You've probably heard conflicting stories about lab grown diamonds, and now you're not sure what to believe. Some people say they're fake, others claim they lose value instantly, and a few insist they look different from natural diamonds. As a professional jeweller, I hear these concerns daily from buyers just like you. This article will clear up the most common myths so you can make your purchase decision based on facts, not fear or misinformation.

Myth 1: Lab Grown Diamonds Are Not Real Diamonds

This is the biggest myth I encounter, and it stops many buyers from even considering lab grown diamonds. Let me be clear: lab grown diamonds are chemically, physically, and optically identical to natural diamonds. They have the same carbon crystal structure, the same hardness (10 on the Mohs scale), and the same brilliance. The only difference is their origin story. One forms in the earth over millions of years, the other forms in a controlled laboratory environment over weeks.

Both are certified by the same gemological institutes using identical grading standards. A GIA or IGI certificate for a lab grown diamond uses the same cut, color, clarity, and carat criteria as for natural stones. When you look at them side by side, even experienced jewellers cannot tell them apart without specialized equipment. If you're worried about authenticity, remember that lab grown diamonds pass every test that defines what makes a diamond real. The choice between lab grown and natural is about preference and values, not about one being real and the other being fake.

Myth 2: Lab Grown Diamonds Look Fake or Different

Many buyers ask me if lab grown diamonds have a different sparkle or color. The answer is no. Lab grown diamonds display the same fire, brilliance, and scintillation as natural diamonds because they are made of the exact same material. The quality of appearance depends entirely on the cut grade, not the origin. A well-cut lab grown diamond will outshine a poorly cut natural diamond every time.

Some confusion comes from mixing up lab grown diamonds with diamond simulants like cubic zirconia or moissanite. These are different materials entirely and do look different under scrutiny. Lab grown diamonds, however, are pure carbon arranged in a diamond crystal structure. They reflect light the same way, disperse colors identically, and feel the same weight in your hand. If someone tells you they can spot a lab grown diamond just by looking, they're either guessing or confusing terms. Trust the certification and the cut quality, and your diamond will look exactly how you want it to, regardless of where it was grown.

Myth 3: Lab Grown Diamonds Have No Resale Value

This concern comes up often, especially for engagement rings. The truth is more balanced than the myth suggests. All diamonds, whether natural or lab grown, depreciate when you leave the store. Jewelry is not typically a strong financial investment unless you're buying rare, high-grade natural stones at auction level. For most buyers, a diamond's value is personal and symbolic, not financial.

Lab grown diamonds do have lower resale values compared to natural diamonds right now, mostly because the market is still developing and supply is increasing. However, natural diamonds also rarely resell for what you paid unless they are exceptionally rare. What you should focus on is the value you get at purchase. Lab grown diamonds cost 60 to 80% less than comparable natural diamonds, which means you can buy a larger or higher quality stone for the same budget. If you plan to wear and enjoy your jewelry rather than sell it later, lab grown diamonds offer outstanding value. Think about what matters more: slightly better resale potential, or getting the exact diamond you want today within your budget.

Myth 4: Lab Grown Diamonds Are Low Quality or Flawed

Some people assume that because lab grown diamonds are made quickly, they must be lower quality. This is not accurate. Lab grown diamonds are available in the full range of clarity and color grades, just like natural diamonds. You can find flawless lab grown diamonds, and you can also find included ones. The growth process does not automatically determine quality.

As Ashish Sukhadiya, master jeweller at Gemone Diamonds, says: "The controlled environment of lab growth actually allows us to produce diamonds with fewer inclusions and better color consistency than many natural stones, because we can monitor temperature and pressure precisely throughout the process." This means you often get cleaner stones at better prices. The key is to check the grading report. Look for clarity grades of VS2 or higher and color grades in the near-colorless range (G-H) or better if you want excellent visual quality. The lab origin does not limit quality. Your budget and preferences do. Choose based on the certified grade, not assumptions about the source.

How Much Should You Expect to Pay for Lab Grown Diamonds

One of the most common questions I hear is about pricing confusion. Buyers see lab grown diamonds advertised at dramatically lower prices and wonder if something is wrong. Nothing is wrong. Lab grown diamonds simply cost less to produce, and that savings passes to you. A one-carat round brilliant lab grown diamond with excellent cut, G color, and VS2 clarity typically costs between $800 and $1,500. The same specs in a natural diamond would run $4,000 to $6,000 or more.

Several factors affect the price. Cut quality has the biggest impact on both cost and beauty. An excellent cut will cost more but look far better than a good or fair cut. Clarity and color also matter, but you can often go slightly lower on these grades without visible difference. Carat weight increases price exponentially, so a two-carat stone costs more than double a one-carat. Certification from GIA or IGI adds to the price but gives you confidence in what you're buying. At Gemone Diamonds, we help buyers balance these factors to get the best stone within their budget. If you have $2,000, you can get a stunning 1.5-carat lab grown diamond. If you have $5,000, you can go larger or choose a fancy shape with top grades. Decide what matters most to you, then work with a jeweller who will show you certified options in your range.

Myth 5: Lab Grown Diamonds Are Bad for the Environment

This myth circulates widely, often pushed by natural diamond marketing. The reality is more complex. Lab grown diamonds do require energy to produce, and if that energy comes from fossil fuels, there is an environmental cost. However, many lab grown diamond producers now use renewable energy sources, which dramatically reduces their carbon footprint. Natural diamond mining, on the other hand, involves land disruption, habitat loss, water use, and significant energy for extraction and transport.

No product is perfectly green, but lab grown diamonds generally have a smaller environmental impact when produced responsibly. If this matters to you, ask your jeweller about the source and production methods. Some companies provide transparency reports showing their energy sources and sustainability practices. What you should avoid is assuming one option is automatically better without checking the facts. Both lab grown and natural diamonds can be produced with care or with harm. Make your choice based on verified information, not sweeping claims. If you value sustainability, look for certified responsible sources in either category.

Myth 6: Lab Grown Diamonds Will Lose All Value Soon

This myth suggests that because lab grown diamonds are becoming easier to produce, prices will crash and your purchase will become worthless. While it's true that lab grown diamond prices have decreased over the past few years due to improved production and competition, this does not mean your diamond loses all value. Prices have started to stabilize as the market matures. More importantly, the value of your jewelry is tied to what it means to you and how you use it, not just resale potential.

Consider this: when you buy any piece of fine jewelry, you pay for the design, the craftsmanship, the setting, and the gemstone. Even if the diamond component decreases slightly in market price, the complete piece retains sentimental and functional value. Many buyers choose lab grown diamonds specifically because they care more about getting a beautiful stone now than about future resale. If your goal is to wear and enjoy your ring for decades, price fluctuations in the secondary market won't affect your daily experience. Focus on buying a quality piece you love, and the long-term value will take care of itself through the joy and meaning it brings.

Myth 7: Jewellers Won't Work With Lab Grown Diamonds

Some buyers worry that if they choose a lab grown diamond, they'll have trouble finding a jeweller to set it, resize it, or repair it later. This is outdated information. The jewelry industry has widely accepted lab grown diamonds, and most professional jewellers now work with them regularly. There is no difference in how you set, clean, or repair a lab grown diamond compared to a natural one because they are the same material.

Any jeweller who works with natural diamonds can work with lab grown diamonds using the exact same tools and techniques. If you encounter resistance, it's usually about personal preference or business model, not technical capability. Many jewellers, including independent designers and larger retailers, now offer lab grown options because customers ask for them. When you bring your ring in for cleaning, resizing, or stone tightening, the jeweller treats it exactly the same. Your maintenance routine, insurance, and care instructions are identical. Don't let this myth hold you back from choosing the stone you want. The industry has moved forward, and services are fully available.

Buying Tips for Lab Grown Diamonds:

• Always buy certified stones from GIA, IGI, or another reputable lab so you know exactly what you're getting
• Prioritize cut quality over carat size because a well-cut smaller diamond looks better than a poorly cut larger one
• Ask about the return policy and warranty before purchasing, especially when buying online
• Compare prices from multiple sellers, but make sure you're comparing identical grades and certifications
• Choose a setting that protects the stone and suits your daily lifestyle, not just current trends
• Work with a jeweller who answers your questions clearly and does not pressure you toward one option

Pros and Cons Based on Real Buyer Situations:

Pros:

• You get significantly more size or quality for the same budget, which matters if you have a specific look in mind
• Ethical sourcing is clearer because the supply chain is shorter and more traceable
• Identical beauty and durability to natural diamonds, so daily wear and enjoyment are the same
• Increasingly available in all shapes, sizes, and quality grades, giving you full choice

Cons:

• Lower resale value if you plan to sell or trade the stone later, though this applies to most jewelry purchases
• Some traditional buyers or family members may not understand or accept lab grown diamonds due to older beliefs
• Market prices may continue to adjust as production scales, though this affects future purchases more than your current one

Conclusion:

Lab grown diamonds are real, beautiful, and valuable for the right buyer. The myths you've heard often come from outdated information or misunderstanding. Now that you know the facts, you can decide based on what actually matters: your budget, your values, and the look you want. Whether you choose lab grown diamonds or natural stones, the most important thing is buying certified quality from a jeweller you trust.
