What Are Lab-Grown Diamonds?
Lab-grown diamonds are real diamonds created in highly controlled laboratory environments using advanced technology that replicates the natural diamond-growing process. They possess the same chemical, physical, and optical properties as mined diamonds, making them visually and scientifically identical.
At Bellisa Jewellery, lab-grown diamonds have become one of the fastest-growing choices among couples seeking exceptional quality, ethical sourcing, and greater value without compromising on beauty.

Why Are Lab Diamonds So Popular?
Lab-grown diamonds have transformed the engagement ring industry by offering consumers access to larger, higher-quality diamonds at a more accessible price point.
Many couples choose lab diamonds because they provide:
- Real diamond composition
- Excellent value
- Ethical sourcing
- Larger diamond sizes for the same budget
- IGI certification availability
- Identical appearance to mined diamonds
Our Experience Working With Lab-Grown Diamonds
At Bellisa Jewellery, we have helped thousands of couples across Canada and the United States create custom lab-grown diamond engagement rings.
Over the years, we've seen increasing demand for larger center stones, particularly in oval, elongated cushion, emerald, and radiant cuts. Many clients who initially considered natural diamonds ultimately choose lab-grown diamonds because they can achieve significantly larger carat sizes while maintaining exceptional color and clarity grades.
Among our clients, diamonds between 1.5 and 3 carats remain the most popular range for engagement rings.
Are Lab-Grown Diamonds Real Diamonds?
Yes. Lab-grown diamonds are real diamonds. This is perhaps the most common misconception in the jewellery industry.
Both lab-grown and natural diamonds share:
- Identical chemical composition
- Identical crystal structure
- Identical hardness
- Identical optical properties
Even professional gemologists require specialized testing equipment to determine whether a diamond was created in a laboratory or formed naturally underground.
Lab-Grown Diamond vs Natural Diamond
| Feature | Lab Diamond | Natural Diamond |
|---|---|---|
| Composition | Carbon | Carbon |
| Hardness | 10 | 10 |
| Appearance | Identical | Identical |
| Certification | Available | Available |
| Origin | Laboratory Created | Earth Formed |
| Price | Lower | Higher |
How Durable Are Lab Diamonds?
Lab-grown diamonds rank 10 on the Mohs Hardness Scale, making them the hardest gemstones available.
For comparison:
- Diamond: 10
- Moissanite: 9.25
- Sapphire: 9
- Emerald: 7.5 - 8
This exceptional durability makes lab-grown diamonds ideal for engagement rings intended to be worn daily for a lifetime.
Do Lab Diamonds Pass Diamond Testers?
Yes.
Because lab-grown diamonds are chemically identical to mined diamonds, they pass traditional diamond testers in exactly the same way.
This is one of the key differences between lab-grown diamonds and diamond alternatives such as moissanite or cubic zirconia.

Understanding Lab Diamond Quality: The 4Cs Explained
When selecting a lab-grown diamond, understanding the 4Cs—Cut, Color, Clarity, and Carat Weight—can help you make a more informed decision. These grading factors are used by gemological laboratories such as IGI to evaluate a diamond's quality and value.
Cut
The cut determines how effectively a diamond reflects light. A well-cut diamond will appear brighter, more lively, and more brilliant.
Color
Diamond color is graded from D to Z, with D representing the most colorless diamonds. Most clients choose diamonds within the D–F (Colorless) or G–J (Near Colorless) range.
Clarity
Clarity refers to internal and external characteristics within a diamond. VS1, VS2, and SI1 diamonds often provide an excellent balance between appearance and value.
Carat Weight
Carat measures a diamond's weight, not its visible size. Two diamonds of the same carat weight can appear different depending on their proportions and cut quality.
Our Expert Advice When Choosing a Lab Diamond
At Bellisa Jewellery, we've helped thousands of couples select lab-grown diamonds for their engagement rings. While every client has different priorities, we generally recommend focusing on cut quality first, as it has the greatest impact on a diamond's overall beauty and sparkle.
For most engagement rings, we find that diamonds in the E–F color range and VS1 clarity range offer exceptional value while appearing beautiful to the naked eye.
Rather than maximizing a single characteristic, the best diamond is often one that balances cut, color, clarity, and carat weight according to your personal style and budget.

Are There Any Disadvantages to Lab-Grown Diamonds?
Like any diamond option, lab-grown diamonds may not be the perfect choice for everyone.
Some buyers still prefer the rarity and geological history associated with natural diamonds. Lab-grown diamonds may also have lower resale value compared to certain natural diamonds.
The best choice ultimately depends on your personal priorities and values.

Who Should Choose Lab-Grown Diamonds?
Lab-grown diamonds may be ideal if you:
✓ Want a real diamond
✓ Prefer larger carat sizes
✓ Value ethical sourcing
