The Biggest Myths About Lab Diamonds (And What Buyers in Singapore Should Actually Know)
Lab grown diamonds have moved from niche curiosity to mainstream engagement ring choice in just a few years. Yet despite their growing popularity, misinformation still surrounds them. Buyers often walk into consultations with half-truths: that lab diamonds are fake, that they lose their sparkle, or that they have no resale value.
In reality, most of these claims come from outdated assumptions about the jewellery industry rather than the science behind diamonds themselves. At Diamond Ateliers, our role is not to push one option over another but to help buyers understand how different choices affect beauty, value, and long-term satisfaction.
This guide breaks down the most common myths about lab grown diamonds and explains what actually matters when choosing an engagement ring.
Myth #1: Lab Diamonds Are “Fake Diamonds”
This is the most persistent misconception. Lab grown diamonds are not imitation stones like cubic zirconia or moissanite. They are real diamonds with the same chemical, physical, and optical structure as mined diamonds.
The only difference is their origin. Natural diamonds form deep within the earth over billions of years, while lab diamonds are grown in controlled environments that replicate those natural conditions.
Under a microscope or gemological testing, both are classified as diamonds. The distinction is simply where they came from, not what they are.

Myth #2: Lab Diamonds Don’t Sparkle the Same
Sparkle depends on cut quality, proportions, and light performance — not whether a diamond was mined or grown in a lab.
A poorly cut natural diamond will appear dull. A well-cut lab diamond will look brilliant. The physics of light reflection is identical.
This is why professional jewellers prioritise cut precision above almost every other factor when designing engagement rings.

Myth #3: Lab Diamonds Are Cheap or “Low Quality”
Lower price does not mean lower quality.
Lab grown diamonds are typically more accessible because they bypass the supply constraints of mining. That efficiency allows buyers to allocate budget differently — often choosing larger stones or higher colour and clarity grades.
For many couples in Singapore, this flexibility is the main appeal. Instead of compromising between size and quality, lab diamonds allow both.
You can explore typical engagement ring ranges in our Diamond Ateliers price guide, which explains how budget decisions affect final ring design.
Myth #4: Lab Diamonds Have No Value
Some buyers hear that lab diamonds have “no resale value” and assume they are therefore a bad purchase.
The truth is more nuanced.
Engagement rings — regardless of diamond origin — are rarely purchased as financial investments. Jewellery retail markups, craftsmanship costs, and design factors mean resale values are usually lower than purchase prices for both lab and natural diamonds.
For most couples, the decision is therefore about personal priorities: emotional significance, visual impact, and budget allocation.
In practice, many buyers prefer using their budget toward a ring they truly love rather than preserving theoretical resale value.
Myth #5: Lab Diamonds Are a “Trend” That Will Disappear
Every generation reshapes the engagement ring market.
Platinum replaced yellow gold for a period. Halo settings rose and fell in popularity. Oval diamonds surged in the late 2010s.
Lab diamonds represent a broader structural shift: transparency in pricing and expanded access to high-quality stones.
Today, many modern engagement rings are designed around lab grown diamonds simply because they allow more freedom in the design process.
At Diamond Ateliers, this flexibility often leads to more creative bespoke rings tailored around a couple’s exact vision.
How Lab Diamonds Actually Change the Buying Experience
When buyers understand the facts, the conversation shifts away from myths and toward design.
Instead of debating whether a diamond is “real,” couples start focusing on:
- Stone proportions and brilliance
- Ring architecture and durability
- Finger proportions and stone size balance
- How the ring fits the wearer’s lifestyle
This is where bespoke design becomes valuable.
At Diamond Ateliers, each ring begins with consultation, 3D design development, and refinement before the final piece is produced. This approach allows couples to explore different diamond sizes, settings, and proportions before committing.

What Buyers in Singapore Should Focus on Instead
If you’re choosing between lab and natural diamonds, the most important question is not which one is “better.”
The real question is: which option aligns best with your priorities?
Some buyers value geological rarity. Others prioritise size, brilliance, or design flexibility within a specific budget.
Both choices can produce extraordinary engagement rings when the design and stone selection are done thoughtfully.
Understanding the myths simply removes the noise from that decision.
Final Thoughts
Lab diamonds are not fake, they do not sparkle less, and they are not simply a passing trend. They are one of several legitimate ways to create a meaningful engagement ring.
The key is making the decision with accurate information rather than industry myths.
