re shopping for a lab-grown diamond ring, it’s essential to understand how different cuts affect a diamond’s look:
-
Round Brilliant Cut (Modern): 58 facets for maximum sparkle – the classic choice for fiery brilliance.
-
Old European Cut (Vintage): Deeper proportions and larger facets for a romantic, "candlelit" glow.
-
Round Rose Cut (Art Deco): A contemporary twist on a historic design, featuring a flat base and domed crown with delicate facet patterns that create soft, ethereal flashes of light.
Each cut has its own character and affects how the diamond interacts with light. For example, a modern round brilliant cut is optimized for maximum sparkle, while an Old Euro cut offers a more vintage glow.
Why Cut Matters Most:
✔ A well-cut diamond appears more luminous, even with lower color/clarity grades.
✔ Unique cuts like our Round Rose Cut offer one-of-a-kind light performance beyond standard rounds.
Pro Tip: When balancing budget, prioritize cut over carat size for the most visual impact!
How to Avoid Cut Quality Mistakes
• Always check the diamond’s cut grade—a well-cut diamond will outshine a poorly cut one, even at the same carat weight.
• Explore distinctive cuts beyond standard rounds, like vintage-inspired and specialty shapes that offer unique light performance.

Truth #3: D Color Isn’t Always the Best Choice
Many buyers believe that D-color (completely colorless) diamonds are always the best choice, but this isn’t necessarily true.
Why G-H Diamonds Can Be a Better Choice
• Warmer tones (G-H color) can enhance the beauty of vintage-inspired cuts, such as Old Mine Cushion and Old Euro Round.
• Colorless diamonds (D-F color) look stunning but may not be worth the premium price if the difference is minimal in real-life viewing.
• The setting affects the color appearance – Diamonds set in yellow or rose gold will naturally appear slightly warmer, making G-H diamonds an excellent choice.
By choosing a slightly lower color grade, buyers can maximize their budget without sacrificing visual appeal.
Truth #4: A Lower Price May Mean Compromises
If a lab-grown diamond ring is significantly cheaper than others of the same specifications, there’s probably a reason. Some common pitfalls include:
1. Poor Cut Quality – A diamond with a lower cut grade may appear dull, even if it has high clarity and color.
2. Non-Reputable Certifications – Some sellers use their own “certifications” that overstate a diamond’s quality.
3. Lower-Quality Metal Settings – A thin metal band or poorly crafted setting can wear down over time.
How to Spot a Good Deal vs. a Red Flag
✔ Compare GIA or NAGL-certified diamonds to those with vague grading reports.
✔ Look at real customer reviews and request actual photos/videos instead of relying on stock images.
✔ Ask about the metal quality—is it solid gold or just gold-plated?
Truth #5: Return Policies and Warranties Matter More Than You Think
Many buyers focus only on the diamond but forget to check the after-sales service. A ring purchase doesn’t end at checkout—what happens if the size is wrong, or if the setting gets damaged?
What to Look for in a Seller’s Policy
• Flexible Return & Exchange Policies – In case the ring doesn’t meet expectations.
• Lifetime Cleaning & Maintenance – Keeps the ring looking pristine over time.
• Resizing & Repair Services – Some sellers charge high fees for resizing, while others offer it as part of their service.
